Entry point for all storage engine operations (open, close, read, write, DDL). Implements row-at-a-time interface for MariaDB, translating to DuckDB batch operations. + +- **`DuckdbManager`** (`duckdb_manager.cc/h`) — Singleton owning the `duckdb::DuckDB` instance. Created once at plugin init, creates connections for each thread. Database file stored as `duckdb.db` in MariaDB data directory. + +- **`DuckdbThdContext`** (`duckdb_context.cc/h`) — Per-thread context holding a `duckdb::Connection`, transaction state, and appenders. Attached to MariaDB's THD. Manages BEGIN/COMMIT/ROLLBACK lifecycle and session variable propagation (timezone, optimizer flags, collation). + +- **DDL/DML Convertors** (`ddl_convertor.cc/h`, `dml_convertor.cc/h`) — Translate MariaDB SQL structures (TABLE, Field, Alter_info) into DuckDB-compatible SQL strings. Handle identifier quoting differences (MariaDB backticks → DuckDB double quotes) and type mapping. + +- **`DeltaAppender`** (`delta_appender.cc/h`) — Batched write path. Accumulates INSERT/UPDATE/DELETE rows using DuckDB's Appender API into a temporary buffer table, then flushes as a single DuckDB DML statement at commit time. `DeltaAppenders` manages per-table appender instances. + +- **Select handler / Query pushdown** (`ha_duckdb_pushdown.cc/h`) — Implements MariaDB's `select_handler` interface to push entire SELECT queries down to DuckDB. Registered via `hton->create_select` and `hton->create_unit`. Supports pure-DuckDB queries and cross-engine joins. + +- **Cross-engine scan** (`cross_engine_scan.cc/h`) — Enables DuckDB to read from non-DuckDB tables (e.g. InnoDB) during cross-engine joins. Registers a `_mdb_scan` table function and a replacement scan callback in DuckDB. Uses a thread-local registry of external tables. + +- **Type mapping** (`duckdb_types.cc/h`) — Converts between MariaDB field types and DuckDB types. `store_duckdb_field_in_mysql_format()` reads DuckDB values back into MariaDB row format. + +### SQL generation conventions + +All generated SQL must use **double quotes** for identifiers (DuckDB follows SQL standard), not backticks. The `SELECT_LEX::print()` output from MariaDB uses backticks and must be post-processed. See `docs/mariadb-duckdb-incompatibilities.md` for known function name rewrites and type mapping issues. + +### DuckDB source and patches + +DuckDB source is at `third_parties/duckdb/` (git submodule). No patches are applied — all compatibility is handled at runtime via `duckdb_mysql_compat.cc`. The build produces a static library; `_GLIBCXX_DEBUG` is explicitly undefined in CMakeLists.txt to avoid ABI mismatch with MariaDB's debug build. + +### Configuration + +`duckdb.cnf` — MariaDB config snippet that loads `ha_duckdb.so`.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1335 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License.

Queries are translated and executed by the DuckDB engine. InnoDB and DuckDB tables coexist in the same database. + +## Building + +The engine is built as part of the MariaDB server tree. It lives under `storage/duckdb/` and uses `ExternalProject_Add` to build DuckDB v1.5.2 from source. + +Until the patch is accepted into MariaDB upstream, clone one of the prepared branches from the server fork and then clone the plugin: + +```bash +# Pick the branch matching your target MariaDB version +git clone -b bb-11.4-duckdb https://github.com/drrtuy/mdb-server.git mariadb-server +# or: -b 11.8-duckdb +# or: -b 12.3-duckdb +cd mariadb-server + +# Clone the DuckDB engine plugin +git clone --recurse-submodules https://github.com/MariaDB/duckdb-engine storage/duckdb/duckdb + +# Install build dependencies (requires root) +./storage/duckdb/duckdb/build.sh -D + +# Build and install +./storage/duckdb/duckdb/build.sh +``` + +### Build packages + +**RPM** (Rocky/Fedora/Amazon Linux): + +```bash +./storage/duckdb/duckdb/build.sh -p +``` + +**DEB** (Debian/Ubuntu): + +```bash +./storage/duckdb/duckdb/build.sh -p +``` + +## Cross-Engine Queries + +The engine supports cross-engine joins — a single `SELECT` can combine DuckDB tables with tables from other engines (e.g. InnoDB). When the query planner detects a mix of engines, the `select_handler` does the following: + +1. Opens the non-DuckDB tables via MariaDB's handler API and registers them in a thread-local table registry. +2. Derives a per-table predicate from the query's `WHERE` (via `make_cond_for_table`) and registers it alongside each external table. +3. Pushes the **entire query** — including all `WHERE`, `JOIN`, `GROUP BY`, and `ORDER BY` clauses — down to DuckDB as a single SQL statement. +4. DuckDB's replacement scan callback transparently redirects references to non-DuckDB tables to the `_mdb_scan` table function. + +The `_mdb_scan` table function does **not** loop over the handler directly. On its first call it lazily spawns a **cooperative fiber** (stack-switching runtime borrowed from `libmariadb`) running on a dedicated background `THD`. Inside the fiber it builds a synthetic, projection- and predicate-pushed +`SELECT FROM . [WHERE ]` +and executes it through the **full MariaDB pipeline** (`lex_start` → `parse_sql` → `mysql_execute_command`). A custom `select_result_interceptor` (`select_to_duckdb`) converts each result row's `Item`s into a DuckDB `DataChunk`; when a chunk fills (`STANDARD_VECTOR_SIZE`) the fiber **yields** back to DuckDB, which consumes the chunk and resumes the fiber for the next batch. + +Because the external scan runs through `mysql_execute_command`, it uses the **MariaDB optimizer and all available access paths** (index range/ref access, etc.), and the pushed `WHERE` predicate is evaluated by MariaDB *before* rows reach DuckDB. On the DuckDB side, the full query text lets DuckDB's optimizer reorder joins, build hash tables, and run all aggregation/sorting over the streamed rows. A direct `ha_rnd_next` loop is retained only as a fallback when no fiber is used. + +This means queries like the following just work: + +```sql +SELECT d.id, d.amount, i.name + FROM analytics.orders d -- ENGINE=DuckDB + JOIN inventory.products i -- ENGINE=InnoDB + ON d.product_id = i.id + WHERE d.amount > 1000; +``` + +DuckDB handles the join, aggregation, and sorting; InnoDB rows are produced on demand by a fiber-driven MariaDB query. No data copying or ETL is required. + +## Current Limitations + +- **DECIMAL precision > 38** — DuckDB supports up to 38 digits; wider MariaDB DECIMALs will fail on DDL conversion. +- **Some MariaDB functions are yet not pushdown-compatible** — `GROUP_CONCAT()`, `DATE_FORMAT()`, `JSON_CONTAINS()`, `FOUND_ROWS()`, `LAST_INSERT_ID()`, and a few others have no DuckDB equivalent or differ in syntax. Such queries fall back to MariaDB execution. +- **Strict GROUP BY** — DuckDB rejects `SELECT` columns not in `GROUP BY` and not aggregated, even when MariaDB's `sql_mode` allows it. +- **XA transactions** — `XA PREPARE` is not supported by the engine. +- **Collations** — MariaDB UCA-based collation rules are approximated via DuckDB's built-in `NOCASE`/`NOACCENT` collations for UTF-8 charsets; non-UTF8 charsets fall back to binary comparison. See [`docs/collation-mapping.md`](docs/collation-mapping.md) for the full mapping and known gaps. +- **Cross-engine scan is yet single-threaded** — each external (non-DuckDB) table is produced by a single fiber-driven MariaDB query (`_mdb_scan` reports `MaxThreads() == 1`); only the DuckDB side of the query is parallelized. +- **ALTER COLUMN DROP DEFAULT** — not propagated to DuckDB catalog. +- **Timezone propagation** — `TIMESTAMP` columns are stored as `TIMESTAMPTZ`; timezone must be set consistently between MariaDB and DuckDB contexts to avoid shifts. + +See [`docs/mariadb-duckdb-incompatibilities.md`](docs/mariadb-duckdb-incompatibilities.md) for a detailed compatibility matrix. + +## License + +This project is licensed under the GNU General Public License v2.

AliSQL is a MySQL branch developed at Alibaba Group and extensively used in their production infrastructure. The December 2025 open-source release of AliSQL 8.0 included integration of DuckDB as a native storage engine, providing a valuable reference implementation and validating the viability of embedding DuckDB inside a MySQL-compatible server. The DuckDB Engine for MariaDB draws heavily on this experience. + +**The DuckDB Project** — None of this would be possible without the remarkable work of the [DuckDB team](https://github.com/duckdb/duckdb). DuckDB has grown from an academic research project into one of the most impressive analytical engines available today — fast, embeddable, dependency-free, and released under the permissive MIT License. Its clean C++ codebase and well-defined embedding API are what make integrations like this one feasible. diff --git a/storage/duckdb/build.sh b/storage/duckdb/build.sh new file mode 100755 index 0000000000000..c6e4f08e2d00a --- /dev/null +++ b/storage/duckdb/build.sh @@ -0,0 +1,391 @@ +#!/bin/bash + +set -e +set -o pipefail + +SCRIPT_LOCATION=$(dirname "$0") +source "$SCRIPT_LOCATION/utils.sh" +MDB_SOURCE_PATH=$(realpath "$SCRIPT_LOCATION"/../../../) +DUCKDB_SOURCE_PATH=$(realpath "$SCRIPT_LOCATION") +BUILD_PATH=$(realpath "$MDB_SOURCE_PATH"/../DuckdbBuildOf_$(basename "$MDB_SOURCE_PATH")) +CPUS=$(getconf _NPROCESSORS_ONLN) +BUILD_TYPE_OPTIONS=("Debug" "RelWithDebInfo") +BUILD_TYPE="${BUILD_TYPE:-}" +DISTRO_OPTIONS=("ubuntu:22.04" "ubuntu:24.04" "debian:12" "rockylinux:8" "rockylinux:9") +DEFAULT_MDB_DATADIR="/var/lib/mysql" +USER="mysql" +GROUP="mysql" +INSTALL_PREFIX="/usr/" +GCC_VERSION="12" + +usage() { + echo "Usage: $0 [options]" + echo " -t Build type: ${BUILD_TYPE_OPTIONS[*]} (interactive if omitted)" + echo " -d Distro: ${DISTRO_OPTIONS[*]} (auto-detected if omitted)" + echo " -j Number of parallel jobs (default: $CPUS)" + echo " -c CI mode: only build, skip install" + echo " -p Build packages (DEB or RPM)" + echo " -S Start MariaDB after build" + echo " -n No clean: keep existing data files" + echo " -D Install build prerequisites (requires root/sudo)" + echo " -u Build unit tests" + echo " -R Use gcc-toolset-\${GCC_VERSION} on Rocky 8" + echo " -h Show this help" + exit 0 +} + +CI_MODE=false +START_MDB=false +NO_CLEAN=false +BUILD_PACKAGES=false +INSTALL_DEPS=false +GCC_TOOLSET=false +UNIT_TESTS=false +OS="" + +while getopts "t:d:j:cpSnDRuh" opt; do + case $opt in + t) BUILD_TYPE="$OPTARG" ;; + d) OS="$OPTARG" ;; + j) CPUS="$OPTARG" ;; + c) CI_MODE=true ;; + p) BUILD_PACKAGES=true ;; + S) START_MDB=true ;; + n) NO_CLEAN=true ;; + D) INSTALL_DEPS=true ;; + R) GCC_TOOLSET=true ;; + u) UNIT_TESTS=true ;; + h) usage ;; + *) usage ;; + esac +done + +if [[ !

MariaDB uses per-charset collations based on UCA (Unicode Collation Algorithm) weight tables at specific Unicode versions. DuckDB stores all strings as UTF-8 internally and provides collation via two mechanisms: + +- **Built-in collations** — `NOCASE` (applies `lower()`), `NOACCENT` (strips diacritics), `NFC` (Unicode normalization). These are combinable: `NOCASE.NOACCENT`. +- **ICU locale collations** (from the ICU extension) — one per ICU locale (e.g. `de`, `en_us`, `fr`, `zh`). These use proper UCA via ICU but are not combinable with the built-in collations. + +Additionally, DuckDB registers `icu_noaccent` with the ICU tag `und-u-ks-level1-kc-true` (primary strength + case level), providing accent-insensitive, case-insensitive comparison via the full UCA algorithm. + +## Current Mapping + +The mapping is implemented in `duckdb_charset_collation.cc` (`get_duckdb_collation()`). It is applied in two places: + +1. **DDL** (`ddl_convertor.cc`) — VARCHAR columns get `COLLATE ` appended based on the column's `CHARSET_INFO`. +2. **Session context** (`duckdb_context.cc`) — each DuckDB connection's `default_collation` is set from the MariaDB session's `collation_connection`. + +### Supported charsets + +Only `utf8mb3`, `utf8mb4`, and `ascii` charsets are mapped to ICU-aware collations. All other charsets (e.g. `latin1`, `cp1251`) fall back to `POSIX` (binary comparison) because DuckDB cannot replicate their byte-level sorting rules. + +### Mapping table + +The mapping uses `CHARSET_INFO` flags — specifically `MY_CS_BINSORT`, `MY_CS_LOWER_SORT`, and `levels_for_order` bits — to determine the collation behavior. + +| MariaDB collation type | `levels_for_order` bits | DuckDB collation | Example MariaDB collation | +|---|---|---|---| +| `_bin` | (binsort flag) | `POSIX` | `utf8mb4_bin` | +| `_ai_ci` | primary only | `NOCASE.NOACCENT` | `utf8mb4_general_ci`, `utf8mb4_0900_ai_ci` | +| `_as_ci` | primary + secondary | `NOCASE` | `utf8mb4_0900_as_ci` | +| `_as_cs` | primary + secondary + tertiary | `POSIX` | `utf8mb4_0900_as_cs` | +| `_tolower_ci` | (lower_sort flag) | `NOCASE` | `utf8mb3_tolower_ci` | +| Non-UTF8 charset | — | `POSIX` | `latin1_swedish_ci` | + +### Constants + +Defined in `duckdb_charset_collation.h`: + +``` +COLLATION_BINARY = "POSIX" +COLLATION_NOCASE = "NOCASE" +COLLATION_NOCASE_NOACCENT = "NOCASE.NOACCENT" +``` + +`POSIX` is used instead of `binary` because `binary` is a reserved keyword in DuckDB. + +## Known Gaps + +### 1. Built-in `NOCASE` vs UCA case folding + +DuckDB's `NOCASE` applies `lower()` — simple Unicode case folding. MariaDB's UCA-based `_ci` collations use weight tables that handle complex cases (e.g. `ß` = `ss` in German, `İ` ≠ `I` in Turkish). This means comparison results can differ for non-ASCII characters. + +### 2. Built-in `NOACCENT` vs UCA accent handling + +DuckDB's `NOACCENT` uses `strip_accents()` which removes combining diacritical marks. MariaDB's `_ai` collations use UCA primary weights which may group characters differently (e.g. ligatures like `æ`). + +### 3. No `_as_cs` UCA equivalent + +MariaDB's `_as_cs` collations use full UCA tertiary weights for ordering. DuckDB's `POSIX` (binary) preserves case and accent sensitivity but produces a different sort order — it sorts by UTF-8 byte values, not UCA weights. This affects `ORDER BY` results. + +### 4. Non-UTF8 charsets lose collation semantics + +Any charset other than `utf8mb3`/`utf8mb4`/`ascii` is mapped to binary comparison. MariaDB's `latin1_swedish_ci` ordering (which treats `ä` = `a`, `ö` = `o`, etc.) is lost. + +## Possible Improvements + +### Use ICU locale collations for better UCA fidelity + +DuckDB's ICU extension registers collations for all available ICU locales. The relevant ICU collation tags for MariaDB equivalence are: + +| UCA behavior | ICU tag | DuckDB collation | +|---|---|---| +| accent-insensitive, case-insensitive (`_ai_ci`) | `und-u-ks-level1-kc-true` | `icu_noaccent` (already registered) | +| accent-sensitive, case-insensitive (`_as_ci`) | `und-u-ks-level2` | Not yet registered | +| accent-sensitive, case-sensitive (`_as_cs`) | `und-u-ks-level3` | Not yet registered | + +Registering `und-u-ks-level2` and `und-u-ks-level3` as custom DuckDB collations and mapping to them would provide much closer UCA equivalence for UTF-8 collations. + +### Register MariaDB-named collations + +An alternative approach is to register collations with MariaDB-compatible names (e.g. `utf8mb4_0900_ai_ci`) that delegate to the corresponding ICU collator.

This is why most implicit aliases pass but keyword aliases fail. | + +Reproductions (against any DuckDB-engine table `t`): + +```sql +SELECT JSON_OBJECT("k", 1) FROM t; -- Binder Error: column "k" not found +SELECT JSON_OBJECT('k', 1) FROM t; -- OK +SELECT col name FROM t; -- Parser Error at "name" +SELECT col AS name FROM t; -- OK +``` + +**Fix direction**: in `ha_duckdb_pushdown.cc`, convert double-quoted string literals to single-quoted form and quote (or `AS`-prefix) aliases that are DuckDB reserved keywords.

DuckDB does not support some interval unit such as SECOND_MICROSECOND, MINUTE_MICROSECOND, MINUTE_SECOND, etc. +# 5. DuckDB does not supoort compound expression unit, such as 'interval -1 day'. +# 6. [Partially Solved]Duckdb does not support week format, which will affect week(), yearweek(), str_to_date(), date_format() functions. +# 7. [Partially Solved] For a time type field, when implicitly converted to TIMESTAMP, MySQL will be current_date + time, while duckdb will be 1970-01-01 + time or cannot convert. +# 8. [Solved] For CURRENT_TIME(), CURRENT_TIMESTAMP(), CURTIME(), LOCALTIME(), LOCALTIMESTAMP(), NOW(), UTC_TIME(), UTC_TIMESTAMP(), the fsp argument is not support. +# 9. MySQL accepts NULL as function input but DuckDB does not. +# The above scenarios cannot guarantee compatibility and therefore will not appear in this test case. + +CREATE DATABASE test_duckdb; +USE test_duckdb; +CREATE TABLE t (id INT PRIMARY KEY) ENGINE = DuckDB; +INSERT INTO t VALUES (1); + +--echo --------------------------- +--echo 1.
