Initial open source release Changelog

This library created to interact with Tarantool 2.11+, 3.x and all products on it's base like Tarantool DB, Tarantool Data Grid

Core Protocol Support

  • IPROTO Protocol: Full support for IPROTO protocol features including:
  • Tarantool Types, complete support for all tarantool types including:
  • Async Operations: Async request model using completable futures

Client APIs

  • IProto Client: Low-level API for tarantool protocol that follows the protocol as it is (call, eval, select, insert, ...)
  • Connection Management: Support for multiple Tarantool nodes, connection pools, and graceful shutdown
  • Box Client: High-level API for tarantool protocol that simplifies working with the protocol. Should use to work directly with Tarantool storage
  • Crud Client: High-level API for tarantool/crud operations with simplified interfaces to work with Tarantool cluster that supports tarantool/crud library
  • (experimental) TDG Client: client implementation for Tarantool Data Grid 1.x/2.x

Spring Data Integration

  • Multiple Spring Versions: Support for Spring Data 2.7.x, 3.1.x, 3.2.x, 3.3.x, 3.4.x with dedicated modules
  • Repository Support: Full repository functionality including findById, save, delete, existsById, count operations
  • Derived Queries: Support for derived query methods with keywords like findBy*, deleteBy*, existsBy*, countBy*
  • Composite Keys: Support for composite keys using @IdClass annotation
  • Custom Annotations: @Query annotation for proxying call/eval operations
  • Pagination: Supports Spring Data Pageable interfaces: Page, Pageable, Slice, Scroll API

Advanced Features

  • Schema Management: Online schema reload and support for space/index
  • Heartbeat & Health Checks: Support for heartbeats using IPROTO_PING requests with customizable ping functions to detect whether connected instance alive or not
  • Monitoring: Built-in metrics support with customizable metrics registry (Prometheus exporter)

Data Mapping & Serialization

  • Flexible Java Types Mapping: Java types be easily mapped to Tarantool via Jackson for msgpack. Implicitly by High-level clients or could use explicitly by low level clients.
  • POJO Mapping: Mapping between tarantool types and POJOs also by Jackson for msgpack
  • Object Operations: Object-based CRUD methods (insert_object, replace_object, upsert_object, etc.)
  • Nil Response Handling: NilErrorResponse class for handling nil responses in call/eval operations
  • Tuple Extensions: Support for MP_TUPLE extension type with format information

Load Balancing & Connection Management

  • Balancer Support: Round-robin balancers for distributing requests
  • Connection Pooling: Robust connection pooling with PoolEventListener support
  • Watchers: Enhanced watcher support with synchronization and error handling
  • Reconnection: Configurable reconnecting delay and connection timeout options

Testing & Development

  • Testcontainers: Dedicated testcontainers module
  • TDB2 Cluster Support: Simple realization of TDB2 cluster testcontainers
  • Configuration: Property-based, JavaConfig, and annotation-based configuration options

Security & Authentication

  • Authentication: Support CHAP-SHA1 and PAP-SHA256
  • Role-based Access: Support for super user roles in testcontainers configuration

Performance Optimizations

  • Encoding Efficiency: Optimized encoding with single messagepack packer per connection
  • Memory Management: Efficient serialization focusing only on user data
  • Thread Safety: Thread-safe implementations for concurrent operations

This comprehensive feature set makes the Tarantool Java SDK library a powerful tool for integrating Java applications with Tarantool databases, offering both low-level protocol access and high-level abstractions for common operations.
