What does this PR do?

Relationship loading batches up to 5,000 IDs even when the connection permits fewer query values. A document with 501 related IDs therefore fails to load with a 500-value limit.

Use the configured maxQueryValues for all five relationship query batches and remove the redundant RELATION_QUERY_CHUNK_SIZE constant. Keep the existing max(1, ...) guard used by other batch queries. Validation of caller-supplied queries remains unchanged.

A configured limit above 5,000 also permits larger relationship batches. This follows the existing ID-lookup batching policy; 52b189bd adopted it for other lookups and left these five relationship paths for a follow-up. The default limit remains 5,000.

Test Plan

  • Nine regression cases cover all relationship types in both directions, plus a single parent exceeding the limit. Explicit oversized queries must throw QueryException.
  • PostgreSQL, SQLite, and shared-table PostgreSQL: 27 tests / 129 assertions passed after the review changes. All nine PostgreSQL cases were confirmed to fail without the fix.
  • PHP syntax, Pint, and diff checks pass. CI will rerun on the updated commit.

Appwrite adoption requires a library release and dependency update. The HTTP regression is appwrite/appwrite#13610.

Summary by CodeRabbit

  • Bug Fixes

    • Relationship lookups now respect the configured maximum number of query values per request.
    • Related records can be fetched reliably without exceeding query value limits, including many-to-many relationships.
  • Tests

    • Added coverage for relationship queries under configured value limits.
    • Confirmed that explicit queries exceeding the limit continue to return the expected error.

RetriggerConfidence Score: 5/5

The PR appears safe to merge, with no remaining actionable correctness, security, or repository-rule issues.

Summary

  • Uses max(1, $this->maxQueryValues) consistently for relationship batches.
  • Adds end-to-end coverage for every relationship type and direction, including a parent whose related-document count exceeds the configured limit.
  • Verifies that caller-supplied queries exceeding the configured limit remain rejected.

I think the const RELATION_QUERY_CHUNK_SIZE is useless , will never use it ..
We can always use $this->maxQueryValues

Consider extracting the repeated chunked-find pattern.

The five relationship batch loops repeat the same three-line shape: array_chunk($ids, \max(1, $this->maxQueryValues)), then a find() (or skipRelationships(fn () => $this->find(...))) call with Query::equal(...) plus Query::limit(PHP_INT_MAX), then \array_push($result, ...$chunkDocs). Extract a small private helper, for example findChunkedByValues(string $collectionId, string $attribute, array $values, array $extraQueries = [], bool $skipRelationships = false): array, and call it from all five sites. This removes duplicated logic and centralizes any future change to chunking behavior (for example, retry or backoff) in one place.
