Release date: September 28, 2026
MatrixOne version: v4.2.5
MatrixOne 4.2.5 is a patch release on top of 4.2.4, improving multi-file data loading, reducing memory-management overhead, and fixing checkpoint filtering, log recovery, and Proxy connection deadlines.
Key Improvements
Data Loading
- Multi-File and Compressed Sources: Support file patterns for LOAD DATA and external tables, parallelize multi-file CSV reads by whole file, and add zip/zstd source support.
Memory Efficiency
- Lower Allocation and Teardown Overhead: Use compact bitsets for multi-term read filtering and narrow on-heap ownership scans during memory-pool teardown.
Key Bug Fixes
Correctness and Reliability
- Multi-Scope Loading: Preserve rows when a TP-classified plan contains multiple scopes.
- Statistics Refresh: Filter checkpoint change ranges against the requested time window, avoiding repeated statistics recalculation for historical table changes.
- Log-Service Recovery: Include Dragonboat torn-tail repair and failure-safe log rebuilding to address the tan CRC-mismatch startup failure after a crash.
- Proxy Long-Lived Connections: Clear phase-owned read deadlines after handshake, migration, and cached-backend reuse so active connections do not inherit an expired control-phase deadline.
