Upgrading?
AI Summary
This release addresses critical stability issues by fixing SIGSEGV crashes caused by divergent references in replication. It also enhances performance by optimizing RDB decoding and introduces new public APIs for graph serialization.
Key Highlights
- Fix for replica SIGSEGV on UPDATE_EDGE/UPDATE_NODE divergence
- Improved RDB decoding performance via incremental matrix building
- New public APIs (Graph_EncodingVersion, Graph_GetDecoder) for graph serialization
New Features
- New public APIs for graph serialization (Graph_EncodingVersion, Graph_GetDecoder)
Full Release Notes
## What's Changed ### Bug Fixes * fix(effects): stop replica SIGSEGV on UPDATE_EDGE/UPDATE_NODE divergence - replicas no longer crash when an effect references a node or edge that no longer exists locally; the mismatch is now detected and triggers a full resync instead (#2581) ### Performance * remove full sync from decoder - transpose matrices are rebuilt incrementally as delta-matrix components are set during RDB decoding instead of forcing a full sync at the end, speeding up loading of persisted graphs (#2584) ### Improvements * serializers: export Graph_EncodingVersion and Graph_GetDecoder - new public APIs let external modules (e.g. graph-offloading) stamp dumps with their encoding version and select the matching decoder on load (#2552) **Full Changelog**: https://github.com/FalkorDB/FalkorDB/compare/v4.20.3...v4.20.4
