AI Summary
This release improves performance and stability by removing full sync steps during graph loading and fixing crashes in replica nodes caused by data divergence.
Key Highlights
- Fixed replica SIGSEGV crash when UPDATE_EDGE/UPDATE_NODE diverges
- Improved RDB loading performance by removing full sync from decoder
- Added public APIs Graph_EncodingVersion and Graph_GetDecoder for external modules
New Features
- New public APIs for graph encoding versioning and decoding
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
