AI Summary
This release addresses a critical crash in replicas when effects reference non-existent nodes or edges, implements incremental matrix rebuilding for faster RDB decoding, and exposes new public APIs for graph encoding versions.
Key Highlights
- Fix replica SIGSEGV on UPDATE_EDGE/UPDATE_NODE divergence
- Performance improvement: incremental matrix rebuilding during RDB decoding
- New public APIs: Graph_EncodingVersion and Graph_GetDecoder
New Features
- Export Graph_EncodingVersion and Graph_GetDecoder APIs for external modules
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
