Upgrading?
AI Summary
Enhances replica stability, speeds up graph loading, and exposes new public APIs for external modules.
Key Highlights
- Replicas no longer crash on divergence; they now trigger a full resync instead of crashing with SIGSEGV.
- Graph loading is significantly faster due to incremental delta-matrix reconstruction during RDB decoding.
- New public APIs allow external modules to stamp dumps with encoding versions and select matching decoders.
New Features
- Export of `Graph_EncodingVersion` and `Graph_GetDecoder` APIs
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
