More...

0.5.0 #

  • Initial public release
  • SyncEngine: core interface for CRDT merge operations, hydration streams, and sync lifecycle management
  • EngineParams / StandardSyncEngine: concrete engine implementation wired to a Storage and a list of Backend instances
  • Two-pass sync pipeline: fetch-and-merge phase followed by upload phase, with typed pipeline events (ShardRefEvent, MergedResourceEvent, UploadedResourceEvent, etc.)
  • Three storage layout strategies: FilePerResource (one file per RDF resource), ShardDataset (packed shards, configurable count), SingleFile (everything in one file)
  • SyncManager / StandardSyncManager: sync triggering, auto-sync scheduling, and status streaming (SyncState, SyncStatus)
  • Storage interface with InMemoryStorage for testing; Drift-backed implementation in locorda_drift
  • Backend / PipelineBackend: pluggable remote storage interface with upload/download result types and auth-retry support
  • Hybrid Logical Clock (HLC) based CRDT merge: LWW-Register, OR-Set, FWW-Register and Immutable strategies
  • HydrationBatch: typed batch of graph updates and deletion IDs delivered to the application on each sync cycle
  • SyncEngineConfig: IRI-level configuration for resources, index types and root resource fetch policies
  • IriTranslator hierarchy for local ↔ remote IRI mapping
  • Index types: FullIndexData (monolithic) and GroupIndexData (partitioned by regex key) with RootResourceFetchPolicy (onRequest / prefetch)
