[1.0.20] - 2026-03-18

Added

  • Fabric plan cache: Added pkg/fabric/plan_cache.go and wired prepared-plan reuse for repeated multi-graph query shapes to reduce repeated planner work on cache misses.
  • Fabric/Cypher hot-path tracing: Added explicit hot-path trace plumbing (pkg/fabric/tracing.go, pkg/cypher/executor_hotpath_trace.go) to verify/lock optimization-path usage in integration tests.
  • Targeted index-seek regression coverage:
    • added explicit tests for MATCH ... WHERE <prop> IS NOT NULL ORDER BY <prop> LIMIT K index top-K behavior
    • added tests for indexed IN $param seek paths used by correlated Fabric APPLY batching
    • added constant-conjunct top-K matching coverage.
  • Planning docs expansion:
    • Added docs/plans/gpu-hnsw-construction-plan.md
    • Rewrote/expanded docs/plans/ui-enhancements.md to reflect current priorities.

Changed

  • Correlated join execution path hardening:
    • restored and stabilized correlated Fabric APPLY batched lookup hot paths across cloned executor contexts
    • improved trace propagation across USE-scoped executor clones so hot-path verification reflects real runtime routing.
  • Cypher/Fabric performance optimization pass:
    • reduced allocation-heavy branches in correlated APPLY processing
    • improved index-first routing for high-frequency MATCH shapes
    • refined indexed top-K and index-seek behavior for large-cardinality query paths.
  • Safe query cache behavior for remote targets:
    • tightened result cache gating so remote-constituent execution paths avoid unsafe/undesired local result caching.
  • UI base-path normalization:
    • normalized Vite/UI base-path handling to avoid trailing-slash concatenation issues and route/API join breakage.

Fixed

  • UNWIND map-row create/merge regression: Fixed Cypher UNWIND parameter handling where map-row create/merge flows could fail or route incorrectly under Fabric/composite execution.
  • BM25 deterministic lexical-seed stability: Fixed nondeterministic lexical seed selection in BM25 v2 paths and stabilized index drop/recreate guards.
  • Dropped-database search artifact cleanup: Fixed stale per-database persisted search artifacts surviving DROP DATABASE and being reloaded unexpectedly on recreate.
  • IS NOT NULL top-K matcher robustness: Fixed hot-path matcher to keep index top-K active when additional constant top-level AND predicates are present.

Tests

  • Added deterministic end-to-end/integration coverage for:
    • correlated Fabric APPLY joins (including 100k-scale profiling benchmark paths)
    • hot-path trace assertions (OuterIndexTopK, batched APPLY row path, scan-fallback guardrails)
    • indexed IN and indexed top-K MATCH execution branches
    • UNWIND property map regression scenarios.
  • Expanded storage schema/index tests around top-K ordering and cache invalidation behavior.

Documentation

  • Updated roadmap entries in README.md to reflect current planning state.
  • Refreshed UI enhancement planning doc with concrete structure and testability focus.
  • Added GPU-assisted HNSW construction plan doc with persistence-compatibility constraints.

Technical Details

  • Range covered: v1.0.19..HEAD
  • Commits in range: 15 (non-merge)
  • Repository delta: 53 files changed, +5,884 / -779 lines
  • Non-test surface changed: 36 files
  • Primary focus areas: Fabric/Cypher correlated-join performance, index-driven hot paths, cache safety for remote constituents, deterministic search behavior, and roadmap/planning documentation updates.
