Decision

What the current evidence supports

Agent-assisted assessment · independently reviewed · 2026-09-30

Pilot for analytical workloads that benefit from combining vector retrieval and SQL.

Why
The 25.8 family has GA indexing and independent integration evidence, but performance depends on cache sizing, table parts, filters and update patterns.
Next
Test the chosen 25.8 patch with representative embeddings, filtered recall, concurrent ingestion, merges and cold-cache latency before production rollout.

Constraints

Blockers

  • HNSW cache eviction can sharply increase latency.
  • Filtered recall and quantization require workload-specific validation.
  • Frequent updates and deletes can create costly mutation workloads.
  • Limited independent sustained-production evidence for the exact 25.8 scope.
