Curious about the "outside of the database" index generation part. Is this index WAL-protected eventually?

- diqi 3y agoYes it is WAL protected: the advantage of external indexing is that the HNSW graph is being constructed externally on multiple cores instead on a single core inside the Postgres process. But eventually the graph is being parsed and processed inside Postgres with all the necessary WAL logs for blocks.
