Couchbase Server 7.2+ introduces vector search indexes that must be defined with exact dimension specifications matching the query vectors.

Log entries report 'vector dimension mismatch' when the vector dimension of the indexed documents differs from the dimension declared in the CREATE INDEX ... WITH {"type":"vector"} clause, and memory pressure can trigger indexer termination.

What configuration steps guarantee that the declared vector dimension aligns with the actual document vectors? How can the indexer.memoryQuota setting be validated to prevent memory‑related indexer kills?
