In-memory vector store for RAG

Usage and specifics

For insert, supply documentsSource and vectorsSource, with one equal-dimension vector per document. For query, supply queryVectorSource; for delete, supply a nonempty idsSource list. Results are in matches. The simple store stays in execution data and storeSource reuses its output; external storage retains an index across runs.

Technical type : ai_simple_vector_store. Runtime : nodulz.

Credentials and prerequisites

This node defines no dedicated external credential. Remote sources or execution targets may still need their own access credentials.

See the credentials guide if a remote source or execution target requires access.

Parameters

Names below are technical keys. Defaults are not a ready-to-run configuration: complete fields required by your operation. Paths containing [] describe list items; some fields depend on the selected mode.

Parameter	Type	Default	Values / limits
`operation`	`enum`	`"insert"`	`insert`, `query`, `delete`
`credentialId`	`string`	-	-
`serviceInstanceId`	`string`	-	-
`connectionSource`	`enum`	`"credential"`	`credential`, `service`
`indexName`	`string`	`""`	-
`namespace`	`string`	`""`	-
`documentsSource`	`string`	`""`	-
`vectorsSource`	`string`	`""`	-
`query`	`string`	`""`	-
`queryVectorSource`	`string`	`""`	-
`idsSource`	`string`	`""`	-
`topK`	`number`	`4`	-; ≥ 1, ≤ 1000
`storeSource`	`string`	`""`	-

Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

json

}

Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
