Checks several vector keys in one collection and returns positional boolean status values. The response preserves the input order.

Itemwise batches return one positional item result per input item. The outer batch status summarizes whether all, some, or none of the items succeeded.

Examples

Check existence for many keys at once.

CLI

$ strata vector collection create docs 3 cosine
$ strata command run --command-json '{"collection":"docs","entries":[{"key":"a","vector":[1.0,0.0,0.0]}],"type":"vector_batch_upsert"}'
$ strata command run --command-json '{"collection":"docs","keys":["a","missing"],"type":"vector_batch_exists"}'

Wire

{"collection":"docs","dimension":3,"metric":"cosine","type":"vector_create_collection"}
{"collection":"docs","entries":[{"key":"a","vector":[1.0,0.0,0.0]}],"type":"vector_batch_upsert"}
{"collection":"docs","keys":["a","missing"],"type":"vector_batch_exists"}

Parameters

Name	Type	Required	Description
collection	string	yes	Collection name.
keys	string[]	yes	Vector keys to check.

Plus the optional scope: branch and space (default to the session branch and the "default" space).

Returns

BatchResult<BatchExistsPresence>.
