Returns a boolean status for one vector key without loading the embedding.

Status commands return a scalar or compact status payload and do not mutate database state.

Examples

Check whether a key exists in a collection.

CLI

$ strata vector collection create docs 3 cosine
$ strata vector upsert docs a [1.0,0.0,0.0]
$ strata vector exists docs a
$ strata vector exists docs absent

Wire

{"collection":"docs","dimension":3,"metric":"cosine","type":"vector_create_collection"}
{"collection":"docs","key":"a","type":"vector_upsert","vector":[1.0,0.0,0.0]}
{"collection":"docs","key":"a","type":"vector_exists"}
{"collection":"docs","key":"absent","type":"vector_exists"}

Parameters

Name	Type	Required	Description
collection	string	yes	Collection name.
key	string	yes	Vector key.

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

Returns

StatusValue<bool>.
