Reads several vector keys and returns positional item results. Each item records found or missing state.

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

Read many vectors 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]},{"key":"b","vector":[0.0,1.0,0.0]}],"type":"vector_batch_upsert"}'
$ strata command run --command-json '{"collection":"docs","keys":["a","b"],"type":"vector_batch_get"}'

Wire

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

Parameters

Name	Type	Required	Description
collection	string	yes	Collection name.
keys	string[]	yes	Keys to read.

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

Returns

BatchResult<Maybe<VectorVersionedData>>.
