Collections


A collection is an group of vector records. Records can be added to or updated in a collection. Collections can be queried at any time, but should be indexed for scalable query performance.

Each vector record has the form:

1
2
3
4
5
Record ( id: String vec: Numeric[] metadata: JSON)

For example:

1
("vec1", [0.1, 0.2, 0.3], {"year": 1990})

Underneath every vecs collection is a Postgres table

1
2
3
4
5
create table <collection_name> ( id string primary key, vec vector(<dimension>), metadata jsonb)

where rows in the table map 1:1 with vecs vector records.

It is safe to select collection tables from outside the vecs client but issuing DDL is not recommended.
