Does it support filtering though?

Edit: post filtering only

I don't understand how people are efficiently implementing tenant/user/permission scopes with these indexes.

Partitioning is the easy bit I think, and falls out naturally from Postgres.

But how are people doing recency biasing with vector databases?

All of our approaches are either expensive or super hacky.

Checks notes, one dayabase per client, per user, per project ... etc

LanceDB supports push down and list/array membership through DataFusion.

Multi-column indexes for multi-tenant tables is planned for a future release.
