createPushdownSource needs an `adapter` with an `execute(query)` function.

Warnings reference › source.pushdown.adapter

Identifier

source.pushdown.adapter

Raised by

The grid (core)

Since

1.12.1

What happened

The pushdown source has nothing to push to. A remote source is still returned so the grid builds, and its fetch answers with no rows and a total of zero - the grid is permanently empty.

The fix

Pass an adapter with execute(query) and a capabilities declaration.

The smallest fix

createPushdownSource({ adapter: createDuckdbAdapter({ connection, from: 'orders' }) });
