the {adapter} adapter cannot push {work}, so...

Warnings reference › source.pushdown.residual.*.*

Identifier

source.pushdown.residual.*.*

Raised by

The grid (core)

Since

1.12.1

What happened

Part of the query could not be expressed to the engine, so the grid asks for every matching row and finishes the work locally. The answer is right; the cost is the full download on every query. The key carries the adapter and exactly which work was left over, so two different shortfalls are two lines.

The fix

Widen the adapter to handle the named work, or narrow the query to what it can push. lastPlan().unpushed names it programmatically.
