Expand description

A mock ReferenceTableSource for testing.

Configurable queues of snapshot and change batches. Tracks lifecycle flags (snapshot_complete, restored, closed) for test assertions.

Fields§

§snapshot_batches: VecDeque<RecordBatch>

Snapshot batches to deliver (drained in order).

§change_batches: VecDeque<RecordBatch>

Change batches to deliver after snapshot (drained in order).

§snapshot_complete: bool

Set to true once all snapshot batches have been delivered.

§restored: bool

Set to true after restore is called.

§closed: bool

Set to true after close is called.

§mock_checkpoint: SourceCheckpoint

The checkpoint returned by checkpoint.
