Signal tables
A signal table must be configured in the source database to enable on-demand snapshots. This table is tracked by the connector and automatically triggers snapshots when it receives a signal.
Note that:
- A signal table should be pipeline-specific to avoid accidental overlap of snapshot executions.
- The connection details provided for the source must have write permissions to the signal table.
- The pipeline will insert a row into this table to trigger a snapshot.
- The table should be created with the correct structure.
- Supplemental logging must be enabled for the signal table.
