RelationalSnapshotChangeEventSource.determineSnapshotSelect(RelationalSnapshotChangeEventSource.RelationalSnapshotContext<P,O> snapshotContext,
TableId tableId) |
Returns a valid query string for the specified table, either given by the user via snapshot select overrides or
defaulting to a statement provided by the DB-specific change event source.

RelationalSnapshotChangeEventSource.getAllTableIds(RelationalSnapshotChangeEventSource.RelationalSnapshotContext<P,O> snapshotContext) |
Returns all candidate tables; the current filter configuration will be applied to the result set, resulting in
the effective set of captured tables.
