Description
Expected Behavior
The user can throttle the initial polling with a fixed delay when split is set to the default value of true.
This would be similar to the spring.cloud.stream.poller.fixed-delay property available when split is set to false.
Current Behavior
The initial polling is repeated until there are no more results returned without any kind of pausing which can overwhelm downstream processing when there are many thousands of rows returned by the query.
Context
The current workaround is to always set split to false.

Research direction
Start at the JDBC supplier's initial polling path when split is true, and compare it with the spring.cloud.stream.poller.fixed-delay behavior used when split is false. Done means repeated initial polling can honor a fixed delay while split remains true and no longer overwhelms downstream processing.
