Addresses concern (3) from #17001
As called out in #17001. The async planner has differnet behavior in
fillQueue(Snapshot readFrom)andfillQueue(fromOffset, toOffset)with regard to the start snapshot. Specifically,fillQueue(fromOffset, toOffset)includes the first snapshot even it is a replacement commit. This PR aligns the behavior to consistnetly drop the replacement commit by calling the same filtering logic that is already used infillQueue(Snapshot readFrom).Added test illustrates the change in the behavior for the async planner: wihtout the change in the
fillQueue, the assertion will objserve the rows not only from the second batch, but also from the first batch added before the timestamp passed into the stream initialization.As this change can be fairly isolated from other issues in #17001, creating a dedicated PR just for this one.
Follow ups
This change addresses the behavior in spark 3.5; can downport to spark 4.0 and 3.5 as a next change.
