Review Comment:
The
`snapshotLoadQuerySplitter.get().getNextCheckpointWithPredicates(snapshot,
queryContext)` can return a different end completion time than what
`queryContext` has, because of additional filtering, so we need to update the
instant time list for `IN` predicate for the snapshot query.
