   Hi @stevenzwu , about `TableScan.appendsBetween`, we can limit the snapshot 
number of scan, even scan only one at a time. Because 
`TableScan.appendsBetween` seems to be just a combination of single incremental 
snapshots, we can handle only one snapshot at a time.
   
   - For FLIP-27 Source, it is easy to do, because tasks came to ask for 
splits, the only problem is that within the coordinator, the coordinator can 
completely control how the splits are generated.
   - For the old API, the downstream reading operator should has a max split 
queue size to back pressure the Enumerator. And do above thing.
