   @n3nash Thank you for getting back to me. Let me know if you need extra 
manpower to help fix `MergeOnReadIncrementalRelation`. :)
   
   As for the second issue, thank you for providing extra insights into this, 
and I understand your point that if the checkpoint has not changed; once there 
is another "latest" change, it will surely pull that out for me incrementally 
given it will be on the active timeline again. However, what if the 
"intermediate" changes are supposed to the "last" changes to the records, and 
the archival puts them in an _invisible_ state? ๐Ÿค”And will the checkpoint stay 
the same all the time? 
   Right now, it seems like the relationship between archived/active timeline 
and incremental pull _requires_ the user to have a carefully controlled 
incremental pull interval to get all updates before it gets archived, and I 
wonder if that's easy to achieve? Just throwing a bunch of my thoughts and 
concerns, and please do let me know what you find regarding commit time 
provided is way in the past and not in the hudi timeline. ๐Ÿ˜…
