   > > I think the redesign of dedup makes sense but it'll be a much larger and 
involved effort, and unlikely for @raghavgautam to take. I think it makes sense 
to start a separate effort of dedup V2, but in the meantime it's fine for the 
community to add features and make improvements over V1, assuming it'll take 
some time for V2 to be ready.
   > 
   > My concern for the current dedup implementation is that it is not 
maintained properly (not production ready), and the bugfixes for upsert is not 
added to dedup. If we decide to keep V1, we want to first apply all the changes 
to upsert to dedup as well.
   
   This sounds like a bigger problem that dedup is not ready for the community 
but we released it. I don't see any warning in [Pinot 
doc](https://docs.pinot.apache.org/basics/data-import/dedup)...
   
   I think we either maintain V1, or not advocate its use (e.g. mark it as 
experimental, or remove it). @kishoreg @icefury71 wdyt?
