   @ad1happy2go IIUC, here are the options:
   
   - Leverage `REPLICA IDENTITY FULL` which has some downsides as mentioned in 
PG documentation and the article I shared in my earlier comment.
   - Leverage `REPLICA IDENTITY USING <index>` as long as the field upon which 
we'd like to partition has a UNIQUE index in the upstream PG Table.
   - Leverage the `GLOBAL_BLOOM` indexing you mentioned.
   
   Are there any downsides or trade-offs with the `GLOBAL_BLOOM` index type I 
should keep in mind? I'll try this approach as well on my end **without** 
`REPLICA IDENTITY FULL` and see how it goes. Thanks a lot!
