Hi,
Yes, he will need to do something to meet his goal of both a 100k TPS
and have older archives online. He could also use something like
postgres_fdw to have the archives on a seperate server completely.

Thanks for the suggestions guys !
After checking i am thinking about following approach:
1. Create a FS on a separate drive on the server with VDO
2. Create a tablespace on FS created above for storing the historical/less update intensive data
3. Other tablespaces remain on non compressed FS
4. Use table partitioning and create the tables in tablespace created in step 2.
- will this complicate the DB design? In terms of replication, backup and restores
- Can this give optimum performance.
Let me know your views !
Thank You !
