increase insert into local table from remote oracle table preformance - Mailing list pgsql-admin

Hi,

I'm using postgresql v10.4. I have a local partitioned table (by range - data, every day has its own table). I'm using the oracle_fdw extension to bring data from the oracle partitioned table into my local postgresql (insert into local select * from remote_oracle). Currently, I dont have any indexes on the postgresql`s table. It takes me 10 hours to copy 200G over the network and it is very slow.

Any recommandations what can I change or improve ?

Thanks , Mariel.
