2. gridsql

which is a better way to use sharding

also is it possibl

Answer 1

Best practice to achieve PostgreSQL cluster is using:

1. PostgreSQL Partition (range or list).
2. Combine PostgreSQL partition and tablespace in several SSD.
3. PostgreSQL FDW extension.

Alternative: Postgres-XL

For Sharding (loadbalance) you can use:

1. Postgres-BDR
2. Postgres-X2

Note:

Cluster purpose is contain big dataset and mostly for data warehouse.

Sharding purpose is for loadbalance and mostly used for high-transaction database.

** WARNING **

avoid pgpool because too many overhead that will lead issue in the future.

Hope this answer will help you in future development.
