Schema-based sharding for PostgreSQL

Citus 12 adds a new and easy way to scale your Postgres database—schema-based sharding. Unlike row-based sharding, where tables are distributed based on the value in the distribution column, schema-based sharding transparently shards your database by schema name. This new model enables new workloads, that were either hard or impossible to achieve with row-based sharding, most notably microservices and non-homogenous per tenant schemas. So now, you may have a choice based upon the needs of your application—row-based sharding or schema-based sharding.

In addition to schema-based sharding Citus 12 also includes:

  • Sampling in tenant monitoring which improves performance
  • A change to the default rebalancing strategy which is now "by_disk_size"
  • Improved MERGE support
