Using PGBouncer with CockroachDB

PGBouncer is a lightweight connection pooler for PostgreSQL. CockroachDB is a cloud-native SQL database for building global, scalable cloud services that survive disasters.

CockroachDB is PostgreSQL wire compatible database, which means it aims to have tight compatibility with the PG ecosystem. Today, we're going to wire PGBouncer to work with CockroachDB. This article is meant to scratch the surface of possibilities unblocked by PGBouncer with CockroachDB and not meant to be an in-depth overview. We're currently researching this topic and will follow up with official docs on proper architecture and sizing of PGBouncer and CockroachDB.
