heroku-buildpack-pgbouncer
A Heroku buildpack that installs and runs PgBouncer in a dyno alongside your app for PostgreSQL connection pooling.
What is heroku-buildpack-pgbouncer?
Heroku Buildpack PgBouncer is a Heroku buildpack that installs and runs PgBouncer within a dyno alongside an application. It provides PostgreSQL connection pooling, allowing multiple workers in a dyno to share a single database connection to avoid connection limits and reduce memory usage on the database server. It is designed to be used in conjunction with other buildpacks, such as language-specific ones, to enhance database performance on Heroku.
Heroku users running applications with multiple workers per dyno (e.g., Ruby on Rails apps with Unicorn) that need to optimize PostgreSQL connection usage and avoid database connection limits.
Developers choose this buildpack because it seamlessly integrates PgBouncer into Heroku dynos without requiring external services, reduces PostgreSQL connection overhead, and is configurable for various pooling scenarios and multiple databases.
