![]() You should connect to your database using SSL wherever possible, to prevent snooping and man-in-the-middle attacks. a serverless environment)? If yes, use a connection pool. Are you connecting to your database and then disconnecting immediately (e.g.Are you connecting to a database and maintaining a connection? If yes, use a direct connection.You can use these simple questions to determine which connection method to use: Why would you use a connection pool? Primarily because the way that Postgres handles connections isn't very scalable for a large number of temporary connections. You should use this for serverless functions and tools which disconnect from the database frequently, like Prisma, Drizzle, Kysely, etc. A "connection pooler" is a tool which keeps connections "alive".You should use this for tools which are always alive - usually installed on a long-running server, like Node.js, Ruby, Python, etc. A "direct connection" is Postgres' native connection system.We recommend using these wherever possible. You can use these for all browser and application interactions. The Serverless APIs provide programmatic access and have built-in connection pooling.Supavisor is open source and compatible with any Postgres deployment. ![]() The PgBouncer connection string will also be similarly inaccessible from the dashboard. Note that while PgBouncer remains accessible for use, it will no longer be available for configuration from the dashboard. When a project is switched from PgBouncer to Supavisor, the appropriate connection string will be made available under the Connection Pooling section on Database settings. We're building compatibility with PgBouncer, and application changes will not be required to switch from PgBouncer to Supavisor. ![]() It also makes connecting to Postgres in a serverless environment much easier. This can free up some CPU cycles for your database to use for queries. It can provide a more scalable connection pool than PgBouncer, and runs on a high-availability cluster segregated from your database. Supavisor is a new connection pooler by Supabase. Otherwise, update your applications to use Supavisor which will continue to support IPv4 connections. No changes are required if your network supports communicating via IPv6. Additionally, your Supabase database domain (db.) will start resolving to an IPv6 address. On 15th January 2024 PgBouncer will be disabled. Supavisor is available on all new and existing projects. PgBouncer is being deprecated in favor of Supavisor.
