Two consecutive transactions from the same client could be executed over two different connections. A connection is only assigned to the client for the duration of a transaction. This is the suggested option for serverless functions. Afterward, the connection is returned back to the pool.Īll PostgreSQL features can be used with this option. When a new client connects, a connection is assigned to the client until it disconnects. Pgbounce provides several Pool Modes, each handling connections differently: Session When the client transaction or session is completed the connection is returned to the pool and is free to be used by another client. When a client makes a request, PgBouncer "allocates" an available connection to the client. Supabase uses PgBouncer for connection pooling. You can obtain your connection info and Server root certificate from your application's dashboard:Ī "connection pool" is a system (external to Postgres) which manages connections, rather than PostgreSQL's native system. 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.Ĭheck out the Github repository. To use Supavisor contact support and we will expose the connection string in your project dashboard. It won't require any application changes to switch from PgBouncer to Supavisor. We're building compatibility with PgBouncer. 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 highly available cluster not on your database. Supavisor is a new connection pooler by Supabase. Find your Connection Info and Connection String.You can find the connection pool config in the Database settings inside the dashboard: For example, if you are using Prisma, Drizzle, Kysely, or anything deployed to a Serverless environment (AWS Lambdas or Edge Functions). A connection pooler is useful for managing a large number of temporary connections. Direct connections are on port 5432.Įvery Supabase project comes with PgBouncer for connection pooling. You can find the connection string in the Database settings inside the dashboard: You can connect to the database using any tool which supports Postgres. Realtime: listen to database changes over websockets.Įvery Supabase project provides a full Postgres database.
