Transactions with multiple statements are not allowed. Connections are returned to the pool after every statement. Some session-based Postgres features such as prepared statements are not available with this option. Two consecutive transactions from the same client could be executed over two different connections. A connection is 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 Postgres features can be used with this option. When a new client connects, a connection is assigned to the client until it disconnects. There are 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, the pooler "allocates" an available connection to the client. You can use their ORM to connect to your database.Ī "connection pool" is a system (external to Postgres) which manages Postgres connections. You can obtain your connection info and Server root certificate from your application's dashboard:ĭrizzle ORM is a TypeScript ORM for SQL databases designed with maximum type safety in mind. 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 Data APIs provide programmatic access and have built-in connection pooling.Find your Connection Info and Connection String.You can find the connection pool config in the Database settings inside the dashboard: A connection pooler is useful for managing a large number of temporary connections - for example, if you are using Prisma, Drizzle, Kysely, or anything deployed to a Serverless environment (AWS Lambdas or Edge Functions). Find your Connection Info and Connection String.Įvery Supabase project comes with a connection pooler for managing connections to your Postgres database.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.GraphQL: interact with your database through a GraphQL interface.REST: interact with your database through a REST interface.We provide several types of API to suit your preferences: These are the easiest way to get started if you are managing data (fetching, inserting, updating). Supabase provides auto-updating Data APIs. Connection pooling for scalable connections.Direct connections using the built-in Postgres connection system.Programmatic access using the Data APIs.ORDER BY "posts".Supabase provides several options for programmatically connecting to your Postgres database: The sql for the Post.last command is SELECT "posts".* FROM "posts" 5 ms ) COMMIT => # irb ( main ): 003 : 0 > Post. 0 ms ) INSERT INTO "posts" ( "title", "created_at", "updated_at" ) VALUES ( $1, $2, $3 ) RETURNING "id", , ] ( 26. 7 ms ) COMMIT => # irb ( main ): 002 : 0 > Post. 5 ms ) INSERT INTO "posts" ( "title", "created_at", "updated_at" ) VALUES ( $1, $2, $3 ) RETURNING "id", , ] ( 8. $ rails c Running via Spring preloader in process 3134 Loading development environment ( Rails 6.
