Manages a pool of connections based several builtin strategies.

conn_pool

Manages a pool of connections.

Shared pool

Creating a pool

Pool requires an instance of ConnectionManager to open and close connections. In this article, we will use PostgresManager for demonstration purposes.

final pool = SharedPool(PostgresManager('exampleDB'), minSize: 5, maxSize: 10);

Getting connection

Connection<PostgreSQLConnection> conn = await pool.get();
PostgreSQLConnection db = conn.connection;
await db.execute(
        "CREATE TABLE posts (id SERIAL PRIMARY KEY, name VARCHAR(255), age INT);");

Releasing the connection to the pool

await conn.release();
