sqlalchemy 和 asyncpg – 设置 postgres statement_timeout

Question

When doing

engine: AsyncEngine = create_async_engine(...)

and then

async with engine.connect() as conn:
    result: Result = await conn.execute(text("""..."""))

I would like to specify a timeout. Ideally I'd be able to set statement_timeout just for this one query execution. I am also fine with sqlalchemy doing the timeout and cancelling the query execution, but I can't find a way to set either.

Answer 1

create_async_engine(
            db_url, connect_args={"command_timeout": 28.0}
        )

use command_timeout in connect_args in seconds
