Change Summary
Using
asyncio.gather
with SQLAlchemy may result some unexpected errors: sqlalchemy/sqlalchemy#9312. We should avoid using it.Also even
asyncio.gather
is still expensive because eachfor loop
iteration sends a separated query to the database. Replaced it withconnection_id IN (...)
clause, reducing to just one database request.Related issue number
