MYSQL connections

[dkikalis]

Hello,
If I use node-red-node-mysql to connect to a database the lambda returns the data as expected but the lambda stays running until the maximum execution time expires or the connection drops. This could be quite expensive as I need quite a large lambda to get the required performance. Have you got any tips?

Hello,
It looks the cause that mysql module uses event loop. Lambda waits for empty event loop.
