Description:

Hey everyone,

I have an application that uses a Redis connection created from a connection from a connection pool. The pool works as expected, but there is a point during the lifetime of my application where a connection is not used for some time (i.e., it stays in the pool as an available connection). There is some configuration that I am not finding to discard unused connections after some time? Or do I have to manually close those connections?

Best regards,
Jorge

Hi, I haven't seen such a configuration in the code.
The connections are stored in the connection_pool and reused - when a connection is acquired from the list with available connections - a health check is performed - the flow includes a validation that ensures the connection is healthy - in case it isn't - it is reconnected, but there is not logic to discard unused connections after predefined period.
