Expand description

A trait with methods that get called by the pool on certain events.

Required methods

A connection was checked out

A connection that was previously checked out was checked in again

A newly created connection was checked in

A connection was dropped because it was marked as defect

A new connection was created

The number of idle connections increased by 1

The number of idle connections decreased by 1

The number of in flight connections increased by 1

The number of in flight connections decreased by 1

A reservation has been enqueued

A reservation was fulfilled. A connection was available in time.

A reservation was not fulfilled. A connection was mostly not available in time.

The reservation queue has a limit and that limit was just reached. This means a checkout has instantaneously failed.

The connection factory was asked to create a new connection but it failed to do so.

A pool internal message was received
