Background

The feedback interval for queued sessions (i.e. sessions waiting to become active) was specified as a constant 30s. This could potentially lead to some clients closing their Exasol connections if this interval was too long and the connection was regarded as inactive.

Improvement

The feedback interval for queued sessions is now specified to use the same feedback interval which is used for active sessions. The interval is configurable via parameter feedbackinterval / FEEDBACKINTERVAL (please refer to pages under Drivers dedicated to particular drivers).
