Major Changes

Fix VTOrc Discovery

In patch releases prior to release 14.0.3, if VTOrc is unable to reach the MySQL instance of a vttablet, it was never able to read discover that tablet again. This problem could be resolved by restarting the VTOrc so that it discovers all the tablets again, but in a kubernetes cluster where the pods are eviced frequently, this posed a greater challenge, since some pods when evicted and rescheduled on a different node, would sometimes fail to be discovered by VTOrc. This has problem has been addressed in this patch by the fix https://github.com/vitessio/vitess/pull/10662.
