Description
There have been a few reports where SwitchReads fail with a
keyspace partition for MASTER in cell xxxx does not start with min keyerror. This error happens when the SrvKeyspace is inconsistent. This PR adds validations to check that the SrvKeyspace is consistent while creating a workflow and before and after workflow state changes. Hopefully if there is a bug these checks and added logs will help surface it, or it will alert the user in case the SrvVSchema was not consistent before invoking a vrep command.Checklist
