In addition to reporting whether the replica is active or not, measured performance should be reported so as to indicate whether a replica might impact cluster performance or might be in danger of failing. > We're probably not close to doing automated replica fail over, but we can give the administrator some clues. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
