15e8b43961 rewrote getWorkersForTLogs to do a much better job of avoiding degraded processes and processes in the same DC as the cluster controller 2021-04-07 19:57:24 -07:00
Evan Tschannen
c27d82cecd tlog recruitment used a degraded LogClass process over a non-degraded TransactionClass process 
tlog recruitment would not use TransactionClass processes if it fulfulled the required amount with LogClass processes
Better master exists did not account for how many times a process had been used when comparing recruitments
Better master exists did not account for the fact that tlogs prefer to be in a different dc than the cluster controller
RoleFitness comparison did not properly order count before degraded or bestFit
betterCount was returning worstFit when worstIsDegraded did not match
backupWorker recruitment did not attempt to avoid sharing processes with other roles
If any of the commit_proxy, grv_proxy, or resolver are forced to share a process, allow the recruitment for all of them to share to an equal degree, this change allows BetterMasterExists to be refactors as a tuple comparison
