fdbserver/Ratekeeper.actor.cpp:557:40: runtime error: signed integer overflow: -9223372036854775808 - 9223372036854775807 cannot be represented in type 'long long'
Since Ratekeeper and DataDistributor are no longer running with Master, they
might be running with stateful processes before a new Master becomes alive,
which is undesirable.
This PR adds a monitoring of both Ratekeeper and DataDistributor at Cluster
Controller -- if Master runs on a stateless class and RK/DD runs at a worse
class, then RK/DD will be killed. I.e., RK/DD should be running at their own
classes or on the same stateless process as Master. After restart, RK/DD should
be running at a better process class.
Add a flag in HealthMetrics to indicate that batch priority is rate limited.
Data distributor pulls this flag from proxy to know roughly when rate limiting
happens.
DD uses this information to determine when to do the rebalance in the background,
i.e., moving data from heavily loaded servers to lighter ones. If the cluster is
currently rate limited for batch commits, then the rebalance will use longer
time intervals, otherwise use shorter intervals. See BgDDMountainChopper() and
BgDDValleyFiller() in DataDistributionQueue.actor.cpp.
