In this PR, the blob manager now recruits blob workers
(via communication with the cluster controller). Blob workers
are onboarded as blob worker processes enter the cluster.
Changes:
storageserver.actor.cpp: Use counters to capture (a) how fast a storage
server is catching up in versions and (b) the version fetch frequency.
Status.actor.cpp: Report the captured counter metrics as part of storage
metrics.
Changes:
Schemas.cpp: Extend the JSON schema to report whether the cluster is
bounceable and if not, report the reason for why it is not bounceable.
Status.actor.cpp: Extend recoveryStateStatusFetcher() to populate the
bounce related field(s).
mr-status-json-schemas.rst.inc: Update the schema to reflect the change
made in Schemas.cpp.
release-notes-700.rst: Add a note about the new status fields in "Status"
section.
Changes:
Schemas.cpp: Extend the JSON schema to include a new field that reports
the number of seconds since last full recovery.
Status.actor.cpp: Extend recoveryStateStatusFetcher() to populate the
new field that has been added to Schemas.cpp.
mr-status-json-schemas.rst.inc: Update the schema to reflect the change
made in Schemas.cpp.
Changes:
Schemas.cpp:
- Extend JSON schema to include aggregated information about
CommitBatchingWindowSize samples.
Status.actor.cpp:
- Extend getStorageServersAndMetrics() to gather metrics about
CommitBatchingWindowSize.
- Extend CommitProxy AddRole() to populate the status-JSON object
with the metrics about CommitBatchingWindowSize.
We can have LogSets where there are no tLogs but some LogRouters. Its
the way recruiting is implemented for old LogRouters in
TagPartitionedLogSystem, where it adds an empty LogSet for missing
locality.
I ran this command in my build directory after compiling with
OPEN_FOR_IDE. It took a few small tweaks to get it to compile, which is
outside the scope of this commit.

Added transactions.rejected_for_queued_too_long for bookkeeping the
number of transactions rejected by commit proxy because its queuing
time exceeds MVCC window.
