CASSANDRA-20389 implemented limit on table name length of 222
characters. This commit updates the documentation to reflect this.
It also adds an assert in CreateTableValidationTest to ensure that the
documented limit matches the actual constant.
patch by Ruslan Fomkin; reviewed by Brad Schoening, Dmitry Konstantinov for CASSANDRA-20914
Merge ConfigurationService with TopologyManager to remove cyclic dependency and duplicated work.
Also:
- Improve visibility of work blocking topology processing
- Ensure we cannot double-count peers when deciding an epoch's distributed readiness
- Remove the possibility of distributed stalls, by processing new topologies as soon as a
contiguous sequence is known locally, regardless of whether anyprior local epoch is ready to
coordinate or has recorded this fact to peers. The notification of local readiness continues
to be processed only once all prior epochs are ready, but we can begin using and readying
later epochs immediately.

Also fix:
- Paxos should not update minHlc if AccordService is not setup
- Remove EndpointMapper methods that require non-null, to ensure call-sites handle null case explicitly
- AccordRepair should specify the Node Ids that must participate, but these should not affect the durability requirements for GC
- Avoid erroneously marking UniversalOrInvalidated when only known to quorum
- AccordSyncPropagator should not consult FailureDetector as it may throw UnknownEndpointException
- Refuse ReplaceSameAddress if accord enabled
- Reset Accord topologies on restart if no local command stores to ensure we can catch up (as intervening epochs may have otherwise been GC'd)
- MaybeRecover should not abort if found durable if either: 1) prevProgressToken already witnessed durable; or 2) Home state has requested we recover anyway
- Invariant in MaybeRecover is too strong now we permit recovering when known to be stable
- ReadData must respond with InsufficientAndWaiting if not Stable to ensure Durability is inferred correctly by ExecuteTxn
- Avoid StackOverflowException in NotifyWaitingOn
- PreAccept should honour the REJECTED flag of any member of the latest topology if the vote would be relied upon for any prior epoch's quorum
- Resume Accord bootstrap on restart
- Fix burn test non-determinism
- Reset Accord topologies on restart if no local command stores to ensure we can catch up (as intervening epochs may have otherwise been GC'd)
- Exclude stale or removed ids from sync points
- Terminate a failed DurabilityRequest if a required participant is now removed/hardRemoved
Also improve:
- Introduce accord_debug_keyspace.{listeners_txn, listeners_local}
- Filter and record faulty in AbstractCoordination
- If we are the home shard, and our home progress status is done, we should not wait for the home shard to advance the waiting progress state
- Introduce CommandStore.tryExecuteListening to try to execute all waiting transactions and their dependencies
- ExecuteTxn on recovery should not wait, to avoid consuming progress log concurrency slots for transactions that cannot execute
- HomeState should update its phase based on the command status to handle operator request to retry all states
- Separate home/wait queue in DefaultProgressLog
- Additional tracing
- Do not call trySendMore from prerecordFailure
- Force full recovery for sync points if we have lost quorum

- Introduce pattern tracing, that can intercept failed or new coordinations matching various filters
- Support additional tracing event collection modes (SAMPLE and RING)
patch by Benedict; reviewed by Alex Petrov for CASSANDRA-20911
Also Improve:
- Searchable system_accord_debug.txn
- Integrate txn_blocked_by deadline and depth filter with execution logic, to ensure we terminate promptly and get a best effort reply
patch by Benedict; reviewed by Aleksey Yeschenko for CASSANDRA-20899
To support recovering a node that has lost some of its local transaction log, introduce rebootstrap and unsafe bootstrap modes, where Accord ensures no responses are produced for transactions the node cannot be certain it had not previously answered.
