--------------------------------------------------
Summary: Accord: Various fixes and improvements
Key: CASSANDRA-20361
URL: https://issues.apache.org/jira/browse/CASSANDRA-20361
Project: Apache Cassandra
Issue Type: Bug
Components: Accord
Reporter: Benedict Elliott Smith
Fix:
- Only use persisted RedundantBefore for compaction
- RouteIndex should index only touches, not Route
- Flush RangesForEpoch updates to journal immediately, so we do not rely on
the command we are processing succeeding
- DurableBefore updates must wait for the epochs to be known locally
- Shard.mustWitnessEpoch to support guaranteeing to witness relevant
non-topology schema changes
- We must propagate RedundantBefore RX shard bounds along with epoch syncs
- Prevent a truncated transaction FetchData infinite loop
- GC_BEFORE status being overwritten by bootstrappedAt, permitting old
transaction state to be resurrected
- Avoid CFK.maxUniqueHlc read race on bootstrap
- TopologyManager.awaitEpoch could wait for wrong epoch
Also improve:
- CommandStores uses SearchableRangeList for finding matching stores
- Refactor RedundantBefore to use a sorted array of TxnId/RedundantStatus
pairs (to better fix GC_BEFORE issue)
- Accord debug keyspace operates on keyspace/table, and sorts correctly by
token
