Summary: Accord: Improve and Document CoordinateShardDurable
semantics
Key: CASSANDRA-19296
URL: https://issues.apache.org/jira/browse/CASSANDRA-19296
Project: Cassandra
Issue Type: Improvement
Components: Accord
Reporter: Benedict Elliott Smith
Firstly, CoordinateShardDurable should retry in future epochs if necessary. In
principle this isn't a problem; the next CoordinateShardDurable should pick up
where this one left-off. But we should consider the logic very carefully, and
anyway not leave dangling waits.
We should also carefully consider the special-case where replicas are
bootstrapping in the future and we are coordinating the shard durability. This
replica should safely participate in the sync point, waiting for only the
transactions it requires to be replicated to it. So this should also function
as expected, but this should be tested and documented carefully.
