--------------------------------------------------
Summary: Accord: Never recover read-only transactions; simply
invalidate
Key: CASSANDRA-19359
URL: https://issues.apache.org/jira/browse/CASSANDRA-19359
Project: Cassandra
Issue Type: Improvement
Components: Accord
Reporter: Benedict Elliott Smith
read-only transactions do not need to be recovered to supply client responses
or for other transactions to make progress. The only situation that might
require a read to be recovered is for recovery of a write transaction that
needs to know whether the read might have witnessed or not-witnessed it at a
specific `executeAt`. This can be special-cased, either to run recovery in this
circumstance, or to simply compute the necessary recovery information to decide
whether it is possible or not.
