-----------------------------------
Summary: Cleanup Cell equality
Key: CASSANDRA-8947
URL: https://issues.apache.org/jira/browse/CASSANDRA-8947
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Benedict
Assignee: Benedict
Priority: Minor
Fix For: 2.1.4
As pointed out by [~dbrosius], it is possible for AbstractCell to generate
false positive equality assertions if, e.g., a non-expiring cell is replaced by
an expiring equivalent. It's not clear to me if this would ever be a real
problem, since we would reconcile correctly, and as such equality would
unlikely ever be a problem (it's used rarely, only really for hash maps I think
(although auditing this is difficult) in which the hash code would also be
different, and by which point we should have resolved conflicts). It's also a
very small exposure profile, with either non-ttl'd writes mixed with ttl'd, or
a delete of a value representing the deletion timestamp.
