------------------------------------------
Summary: Paxos repair interrupts running transactions
Key: CASSANDRA-20469
URL: https://issues.apache.org/jira/browse/CASSANDRA-20469
Project: Apache Cassandra
Issue Type: Bug
Components: Feature/Lightweight Transactions
Reporter: Ariel Weisberg
Assignee: Ariel Weisberg
Noticed that with PaxosV1 there may be transactions being interrupted by auto
repair on clusters with very low transaction rates and no contention.
`PaxosCleanupLocalCoordinator` could wait when it encounters a ballot with a
timestamp that is recent until the transaction timeout has elapsed. This would
make it impossible to interrupt a transaction that is currently running at
client unless it is also trying to recover an existing transaction which is
generally not as common.
