Igor Zubchenok commented on CASSANDRA-9328: ------------------------------------------- I completely discouraged. Is there any workaround on this? If CAS can not be actually used on non-idempotent operations, what is a real use of current LWT implementation? > WriteTimeoutException thrown when LWT concurrency > 1, despite the query > duration taking MUCH less than cas_contention_timeout_in_ms > ------------------------------------------------------------------------------------------------------------------------------------ > > Key: CASSANDRA-9328 > URL: https://issues.apache.org/jira/browse/CASSANDRA-9328 > Project: Cassandra > Issue Type: Bug > Components: Coordination > Reporter: Aaron Whiteside > Attachments: CassandraLWTTest2.java, CassandraLWTTest.java > > > WriteTimeoutException thrown when LWT concurrency > 1, despite the query > duration taking MUCH less than cas_contention_timeout_in_ms. > Unit test attached, run against a 3 node cluster running 2.1.5. > If you reduce the threadCount to 1, you never see a WriteTimeoutException.
