Sam Tunnicliffe commented on CASSANDRA-6801: -------------------------------------------- I was able to reproduce this on a single node using the schema detailed above (but with SimpleStategy). Flush is also unnecessary, the problem manifests without it. The additional commit added for CASSANDRA-6623 (5ef53e6f7) fixes this. > INSERT with IF NOT EXISTS fails when row is an expired ttl > ---------------------------------------------------------- > > Key: CASSANDRA-6801 > URL: https://issues.apache.org/jira/browse/CASSANDRA-6801 > Project: Cassandra > Issue Type: Bug > Components: Core > Reporter: Adam Hattrell > > I ran this on a 2 DC cluster with 3 nodes each. > CREATE KEYSPACE test WITH replication = { > 'class': 'NetworkTopologyStrategy', > 'DC1': '3', > 'DC2': '3' > }; > CREATE TABLE clusterlock ( > name text, > hostname text, > lockid text, > PRIMARY KEY (name) > ) ; > Then add some data and flush it to ensure the sstables exist (didn't > reproduce in memtables for some reason). > Then > insert into clusterlock (name, lockid, hostname) values ( 'adam', 'tt', > '111') IF NOT EXISTS USING TTL 5; > Wait for ttl to be reached then try again: > insert into clusterlock (name, lockid, hostname) values ( 'adam', 'tt', > '111') IF NOT EXISTS USING TTL 5; > > [applied] > ----------- > False > select * shows no rows in table. -- This message was sent by Atlassian JIRA (v6.2#6252)
