Sylvain Lebresne updated CASSANDRA-11943:
-----------------------------------------
Fix Version/s: 4.x
> Allow value > 64K for clustering columns
> ----------------------------------------
>
> Key: CASSANDRA-11943
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11943
> Project: Cassandra
> Issue Type: Bug
> Components: Local Write-Read Paths
> Reporter: Lerh Chuan Low
> Assignee: Sylvain Lebresne
> Fix For: 4.x
>
>
> Setup:
> I set this up with a 2 node cluster, but I think with a 1 node cluster it
> would encounter the same issue. Use Cassandra 3.
> {code}
> CREATE KEYSPACE Blues WITH REPLICATION = { 'class' : 'SimpleStrategy',
> 'replication_factor' : 2};
> CREATE TABLE test (a text, b text, PRIMARY KEY ((a), b))
> {code}
> Do the following insert:
> {code}
> CONSISTENCY ALL;
> "INSERT INTO %s (a, b) VALUES ('foo', ?)", '<something that is bigger than
> 64k>')
> {code}
> Everything is fine and you can still run queries and so on, C* looks normal.
> But if we restart C*, it never succeeds in starting up:
> {code}
