Sylvain Lebresne commented on CASSANDRA-11882:
----------------------------------------------
bq. From the comments above I understand the fix will need a change in
StatsMetadata format, which could require major version change or would
otherwise be involved enough to warrant a separate ticket.
Hum, somehow missed that comment, sorry. I guess that make sense, but this only
limit each clustering column value to be <= 64k, while the patch currently
limit the total size of all clustering values to be <= 64k. I guess if we don't
forget to create a ticket to fix the sstable metadata (which you can indeed
feel free to assign to me), then I guess I'm fine refusing larger than 64k
values for clustering columns for now, as long as we don't limit the
{{Clustering}} as a whole.

> Key: CASSANDRA-11882
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11882
> Project: Cassandra
> Issue Type: Bug
> Components: CQL, Streaming and Messaging
> Reporter: Lerh Chuan Low
> Fix For: 2.1.x, 2.2.x
>
> Attachments: 11882-2.1.txt, 11882-2.2.txt, 11882-3.X.txt

> Setup:
> {code}
> CREATE KEYSPACE Blues WITH REPLICATION = { 'class' : 'SimpleStrategy',
> 'replication_factor' : 2};
> CREATE TABLE test (a text, b text, PRIMARY KEY ((a), b))
> {code}
> There currently doesn't seem to be an existing check for selecting clustering
> keys that are larger than 64k. So if we proceed to do the following select:
> {code}
> CONSISTENCY ALL;
> SELECT * FROM Blues.test WHERE a = 'foo' AND b = 'something larger than 64k';
> {code}
> An AssertionError is thrown in `ByteBufferUtil` with just a number and an
> error message detailing 'Coordinator node timed out waiting for replica nodes
> responses' . Additionally, because an error extends Throwable (it's not a
> subclass of Exception), it's not caught so the connection between the
> coordinator node and the other nodes which have the replicas seem to be
> 'stuck' until it's restarted. Any other subsequent queries, even if it's just
> SELECT where a = 'foo' and b = 'bar', will always return the Coordinator
> timing out waiting for replica nodes responses'.
