Adding Materialized View triggers "Mutation Too Large" error.

2016-08-08 Thread Jason J. W. Williams
HI Guys, We're running Cassandra 3.0.8, and needed to add a field to a table and it's materialized views. We dropped the MVs, added the fields to the underlying table, and recreated MVs with the new fields. However, the MV creation is failing with: WARN [CompactionExecutor:6933] 2016-08-08 22:4

I can vouch for TWCS...we switched from DTCS to TWCS using Jeff's plugin w/ Cassandra 3.0.5 and just upgraded to 3.0.8 today and switched over to the built-in version of TWCS. -J On Mon, Jul 11, 2016 at 1:38 PM, Jeff Jirsa wrote: > DTCS is deprecated in favor of TWCS in new versions, yes. > > >

Adding column to materialized view

2016-06-27 Thread Jason J. W. Williams
Hey Guys, Running Cassandra 3.0.5. Needed to add a column to a materialized view, but ALTER MATERIALIZED VIEW doesn't seem to allow that. So we ended up dropping the view and recreating it. Is that expected or did I miss something in the docs? -J

Multi-DC Cluster w/ non-replicated Keyspace

2016-06-16 Thread Jason J. W. Williams
Hi Guys, We have a 2 DC cluster where the keyspaces are replicated between the 2. Is it possible to add a keyspace to one of the DCs that won't be replicated to the other? Whenever we add a new keyspace it seems to get replicated even if we don't specify the other DC in the keyspace's NetworkTopo

Optional TLS CQL Encryption

Hey Guys, Is there a way to make TLS encryption optional for the CQL listener? We'd like to be able to use for remote management connections but not for same datacenter usage (since the build/up tear down cost is too high for things that don't use pools). Right now it appears if we enable encryp
