Rafael Sanches created CASSANDRA-11222:
------------------------------------------

             Summary: datanucleus-cassandra won't work with cassandra 3.0 system.* metadata.
                 Key: CASSANDRA-11222
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11222
             Project: Cassandra
          Issue Type: Wish
          Components: CQL
         Environment: Java JDO
            Reporter: Rafael Sanches
            Priority: Blocker
             Fix For: 3.0.x


Hi, 

I'm starting a new project and was hoping to upgrade directly to cassandra 3.0, so it would
save us a migration from 2.2 later on. 

Unfortunately, the datanucleus-cassandra-5.0.0-m1 (latest) don't support the 3.0 data model.


Errors like these will appear because of JDO:
https://issues.apache.org/jira/browse/CASSANDRA-10996

To be more specific, this class does things like:
StringBuilder stmtBuilder = new StringBuilder("SELECT keyspace_name FROM system.schema_keyspaces
WHERE keyspace_name=?;");

https://github.com/datanucleus/datanucleus-cassandra/blob/master/src/main/java/org/datanucleus/store/cassandra/CassandraSchemaHandler.java

It doesn't seem like the Datanucleus guys are looking to fix this, since the last update on
datanucleus-cassandra was on 2014. I will open an issue there too. Hope can reach contributors
from both places. 

I guess opening an issue here is more a "heads up", because more developers will waste time
on this soon.

thanks
rafa
