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
