Hi all. Is any support matrix for 'pentaho-cassandra-plugin' available?

Just recently spent a half day in debugger and did not success at making cassandra output do output as desired.
I had 5.3 PDI and 5.3 plugin. We use 'apache-cassandra-1.2.18'.

When attempts to use PDI cassandra output step - shows green. I have opened in debugger - it is uses
https://github.com/pentaho/pentaho-c...dler.java#L159
query executed - but nothing really written.

Is it versions inconsistency?
