Subject [jira] [Created] (CASSANDRA-8261) Clean up schema metadata classes
Date Wed, 05 Nov 2014 19:49:33 GMT
Aleksey Yeschenko created CASSANDRA-8261:
--------------------------------------------

             Summary: Clean up schema metadata classes
                 Key: CASSANDRA-8261
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8261
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Aleksey Yeschenko
            Assignee: Aleksey Yeschenko
            Priority: Minor
             Fix For: 3.0


While working on CASSANDRA-6717, I've made some general cleanup changes to schema metadata
classes - distracted from the core purpose. Also, being distracted from it by other things,
every time I come back to it gives me a bit of a rebase hell.

Thus I'm isolating those changes into a separate issue here, hoping to commit them one by
one, before I go back and finalize CASSANDRA-6717.

The changes include:
- moving all the toThrift/fromThrift conversion code to ThriftConversion, where it belongs
- moving the complied system CFMetaData objects away from CFMetaData (to SystemKeyspace and
TracesKeyspace)
- isolating legacy toSchema/fromSchema code into a separate class (LegacySchemaTables - former
DefsTables)
- refactoring CFMetaData/KSMetaData fields to match CQL CREATE TABLE syntax, and encapsulating
more things in CompactionOptions/CompressionOptions/ReplicationOptions classes
- moving the definition classes to the new 'schema' package
