[jira] [Updated] (CASSANDRA-3559) CFMetaData conversions to Thrift/Avro should probably be inverse one of the other

     [ https://issues.apache.org/jira/browse/CASSANDRA-3559?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sylvain Lebresne updated CASSANDRA-3559:
----------------------------------------

    Attachment: 3559.patch

Note that this actually tests CASSANDRA-3558 and hence the uni test won't pass without it.

> In other word, it would probably be a idea to have:
> {noformat}
>   cfm == CFMetadata.fromThrift(cfm.toThrift())
>   cfm == CFMetadata.fromAvro(cfm.toAvro())
> {noformat}
> In particular, we could have unit tests to check that, which would avoid things like CASSANDRA-3558.
> It is not the case today for thrift because of the keyAlias. For some reason, if the keyAlias is not set, we return with toThrift() the default alias. I don't think this serves any purpose though.
> The goal of this ticket is to both fix that (unless there is a compelling reason not to) and add unit tests for this.
