Subject [jira] [Commented] (CASSANDRA-8110) Make streaming backwards compatible
Date Thu, 16 Oct 2014 17:04:34 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8110?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14173957#comment-14173957
] 

Marcus Eriksson commented on CASSANDRA-8110:
--------------------------------------------

We version the stream protocol separately, meaning we can have the same streaming protocol
across different major versions. This ticket should make it possible to stream between different
stream message versions whenever we add new stuff there (the thing that broke it between 2.1
and 3.0 was adding the SSTable level in the FileMessageHeader, CASSANDRA-7460 ).

> To be able to seamlessly upgrade clusters we need to make it possible to stream files
between nodes with different StreamMessage.CURRENT_VERSION
