[jira] [Commented] (CASSANDRA-8110) Make streaming backwards compatible

["Aleksey Yeschenko (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-8110?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14171103#comment-14171103 ] 

Aleksey Yeschenko commented on CASSANDRA-8110:
----------------------------------------------

One direction is easy - and that's older nodes streaming *to* newer nodes, because newer nodes can handle previous-version sstables. That alone would be a significant improvement, and I suggest we start with that first.

The other direction is trickier, because new-format sstables would have to be converted to old-format sstables before streaming, or on the fly.

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