Benedict Elliott Smith commented on CASSANDRA-17698:
----------------------------------------------------
(Copied from email reply)
{quote}for old version‘s index data using this version’s dump code ，I think
there
will not be much difference（may be only exception message‘s difference），It
is backwards compactibility I think .But I change the content of
sstable（adding a new base type for partitionordertype）.😅{quote}
Could you explain why this needs to change what is written? It's not clear to
me, nor from skimming the patch. If this does change what is written it _must_
bump the sstable version, but I'd like to understand what's changing and why,
so we can figure out if this needs to be a minor or major bump.
