Blake Eggleston commented on CASSANDRA-13257:
---------------------------------------------
bq. Is it possible to add "dry-run" feature to stremaing instead of
TreeDifference?
That’s a really good idea. It will also be more accurate than TreeDifference,
since it will measure actual sstable sizes, not the size of the partitions that
come out of the validation compaction.

> It would be useful to be able to estimate the amount of repair streaming that
> needs to be done, without actually doing any streaming. Our main motivation
> for this having something this is validating CASSANDRA-9143 in production,
> but I’d imagine it could also be a useful tool in troubleshooting.
