Yuki Morishita commented on CASSANDRA-13257:
--------------------------------------------
bq. validate that repaired data is in sync
I'm not sure this should go to {{nodetool repair}} command. If we have
subcommand, then {{nodetool repair validate}} would be the right command.
Does this need to "preview" streaming as well? Seems validating repaired
SSTables is enough.
About {{PreviewKind}} in streaming, it is how SSTables are selected and I'm
fine with it for now until we have more cleaner way to decouple from streaming
itself.
bq. We’d only ever be able to preview the full repair case.
Would it be so? I will look up CASSANDRA-13328 as well.

> 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.
