Yuki Morishita commented on CASSANDRA-6261:
-------------------------------------------
CASSANDRA-2698 added # of rows and sizes to each Merkle tree leaf.
Right now those are only logged in summary to system.log with DEBUG enabled.
And If you want the precise number of rows streamed, we can count as we write
the rows in receiver side.
> Repair should display number of rows that mismatched.

> URL: https://issues.apache.org/jira/browse/CASSANDRA-6261
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: sankalp kohli
> Assignee: Yuki Morishita
> Priority: Minor
>
> Repair currently displays number of ranges which are out of sync. It would be
> helpful to display how many rows that did not match.
> We can do this by sending number of rows with each hash in the Merkle tree.
> Also we can put the size of rows which contributed to that hash.
> So each leaf node in the tree will have a hash and also the number of rows
> and its size.
> We can also emit the avg rows per hash range and also the min and max.
> All this will help in tuning the repair
