Subject [jira] [Commented] (CASSANDRA-6261) Repair should display number of rows that mismatched.
Date Mon, 28 Oct 2013 22:12:42 GMT

Brandon Williams commented on CASSANDRA-6261:
---------------------------------------------

Hmm, I suppose it is, though that's a bit more involved.  How hard is it to simply log how
many rows were streamed?

> 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
