Instrument repair to be able to assess it's efficiency (precision)
------------------------------------------------------------------
Key: CASSANDRA-2698
URL: https://issues.apache.org/jira/browse/CASSANDRA-2698
Project: Cassandra
Issue Type: Improvement
Reporter: Sylvain Lebresne
Assignee: Sylvain Lebresne
Priority: Minor
Some reports indicate that repair sometime transfer huge amounts of data. One
hypothesis is that the merkle tree precision may deteriorate too much at some
data size. To check this hypothesis, it would be reasonably to gather statistic
during the merkle tree building of how many rows each merkle tree range account
for (and the size that this represent). It is probably an interesting statistic
to have anyway.
