I committed the patch to be released in 2.0.1, with nit style fix and type change(int to long in CountingDigest.count). We can change the log output in the future if needed. > 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: Benedict > Priority: Minor > Labels: lhf > Fix For: 2.0.1 > > Attachments: nodetool_repair_and_cfhistogram.tar.gz, > patch_2698_v1.txt, patch.diff, patch-rebased.diff, patch.taketwo.alpha.diff, > patch.taketwo.forreview.diff, trunk-2698.txt > > > 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. -- This message is automatically generated by JIRA.
