Subject [jira] [Commented] (CASSANDRA-3648) Repair should validate checksums before streaming
Date Mon, 19 Dec 2011 18:19:30 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3648?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13172464#comment-13172464
] 

Jonathan Ellis commented on CASSANDRA-3648:
-------------------------------------------

However, I'm unsure how useful this is without also validating during read repair.  Presumably
we do this during the normal read path for block checksums, but full file hashes are too heavyweight
for that.

> We have block checksums and sha1 full-file hashes, but currently we do not validate these
before streaming in a repair.
