[jira] [Updated] (CASSANDRA-3648) Repair should validate checksums before streaming

     [ https://issues.apache.org/jira/browse/CASSANDRA-3648?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vijay updated CASSANDRA-3648:
-----------------------------

    Attachment: 0001-CASSANDRA-3648.patch

Attached patch has DataIntegratyMetadata for Uncompressed SST's, basically while flushing the buffer checksum is calculated and written to a separate CRC file. while streaming for bootstrap or after manual repair, we will check the chunk checksum (If crc file exists) before streaming the data over. 

Let me know if this is good enough. For RR it is kind of really expensive and we might be better off with compressed Data than checking for checksums.

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