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.
> Repair should validate checksums before streaming
