Caleb Rackliffe updated CASSANDRA-18490:
----------------------------------------
Description:
The SAI code currently does not checksum validate per-column index data files
at any point. It does checksum validate per-sstable components after a full
rebuild and it checksum validates the per-column metadata on opening.
We should checksum validate all index components on startup, full rebuild and
streaming.
EDIT: The changes we ultimately made here were:
- Fix checksum calculation in {{IncrementalChecksumSequentialWriter}}
- Checksum per-SSTable and per-column components after streaming
- Avoid validating indexes when full rebuild is requested
