Jonathan Ellis commented on CASSANDRA-47:
-----------------------------------------
bq. I would prefer putting this index and the header into a separate component
(a -Compression component ?) ... it would also avoid to have to wait that we
close the file to write those metadata
+1
bq. a version number at the beginning
Are we really going to version compression separately from the "main" sstable
version? Seems like it will be rare enough that we only need the latter.
bq. the compression algorithm, the chunk size
+1, that's good futureproofing.
bq. we also really need to have compression an option
+1
> SSTable compression
