> Could we add a checksum to the Summary file and filter file of the SSTable. 
> Since reads the whole bloom filter before actually reading data, it seems like it would make sense to checksum the bloom filter to make sure there is no corruption there. Same is true with the summary file. The core of our question is, can you add checksumming to all elements of the SSTable so if we read anything corrupt we immediately see a failure?
