Int search_bin sstable st int key

Cassandra is able to binary-search for a given key up to a granularity of 128 keys blocks and then, unfortunately, needs to linearly scan the SSTable from that offset on until it finds the key it's looking for. Reference: p124: Index Files An index file stores the offset of keys into the main data file, which is the SSTable.
