github.com/bsm/sntable (go): Package sntable contains a custom SSTable implementation which, instead of arbitrary bytes strings, assumes 8-byte numeric keys.  A store contains a series of data blocks followed by an index and a store footer.  A block comprises of a series of sections, followed by a section index and a single-byte compression type indicator.  A section is a series of key/value pairs where the first key is stored as a full uint64 while subsequent keys are delta encoded.
