---------------------------------------
I test your patch with my [latest pull
request|https://github.com/facebook/rocksdb/pull/318]. It worked on my Mac. On
my RHEL box, I got:

> Issue Type: Bug

>
> The samza-kv implementation is currently using LevelDB. RocksDB seems to have
> a number of interesting options that would be useful to Samza:
> # Ability to swap out skip list for a faster implementation when restoring
> data from a changelog stream.
> # Ability to disable compaction during changelog stream restoration.
> # Ability to have a single level (or single SST) rather than multiple levels
> in order to reduce read amplification.
> # A merge operation for doing lazy read-modify-write during compaction.
> And a lot more.
