Chris Riccomini commented on SAMZA-543:
---------------------------------------
Oddly, CompactionStyle.LEVEL seemed to be about 2x as fast as UNIVERSAL
(Samza's default), as well. I only looked at write performance, though.

> Project: Samza
> Issue Type: Bug
> Components: kv
> Affects Versions: 0.9.0
> Reporter: Chris Riccomini
> Fix For: 0.9.0
>
>
> RocksDB uses a write-ahead log by default. This is unnecessary in Samza,
> since we have full durability from a state store's changelog topic. We should
> [disable the
> WAL|https://github.com/facebook/rocksdb/wiki/Basic-Operations#asynchronous-writes]
> in the RocksDB KV store.
