Navina Ramesh commented on SAMZA-543:
-------------------------------------

Yeah. I noticed that difference too. It could be due to the block size that is 
used in the block-based table format. I am yet to investigate in that 
direction.

> 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

>  in the RocksDB KV store.
