Chris Riccomini commented on SAMZA-236:
---------------------------------------
bq. 2. We should implement RocksDB kv and see how it performs. If it solves all
our problems, we can remove support for leveldb.
I'm leaning this way as well.

> Key: SAMZA-236
> URL: https://issues.apache.org/jira/browse/SAMZA-236
> Project: Samza
> Issue Type: Bug
> Components: kv
> Affects Versions: 0.6.0
> Reporter: Chris Riccomini
> Fix For: 0.8.0
>
>
> 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.
