Guozhang Wang updated KAFKA-4850:
---------------------------------

*Reminder to the contributor / reviewer of the PR*: please note that the code deadline for
1.0.0 is less than 2 weeks away (Oct. 4th). Please re-evaluate your JIRA and see if it still
makes sense to be merged into 1.0.0 or it could be pushed out to 1.1.0, or be closed directly
if the JIRA itself is not valid any more, or re-assign yourself as contributor / committer
if you are no longer working on the JIRA.

> Bloom Filters would speed up RocksDb lookups. However they currently do not work in RocksDb
5.0.2. This has been fixed in trunk, but we'll have to wait until that is released and tested.

> Then we can add the line in RocksDbStore.java in openDb:
> tableConfig.setFilter(new BloomFilter(10));
