-----------------------------------

             Summary: RocksDb cannot use Bloom Filters
                 Key: KAFKA-4850
                 URL: https://issues.apache.org/jira/browse/KAFKA-4850
             Project: Kafka
          Issue Type: Improvement
          Components: streams
    Affects Versions: 0.10.2.0
            Reporter: Eno Thereska
            Priority: Minor
             Fix For: 0.11.0.0


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));
