Stefan Richter commented on FLINK-6333:
---------------------------------------

Right now, the biggest problem in updating RockDB above version 4.11.2 are bugs 
in rocksjni that will cause some functionality that is used in Flink (e.g. 
merge operator) to segfault. We can only move to a higher version once those 
problems are fixed in RocksDB.

> Utilize Bloomfilters in RocksDb

> Bloom Filters would speed up RocksDb lookups.
> When we upgrade to RocksDb 5.2.1+, we would be able to do:
> {code}
>               new BlockBasedTableConfig()
>                   .setBlockCacheSize(blockCacheSize)
>                   .setBlockSize(blockSize)
>                   .setFilter(new BloomFilter())
> {code}
