> 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}
