Tuning In terms of tuning, two parameters can be tuned, the size of the bitmap and the number of bits set by every value. For good performance, the filter blocks are cached in the RocksDB block cache and normally stay there since they are accessed frequently. In most cases a bitmap of a few hundred bytes is sufficient.
