 | `rocksdb_filtering_prefix_length` | `12` | Specifies the prefix length for each key. Optional values are `12` and `16`. The configuration is measured in bytes. |
 | `enable_partitioned_index_filter` | - | When set to `true`, it reduces the amount of memory used by the bloom filter. But in some random-seek situations, it may reduce the read performance. |
