Struct rexrocksdb::rocksdb_options::BlockBasedOptions

pub struct BlockBasedOptions { /* fields omitted */ }

Methods

impl BlockBasedOptions

pub fn new() -> BlockBasedOptions

pub fn set_block_size(&mut self, size: usize)

pub fn set_lru_cache(
    &mut self,
    size: size_t,
    shard_bits: c_int,
    capacity_limit: c_uchar,
    pri_ratio: c_double
)

the recommanded shard_bits is 6, also you can set a larger value as long as it is smaller than 20, also you can set shard_bits to -1, RocksDB will choose a value for you the recommanded capacity_limit is 0(false) if your memory is sufficient the recommanded pri_ratio should be 0.05 or 0.1

pub fn set_bloom_filter(&mut self, bits_per_key: c_int, block_based: bool)
