Struct rocksdb::BlockBasedOptions

pub struct BlockBasedOptions { /* fields omitted */ }

For configuring block-based file storage.

Methods

impl BlockBasedOptions

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

pub fn set_lru_cache(&mut self, size: size_t)

pub fn disable_cache(&mut self)

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

pub fn set_cache_index_and_filter_blocks(&mut self, v: bool)

pub fn set_index_type(&mut self, index_type: BlockBasedIndexType)

Defines the index type to be used for SS-table lookups.

Example

use rocksdb::{BlockBasedOptions, BlockBasedIndexType, Options};

let mut opts = Options::default();
let mut block_opts = BlockBasedOptions::default();
block_opts.set_index_type(BlockBasedIndexType::HashSearch);

pub fn set_pin_l0_filter_and_index_blocks_in_cache(&mut self, v: bool)

If cache_index_and_filter_blocks is true and the below is true, then filter and index blocks are stored in the cache, but a reference is held in the "table reader" object so the blocks are pinned and only evicted from cache when the table reader is freed.

Default: false.
