#[repr(C)]
pub enum DataBlockIndexType {
    BinarySearch = 0,
    BinaryAndHash = 1,
}
Expand description

Used by BlockBasedOptions::set_data_block_index_type.

Variants§

§

BinarySearch = 0

Use binary search when performing point lookup for keys in data blocks. This is the default.

§

BinaryAndHash = 1

Appends a compact hash table to the end of the data block for efficient indexing. Backwards compatible with databases created without this feature. Once turned on, existing data will be gradually converted to the hash index format.
