Struct value_log::Config

pub struct Config { /* private fields */ }

Value log configuration

Implementations

impl Config

pub fn use_compression(self, compression: CompressionType) -> Self

Sets the compression type to use.

Using compression is recommended, see CompressionType.

Default = none

pub fn blob_cache(self, blob_cache: Arc<BlobCache>) -> Self

Sets the blob cache.

You can create a global BlobCache and share it between multiple value logs to cap global cache memory usage.

Defaults to a blob cache with 16 MiB of capacity per value log.

pub fn segment_size_bytes(self, bytes: u64) -> Self

Sets the maximum size of value log segments.

This heavily influences space amplification, as space reclamation works on a per-segment basis.

Like blob_file_size in RocksDB.

Default = 256 MiB

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
