Value log configuration

Implementations§

Source§

impl<BC: BlobCache, C: Compressor + Clone + Default> Config<BC, C>

Source

pub fn new(blob_cache: BC) -> Self

Creates a new configuration builder.

Source

pub fn compression(self, compressor: Option<C>) -> Self

Sets the compression & decompression scheme.

Source

pub fn blob_cache(self, blob_cache: BC) -> Self

Sets the blob cache.

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

Source

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
