Configuration for Archive storage.

Fields

translator: T

Logic to transform keys into their index representation.

Archive assumes that all internal keys are spread uniformly across the key space. If that is not the case, lookups may be O(n) instead of O(1).

metadata_partition: String

The partition to use for per-section validation markers. Recovery adopts entries below a section’s marker without re-validating their values.

key_partition: String

The partition to use for the key journal (stores index+key metadata).

key_page_cache: CacheRef

The page cache to use for the key journal.

value_partition: String

The partition to use for the value blob (stores values).

compression: Option<u8>

The compression level to use for the value blob.

codec_config: C

The commonware_codec::Codec configuration to use for the value stored in the archive.

items_per_section: NonZeroU64

The number of items per section (the granularity of pruning).

Fixed for the life of the archive’s data. Records live in the section their index selects, and Archive::init fails with crate::archive::Error::RecordCorrupted when a stored record’s section no longer matches. Each retained section tracks its indices in a vector spanning every offset up to its highest stored index (8 bytes each), so sparse indices in a large section cost up to 8 * items_per_section bytes (see Indexing).

key_write_buffer: NonZeroUsize

The amount of bytes that can be buffered for the key journal before being written to a commonware_runtime::Blob.

value_write_buffer: NonZeroUsize

The amount of bytes that can be buffered for the value journal before being written to a commonware_runtime::Blob.

replay_buffer: NonZeroUsize

The buffer size to use when replaying a commonware_runtime::Blob.

Trait Implementations

impl<T: Clone + Translator, C: Clone> Clone for Config<T, C>
