Struct Config

pub struct Config<T: Translator> {
    pub registry: Arc<Mutex<Registry>>,
    pub section_mask: u64,
    pub key_len: u32,
    pub translator: T,
    pub pending_writes: usize,

    pub compression: Option<u8>,
}

Configuration for Archive storage.

Fields

registry: Arc<Mutex<Registry>>

Registry for metrics.

section_mask: u64

Mask to apply to indices to determine section.

This value is index & section_mask.

key_len: u32

Length of each key in bytes.

Archive assumes that all keys are of the same length. This trick is used to store data more efficiently on disk and to substantially reduce the number of IO during initialization. If a key is provided that is not of the correct length, an error will be returned.

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).

pending_writes: usize

The number of writes to buffer in a section before forcing a sync in the journal.

If set to 0, the journal will be synced each time a new item is stored.

replay_concurrency: usize

The number of blobs to replay concurrently on initialization.

compression: Option<u8>

Optional compression level (using zstd) to apply to data before storing.

Trait Implementations

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

fn clone(&self) -> Config<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
