DedupKey

Struct DedupKey 

Source
pub struct DedupKey(/* private fields */);
Expand description

An idempotent-append deduplication key: a 64-byte SHA3-512 digest that is a deterministic function of (namespace, payload).

An ingest pipeline keys in-flight and recently-committed records by their DedupKey; a re-submission (network retry, at-least-once delivery, a client replaying a request) produces the same key and can be dropped before it double-appends. The key is post-quantum (SHA3-512), domain-separated, and namespace-scoped, so keys never collide across namespaces or across the two derivation modes.

Two derivations are offered:

  • DedupKey::from_record keys on the content itself (the canonical leaf bytes). Identical content in the same namespace is the same record.
  • DedupKey::from_token keys on a client-supplied idempotency token (e.g. a request UUID). Use this when the same logical submission may carry non-identical bytes (timestamps, nonces) yet must append at most once.

The key is opaque; compare keys for equality or use DedupKey::as_bytes / DedupKey::to_hex as a storage index.

Implementations§

Source§

impl DedupKey

Source

pub fn from_record(namespace: &Namespace, payload: &[u8]) -> Self

Derive a content-addressed dedup key from a namespace and the canonical record bytes: SHA3-512_ctx("…/content/v1", lp(ns) || lp(payload)).

Source

pub fn from_token(namespace: &Namespace, token: &[u8]) -> Self

Derive a dedup key from a namespace and a client-supplied idempotency token: SHA3-512_ctx("…/token/v1", lp(ns) || lp(token)).

Source

pub fn as_bytes(&self) -> &[u8; 64]

The raw 64-byte key.

Source

pub fn to_hex(&self) -> String

The key as lowercase hex (128 chars) — a convenient storage-index form.
