Wiaoj.Idempotency.Abstractions

The contract for recording "this has already been handled", so work that arrives twice runs once.

dotnet add package Wiaoj.Idempotency.Abstractions

What is here

  • IdempotencyKey — a validated key string, parsable and formattable (ISpanParsable, IUtf8SpanParsable, ISpanFormattable), with a JSON converter.
  • IIdempotencyStore — the store contract:
Member Meaning
TryMarkProcessedAsync(key, window) Claim the key: true for the first caller, false for every later one inside the window. The operation everything else is built on.
ContainsAsync(key) Has this key been claimed and not expired?
MarkProcessedAsync(key, window) Record the key unconditionally.
RemoveAsync(key) Release a claim, for rolling back after a failure.

The contract knows nothing about HTTP, webhooks or messaging: it is membership with a TTL.

Claim before the work, not after. TryMarkProcessedAsync is a check and a reservation in one step; checking with ContainsAsync and then recording leaves a window where two callers both see "not yet".

Implementations

Package Store Use it when
Wiaoj.Idempotency In-process dictionary One process, and a restart losing claims is acceptable
Wiaoj.Idempotency.Redis Redis SET NX PX More than one replica, or claims must outlive a restart
