StartReplay

Source: src/AWS/EventBridge/StartReplay.ts

Starts a replay of archived events (events:StartReplay).

Bind this operation to an Archive inside a function runtime to get a callable that replays a time window of archived events onto a destination event bus — the runtime half of disaster-recovery and backfill tooling. Provide the StartReplayHttp layer on the Function to satisfy the binding.

Replaying Events

// init — bind the archive (provide AWS.EventBridge.StartReplayHttp on the Function)
const startReplay = yield* AWS.EventBridge.StartReplay(archive);

// runtime — replay yesterday's events back onto the archive's source bus
const replay = yield* startReplay({
  ReplayName: "backfill-2026-07-14",
  EventStartTime: new Date("2026-07-14T00:00:00Z"),
  EventEndTime: new Date("2026-07-15T00:00:00Z"),
});
