DescribeReplay

Source: src/AWS/EventBridge/DescribeReplay.ts

Reads the progress and state of an event replay (events:DescribeReplay).

Bind this operation inside a function runtime to poll a replay started with StartReplay until it completes. Provide the DescribeReplayHttp layer on the Function to satisfy the binding.

Replaying Events

// init — bind the operation (provide AWS.EventBridge.DescribeReplayHttp on the Function)
const describeReplay = yield* AWS.EventBridge.DescribeReplay();

// runtime — read the replay's state and progress
const replay = yield* describeReplay({ ReplayName: "backfill-2026-07-14" });
console.log(replay.State, replay.EventLastReplayedTime);
