## Properties

- `backoffRate`: number — Backoff between attempts.

  **Default:** 1 (no backoff)

  This is the multiplier by which the retry interval increases
  after each retry attempt.

  By default there is no backoff. Each retry will wait the amount of time
  specified by `interval`.

- `interval`: [Duration](/cdk/api/v2/docs/aws-cdk-lib.Duration.html) = Duration.seconds(5) — The interval (number of seconds) to wait between attempts.

- `providerLogLevel`: [ApplicationLogLevel](/cdk/api/v2/docs/aws-cdk-lib.aws_lambda.ApplicationLogLevel.html) = ApplicationLogLevel.FATAL — The log level of the provider lambda function.

- `totalTimeout`: [Duration](/cdk/api/v2/docs/aws-cdk-lib.Duration.html) = Duration.minutes(30) — The total time that the state machine will wait for a successful response.
