// The transaction with the given request token is already in progress.
// Recommended Settings This is a general recommendation for handling the
// TransactionInProgressException . These settings help ensure that the client
// retries will trigger completion of the ongoing TransactWriteItems request.
//   - Set clientExecutionTimeout to a value that allows at least one retry to be
//     processed after 5 seconds have elapsed since the first attempt for the
//     TransactWriteItems operation.
//   - Set socketTimeout to a value a little lower than the requestTimeout setting.
//   - requestTimeout should be set based on the time taken for the individual
//     retries of a single HTTP request for your use case, but setting it to 1 second
//     or higher should work well to reduce chances of retries and
//     TransactionInProgressException errors.
//   - Use exponential backoff when retrying and tune backoff if needed.
//
// Assuming default retry policy (https://github.com/aws/aws-sdk-java/blob/fd409dee8ae23fb8953e0bb4dbde65536a7e0514/aws-java-sdk-core/src/main/java/com/amazonaws/retry/PredefinedRetryPolicies.java#L97)
// , example timeout settings based on the guidelines above are as follows: Example
// timeline:
//   - 0-1000 first attempt
//   - 1000-1500 first sleep/delay (default retry policy uses 500 ms as base delay
//     for 4xx errors)
//   - 1500-2500 second attempt
//   - 2500-3500 second sleep/delay (500 * 2, exponential backoff)
//   - 3500-4500 third attempt
//   - 4500-6500 third sleep/delay (500 * 2^2)
//   - 6500-7500 fourth attempt (this can trigger inline recovery since 5 seconds
//     have elapsed since the first attempt reached TC)
