ThrottlingException

The request rate is too high and exceeds the service's throughput limits.

This exception occurs when you send too many requests in a short period of time. Implement exponential backoff in your retry strategy to handle this exception. Reducing your request frequency or distributing requests more evenly can help avoid throughput exceptions.

This exception can also occur when more than two processes are reading from the same stream shard at the same time. Ensure that only one process reads from a stream shard at the same time.
