The number of shards that the stream will use. The throughput of the stream is a function of the number of shards; more shards are required
            for greater provisioned throughput. Note: The default limit for an AWS account is 10 shards per stream. If you need to create a
            stream with more than 10 shards, contact AWS Support to
            increase the limit on your account.
