Receive messages from a Kinesis stream.

It's possible to use DynamoDB for persisting shard iterators by setting the
table name. Offsets will then be tracked per ` + "`client_id`" + ` per
` + "`shard_id`" + `. When using this mode you should create a table with
` + "`namespace`" + ` as the primary key and ` + "`shard_id`" + ` as a sort key.`,
	}
