// Registers a consumer with a Kinesis data stream. When you use this operation,
// the consumer you register can then call SubscribeToShard to receive data from
// the stream using enhanced fan-out, at a rate of up to 2 MiB per second for every
// shard you subscribe to. This rate is unaffected by the total number of consumers
// that read from the same stream. You can register up to 20 consumers per stream.
// A given consumer can only be registered with one stream at a time. For an
// example of how to use this operations, see Enhanced Fan-Out Using the Kinesis
// Data Streams API . The use of this operation has a limit of five transactions
// per second per account. Also, only 5 consumers can be created simultaneously. In
// other words, you cannot have more than 5 consumers in a CREATING status at the
// same time. Registering a 6th consumer while there are 5 in a CREATING status
// results in a LimitExceededException .
