-- 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
-- </streams/latest/dev/building-enhanced-consumers-api.html 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@.
