Create a consumer named <consumername>
in the consumer group <groupname>
of the stream that's stored at <key>
.
Consumers are also created automatically whenever an operation, such as XREADGROUP
, references a consumer that doesn't exist.
This is valid for XREADGROUP
only when there is data in the stream.
