The problem/use-case that the feature addresses The current keyspace notifications do not distinguish between creation of a key or updating an existing key. This is especially important in the case of Streams, as the stream is created upon first XADD.
Description of the feature
Add a keyspace notification even of 'key-created' along with the key name
Alternatives you've considered
Existing keyspace notifications can not provide an answer. The workaround, in case of Redis Gears, is to hold some flag if this was the first update, although this is a clunky solution at best.
