'How to switch from hmset() to hset() in Redis?
I get the deprication warning, that Redis.hmset() is deprecated. Use Redis.hset() instead.
However hset() takes a third parameter and I can't figure out what name is supposed to be.
info = {'users': 10, "timestamp": datetime.utcnow().strftime('%Y-%m-%d %H:%M:%S')}
r.hmset("myKey", info)
The above works, but this requires a first parameter called name.
r.hset(name, "myKey", info)
Solution 1:[1]
hmset(name, mapping): given a hash name ("myKey") and a dictionary (info) set all key/value pairs.
hset(name, key=None, value=None, mapping=None): given a hash name ("myKey") a key and a value, set the key/value. Alternatively, given a dictionary (mapping=info) set all key/value pairs in mapping.

If this does not work, perhaps you need to update the library?
Solution 2:[2]
The problem is that you must specify within hset() that you are giving it the mapping. In your case:
r.hset("myKey", mapping=info)
instead of
r.hset("myKey", info)
Solution 3:[3]
I was using Redis.hmset() as following:
redis.hmset('myKey', info)
If you use Redis.hset() the following you will not get warning.
redis.hset('myKey', key=None, value=None, mapping=info)
With this usage, we will skip the single key & value adding step and redis.hset() will set all of the key and value mappings in info to myKey.
