HMGET key field [field ...]

Available since 2.0.0.

Time complexity: O(N) where N is the number of fields being requested.

Returns the values associated with the specified fields in the hash stored at key.

For every field that does not exist in the hash, a nil value is returned. Because non-existing keys are treated as empty hashes, running HMGET against a non-existing key will return a list of nil values.

*Return value

Array reply: list of values associated with the given fields, in the same order as they are requested.
