RESTORE-ASKING

Syntax
RESTORE-ASKING key ttl serialized-value [REPLACE] [ABSTTL]
  [IDLETIME seconds] [FREQ frequency]
Available since:
3.0.0
Time complexity:
O(1) to create the new key and additional O(N*M) to reconstruct the serialized value, where N is the number of Redis objects composing the value and M their average size. For small string values the time complexity is thus O(1)+O(1*M) where M is small, so simply O(1). However for sorted set values the complexity is O(N*M*log(N)) because inserting values into sorted sets is O(log(N)).
ACL categories:
@keyspace, @write, @slow, @dangerous,

The RESTORE-ASKING command is an internal command. It is used by a Redis cluster master during slot migration.
