redis HGETALL command Video explanation

redis HGETALL command syntax

Function: Return all fields and values in the hash table key. In the return value, immediately following each field name is the value of the field, so the length of the return value is twice the size of the hash table.

Syntax: HGETALL key

Available versions: >= 2.0.0

Time complexity: O(N), N is the size of the hash table.

Return: Return the domain and domain value of the hash table in list form. If key does not exist, an empty list is returned.
