RANDOMKEY to get the name of a random key from the database without reading its value.
The reply is null when the database is empty. Keys are picked by sampling the keyspace rather than by drawing uniformly from it, and nothing prevents the same key from coming up repeatedly, so treat it as a way to look at a sample of your data while debugging rather than as a way to iterate over it. Use SCAN when you need to cover every key.
Syntax
Arguments

The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.
Examples
TCP examples use the TLSREDIS_URL from the Upstash console. REST examples use UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN.
