Use ZPOPMIN to remove and return the members with the lowest scores in a sorted set. Without a count one member is returned with its score, and with a count up to that many are removed, ordered from the lowest score up. The key is deleted once the last member is popped. With a timestamp or a priority number as the score, this is how a sorted set becomes a scheduler or a priority queue: the next item due is always the minimum, and popping it atomically means only one worker can pick it up. BZPOPMIN is the blocking form.

Syntax

Arguments

Important points

  • RESP2 represents floating-point reply values as bulk strings; RESP3 may use native double replies. Client libraries commonly decode either form to a language number.

Response

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 TLS REDIS_URL from the Upstash console. REST examples use UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN.
