BZPOPMIN

Note

Official reference: BZPOPMIN.

Wait and pop the lowest-scoring member from the first nonempty sorted set.

Syntax​

BZPOPMIN key [key ...] timeout

timeout is in seconds. Use a nonnegative integer literal; 0 waits indefinitely.

Results​

ReturnRowsContent
ResultSet1KEY field, STRING type
ELEMENT field, STRING type
SCORE field, DOUBLE type
Caution

When all source sets are empty (or a blocking call times out), the current driver can fail rather than reliably return an empty ResultSet. Use a Redis client when this case must be handled.
