Web14. okt 2024 · Redis Lists are simply lists of strings sorted by insertion order. This makes them an ideal tool to implement message queues, for instance: jedis.lpush ( "queue#tasks", "firstTask" ); jedis.lpush ( "queue#tasks", "secondTask" ); String task = jedis.rpop ( "queue#tasks" ); Copy The variable task will hold the value firstTask. Redis Data types includes sorted set and other necessary data-structures for key-value storage. But I wonder why it doesn't have any sorted map like Java's TreeMap or C++'s std::map. I think the underlying data-structure would be mostly similar of sorted set as both are supposed to be balanced binary search tree.
