This repository contains an extended range of sorted set commands for Redis written in Lua. Commands are registered through the ioredis redis client for node.
Adds a member to a sorted set with the current timestamp as the score for the member.
client.zaddTs(key, member);Same as zadd which is used internally, O(log(N)) for each item added, where N is the number of elements in the sorted set.
Integer reply.
Checks if an entity is a member of a sorted set, added using the zaddTs command. Similar to sismember but only works for members added with the zaddTs command.
client.zismember(key, member);O(1)
Integer if the entity is a valid member, null otherwise. Can be safely cast to boolean.
Removes all the members in a sorted set older than the specified date. Works only with sets having members added using the zaddTs command.
client.zremrangebyscoreTs(key, timestamp);Same as zremrangebyscore which is used internally, O(log(N)+M) with N being the number of elements in the sorted set and M the number of elements removed by the operation.
Integer reply, the number of members removed.
