Parameters for ZINCRBY commands <br/> <br/> In fact, Redis doesn't have parameters for ZINCRBY. Instead Redis has INCR parameter for ZADD.<br/> When users call ZADD with INCR option, its restriction (only one member) and return type is same to ZINCRBY. <br/> Document page for ZADD also describes INCR option to act like ZINCRBY. <br/> http://redis.io/commands/zadd <br/> <br/> So we decided to wrap "ZADD with INCR option" to ZINCRBY. <br/> https://github.com/xetorthio/redis/issues/1067 <br/> <br/> Works with Redis 3.0.2 and onwards.
