Syntax: `ZMSCORE KEY MEMBER [MEMBER ...]` This is an extension of #2359 amended by Tyson Andre to work with the changed unstable API, add more tests, and consistently return an array. - It seemed as if it would be more likely to get reviewed after updating the implementation. Currently, multi commands or lua scripting to call zscore multiple times would almost definitely be less efficient than a native ZMSCORE for the following reasons: - Need to fetch the set from the string every time instead of reusing the C pointer. - Using pipelining or multi-commands would result in more bytes sent by the client for the repeated `ZMSCORE KEY` sections. - Need to specially encode the data and decode it from the client for lua-based solutions. - The fastest solution I've seen for large sets(thousands or millions) involves lua and a variadic ZADD, then a ZINTERSECT, then a ZRANGE 0 -1, then UNLINK of a temporary set (or lua). This is still inefficient. Co-authored-by: Tyson Andre <tysonandre775@hotmail.com> |
