I have a redis set. This set can store 20 members maximum(added withSADD
command).
My problem is ; I need to update that members when needed. Members need that modification maximum 10 times for every member. Set members are json as a string. There is only solutoin on my mind nor, get all members update and recreate that set again. But it seems iditoic.
I know there is ZADD
sorted set with its score support it seems suitable also I need to update score like data in json , but i just wonder Is there any method updating members in efficient way, or is updating member not acceptable on redis way ?
