Query results not ordered despite WITH CLUSTERING ORDER BY

Question

I am storing posts from all users in table. I want to retrieve post from all users the user is following.

CREATE TABLE posts (
  userid int,
  time timestamp         


        

Answer 1

This is my new schema,

CREATE TABLE posts(id uuid, 
userid int,
follows int,
created timestamp,
PRIMARY KEY (userid, follows)) WITH CLUSTERING ORDER BY (created DESC);

Here userid represents who posted it and follows represents userid for his one of the follower. Say user x follows 10 other people , i am making 10+1 inserts. Definitely there is too much data duplication. However now its easier to get timeline for one of the user with following query

select * from posts where follows=?
