1 is stored separately. Each comment is sent to cid, which is a hash commentinfo: $ cid {cid: $ cid, time: XXX. author: xxx ......}. Each article has a set commentlist: $ aid [cid1, cid2, cid3.].

2. Each article has an sort set conmentlist: $ aid. score is the timestamp, and value is a complete json data string.

Which storage method is better?
