Introduction

This database is designed for high load situations and has a main architecture of Redis and PostgreSQL. Due to the need to generate a large number of personal lists at once, the personal list in PostgreSQL is designed using the List data structure. We first check if the head of the ID -> ListKey exists in Redis. If there is such a list, we update the ID -> ListKey in Redis. When a user visits our database, we output ten pieces of data to them in a lazy tag-like manner, which ensures the throughput performance of the database under heavy traffic.
