- SpringBoot+Redis Bloom filter prevents malicious traffic from penetrating the cache
- The details are as follows: What is malicious traffic penetration? Assume that our Redis contains a set of user's registered emails, with email as the key, and it corresponds to some fields of the User table in the DB. Generally speaking, when a reasonable request comes in, we will first determine whether the user is a member in Redis, because reading data from the cache returns quickly. If this member does not exist in the cache, then we will query it in the DB. Now imagine that there are tens of millions of requests from different IPs (don’t think there are none, we encountered them in 2018 and 2019, because the cost of attack is very low) to access your website with a key that does not exist in Redis. Let's imagine this: the request arrives at the web server
