Sometimes I find that we are so stubborn with MySQL that ending up with a complicated design, and I&#39;ve even seen a solution that stores data in MySQL and then using Redis as a cache for it to improve read performance in the meanwhile. And to make the data in the cache as consistent as possible with the data in MySQL, it introduces other mechanisms, but the result is still not 100% consistent.</p>
