In this blog post we shall discuss how you can analyze slow query logs from Amazon Aurora for MySQL, (referred to as Amazon Aurora in the remaining blog). The tools and techniques explained here apply to the other MySQL compatible services available under Amazon Aurora.

We believe there is a bug in Aurora where it logs really big numbers for query execution and lock times for otherwise really fast queries.

So, the main steps we need are:

1. Enable slow query logging on your Amazon Aurora DB parameter group, apply the change when appropriate.
2. Download the slow log(s) that …
