Should I worry about the Query Cache in Aurora ?

There are a lot of blog posts on the internet which warn you about using the Query Cache in MySQL.

I was surprised to see that the query cache was enabled in Aurora.

This was the size on a ‘db.r3.large’ instance.

On a ‘db.r3.2xlarge’  instance, it was set to 2460900352 i.e. 2.4GB

I am not sure, if amazon has done something to improve the query cache.

So, do run tests with Aurora and see if the cache suits you.
