In this Checklist for Success series, we will discuss reducing unknowns when hosting in the cloud using and migrating to Amazon Aurora. These tips might also apply to other database as a service (DBaaS) offerings.

In our previous article, we discussed the importance of continuous query performance analysis, especially in Amazon Aurora where there is less diagnostic visibility compared to running on EC2 or on-premise. Aside from uptime though, we need a lot more from our data, and we definitely cannot isolate it in Aurora.

Next on our checklist is that at one point or another, we will need to use asynchronous replication. Amazon Aurora has an excellent reputation for absorbing intense amounts of …

Has you may already know, in MySQL it is possible to set an expiration period for passwords.

It’s not always obvious to see when the password will expire. And most of the time if you don’t pay much attention you will get something like this:

ERROR 1820 (HY000): You must reset your password using
ALTER USER statement before executing this statement.

Let me share you a small query that check for how long your password is still valid in case it was created with an expiration delay or if the global default_password_lifetime is set on …

In this series of blog posts, I’m going to look at some high availability reference architecture solutions over geographically distributed areas.

The Problem

Nowadays, when businesses plan a new service or application, it is very common for them to worry about ensuring a very high level of availability. 

It doesn’t matter if we are talking about an online shop, online banking or the internal services of a large organization. We know users are going to expect access to services 24x7x365. They also expect to access data consistently and instantaneously. If we fail to meet their expectations, then they move to another provider and we lose money. Simple as that.

The other important aspect of providing online …

If you have an application that need to use multiple connections to the MySQL database for short periods of times, it can be a good to use a connection pool to avoid creating a new connection and going through the whole authentication process every time a connection is needed. For the Python Database API (PEP249), MySQL Connector/Python has had support for connection pools for a long time. With the release of MySQL 8.0.13, the new X DevAPI also has support for connection pools.

This blog will first cover the background of the X DevAPI connection pool feature in MySQL Connector/Python. Then …
