If you need to do bulk importing into InnoDB Cluster, it is certainly possible to do so by using any of:

• mysqldump logical dump
• tab separated dump, exported with SELECT..INTO OUTFILE statement or by using mysqldump with --tab option. And import with LOAD DATA..INFILE

Unfortunately both imports will add load to instances and to channels interconnecting instances: data imported on the primary instance needs to be replicated to the rest of instances. And the bigger the data to import, the higher the load (and this could end up affecting performance). The import operation could be batched to reduce load, and Group …

As people are getting back from vacations and application traffic is going back and hitting database backend hard, it is a good time to think about performance and prepare for the winter holiday spike. Whenever you are on-premise or in the cloud, questions are the same:

• Are we satisfied with the current MySQL performance?
• How much traffic are we currently serving?
• Is there enough capacity to stay stable as traffic increases?
• What would be the best way to stay cost-effective as we grow?

Unfortunately, the answers are not so obvious and require a thorough performance analysis. However, there is a chance that your problem has already been solved by someone else. I do not mean StackOverflow (which is a beautiful place, by the way), but some higher level questions which people usually discuss at conferences, and we have several of them ongoing or just a couple of weeks away.

Dear Dave,

My DBA told me that an account I use to talk to my MySQL database instance has TWO passwords! How does that happen? Do I have to provide both passwords every time? 

Sincerely,

A Confused User Who Does Not Want to Type Two Passwords All The Time


Dear Confused User,

Dual Password Support was added in MySQL 8.0.14 and it is a very handy thing. User accounts can now have a primary password and a secondary password. Image a scenario where you are rotating passwords as directed by your company policy but it takes a while to change the credentials in all your code despite your best EMACS magic. The ability to keep the servers up and active as your do your security due diligence is very helpful.

This presentation is a summary of the MySQL 8.0.17 new features.

A constant in the computing world is that it is always evolving and offering new challenges and opportunities. Software solutions come and go with some becoming staples in the business community while others barely cause a ripple as they disappear into the ether. Take MySQL as an example. From its humble beginnings in 1994, the platform has grown to become the most popular SQL database in 2019. If you are a database professional, chances are very good that you work with MySQL regularly.

The popularity of the database platform has not gone unnoticed by the unscrupulous entities that engage in cybersecurity attacks with nefarious intentions. Whether acting …
