MySQL Performance: Pushing yet more far scalability limits with MySQL 5.7
Employee +2 Vote Up -0Vote Down

MySQL 5.7-RC1 is available now since the last week and you may find a lot about all the new improvement coming from our Team Blog and many other blog posts on this site as well. While in this article I'll just mention that with MySQL 5.7 all scalability limits are going more and more far! -- it's not that we resolved all of them, no, just that we become better and better ;-)

Ever Wondered How Pythian is Kind of Like a Fire Truck?
+0 Vote Up -0Vote Down

 

I have.

Coming from the world of selling fire trucks I’m used to selling necessary solutions to customers in need. The stakes are high. If the truck doesn’t perform best case scenario it’s a false alarm. Worst case scenario someone, many people, die.

Let me tell you a bit about fire trucks.

A lot of people think that a fire truck is a fire truck. That there is some factory where fire trucks are made, carbon copies of one another, varying only in …

Sometimes trying to keep a post short and to the point raises other questions. Clearly, my Python-MySQL Program post over the weekend did raise a question. They were extending the query example and encountered this error:

TypeError: range() integer end argument expected, got tuple.

Practical P_S: Which TLS ciphers are connections using?
Employee +0 Vote Up -0Vote Down

As noted in an earlier post, MySQL Server 5.7 prefers and enables SSL/TLS connections by default.  That’s great and useful progress towards secure connections, but we know that not all SSL/TLS ciphers are created equal – some are older and more vulnerable.  Furthermore, some recent vulnerabilities rely on the ability to negotiate less-secure ciphers during the handshake.  Monitoring which ciphers are used can help identify connections using low-grade ciphers, but also to build an appropriate …

How to win at IO-bound benchmarks
+0 Vote Up -0Vote Down

I spend time evaluating database performance on IO-bound workloads and have learned a few things that can help you to get much better results on benchmarks than will occur in production. But this is really about benchmarketing.

The tips are:

  • Load the database in key order to avoid a fragmented B-Tree index or a randomized LSM tree. If there is a secondary index then create it after the load to avoid fragmentation there. This makes the database smaller and can make searches faster.
  • Only use 10% of the storage device. …
