We announced a while back that we were going to continue the traditional MySQL conference in Santa Clara, because O’Reilly wasn’t doing it anymore. But we haven’t given an update in a while. Here’s the current status: We created a conference committee. We created a conference website that allows people to create an account and […]
We have a great line up of Tutorials on Percona Live, London. I hand picked number of them after seeing outstanding speaker Performance in other Places. Let me tell in little bit more details about people we have invited and their talks. Yoshinori Matsunobu Talk on Linux Hardware and Optimizations for MySQL at Oreilly MySQL […]
In my previous posts I highlighted that one of improvements in Percona Server is support of innodb_log_file_size > 4G. This test was done using Percona Server 5.5.7, but the same performance expected for InnoDB-plugin and MySQL 5.5.
I recently mentioned a few of the big “non-starter” limitations Postgres has overcome for specific use cases. I decided to write a series of blog posts on MySQL’s unsolved severe limitations. I mean limitations that really hobble it for major, important needs — not in areas where it isn’t used, but in areas where it […]
A couple of weeks ago one of my colleagues and I worked on a data corruption case that reminded me that sometimes people make unsafe assumptions without knowing it. This one involved SAN snapshotting that was unsafe. In a nutshell, the client used SAN block-level replication to maintain a standby/failover MySQL system, and there was […]
We recently released XtraDB-9, and while we did not highlight it in announcement, the release-making feature is ability to save and restore InnoDB buffer pool. The idea is not new and was originally developed by Jeremy Cole (sorry, I do not have the link on hands) some time ago, and now we implemented it in […]
In the last 2 blog posts about High Availability for MySQL we have introduced definitions and provided a list of ( questions that you need to ask yourself before choosing a HA solution. In this new post, we will cover what is the most popular HA solution for MySQL, replication.
After having reviewed the definition my the previous post (The definitions), the next step is to respond to some questions. Do you need MySQL High-Availability? That question is quite obvious but some times, it is skipped. It can also be formulated “What is the downtime cost of the service?”. In the cost, you need to […]
As my first contribution to the MySQL Performance Blog, I joined Percona at the beginning September, I chose to cover the various high-availability (HA) options available for MySQL.Â I have done dozen of MySQL HA related engagements while working for Sun/MySQL over the last couple of years using Heartbeat, DRBD and NDB cluster and I’ll […]
