One question which comes up very often is when one should use SAN with MySQL, which is especially popular among people got used to Oracle or other Enterprise database systems which are quite commonly deployed on SAN. My question in such case is always what exactly are you trying to get by using SAN ?
I read very nice post by Matt today and it has many good insights though I can’t say I agree on all points. First there is a lot of people out where which put it as disk is everything. Remember Paul Tuckfield saying “You should ask how many disks they have instead of how many […]
ScaleArc hired Percona to benchmark failover times for the ScaleArc database traffic management software in different scenarios. We tested failover times for various clustered setups, where ScaleArc itself was the load balancer for the cluster. These tests complement other performance tests on the ScaleArc software – sysbench testing for latency and testing for WordPress acceleration. […]

Mk-query-digest tries to handle dropped or missing packets […]
Sometimes the question is put like are you looking for Performance OR Stability, which I believe is a strange way to put it. In real life systems you care both about Performance AND Stability. I would even say Stability is a not the best world here, I would day you care about your minimal performance […]
I’ve presented at two different venues about HandlerSocket recently and the number one question that always arises is: Why hasn’t HandlerSocket become more popular than it is? Considering how fast and awesome HandlerSocket is, it’s not seeing as rapid adoption as some might expect. I theorize that there are five reasons for this:
Many of the prominent companies in the MySQL ecosystem are Percona customers, including hardware manufacturers, software developers, hosted service providers, and appliance developers. We perform paid and unpaid research on their products, and we publish blog posts related to their products or services. Independence and objectivity are core Percona values. How do we balance the […]
As part of our growth process and with the introduction of our Support and Maintenance services, we’re looking for a new Support Engineer.
You would be a part of a unit that operates 24×7 and be the first line of contact for our customers.
Responsibilities include handling or dispatching emergencies and support requests, triaging incoming issues, and ensuring customers always get the attention they need.

I actually was not aware about any real […]
