There are few terms you need to have a good understanding if you’re working with high volume systems. I commonly see these mixed and people not understanding the difference between them. Performance – The performance comes down to performing up to users expectations (or expectations of your boss) which drills down to two important metrics […]
Percona is hiring. We’ve added several experts recently and we’re growing at a fast but sustainable pace. The demand for our services is strong, and we have openings for more experts in the next couple of months. Let me explain a little about what we’re looking for at the moment. While we do have a […]
…any sessions this year; Peter, Vadim, and the rest of us at Percona submitted over a dozen session proposals, which were initially declined. As …Cabral is organizing.
