One quick note, sort of a “to whom it may concern,” is that the proper trademarked names of our products include “Percona Server”, “Percona XtraDB”, […]

Modeling InnoDB Scalability on Multi-Core Servers

Mat Keep’s blog post on InnoDB-vs-MyISAM benchmarks that Oracle recently published prompted me to do some mathematical modeling of InnoDB’s scalability as the number of cores in the server increases. Vadim runs lots of benchmarks that measure what happens under increasing concurrency while holding the hardware constant, but not as many with varying numbers of […]

At Percona, we consider it important not only to have the best peak performance, but also stable and predictable performance. I refer you […]

Percona Server with XtraDB Case Study, Behind the Scenes

We’ve published our first case study. The customer, ideeli, had a database that was struggling on standard MySQL and InnoDB. The big win was the upgrade to XtraDB. The business continued to grow quickly, and months later under much more traffic, the database is still outperforming their previous version. I thought I’d write a few […]

Dear Community, Today we are pleased to announce the release 10 of Percona Server with XtraDB storage engine. Since the previous release 9.1 there are following changes

Impossible – possible, moving InnoDB tables between servers

This is probably the feature I missed most from early days when I started to use InnoDB instead of MyISAM. Since that I figured out how to survive without it, but this is first question I hear from customers who migrated from MyISAM to InnoDB – can I just copy .ibd files from one server […]
