As we close out the holiday season, let’s look at some data that tells us how to guarantee a successful Black Friday (from a database perspective).

There are certain peak times of the year where companies worldwide hold their breath in the hope that their databases do not become overloaded or unresponsive. A large percentage of yearly profits are achieved in a matter of hours during peak events. It is critical that the database environment remains online and responsive. According to a recent survey, users will not wait more than 2.5 seconds for a site to load before navigating elsewhere. Percona has partnered with many clients over the years to ensure success during these critical events. Our goal is always to provide our clients with the most responsive, stable open-source database environments in order to meet their business needs.

I spent all of this week at O’Reilly Velocity EU London. I gave a tutorial, a talk and generally networked with attendees (besides my normal evangelical duties). I’ll write some thoughts on it later (probably in a couple of weeks, as Open Source Summit Europe happens next week – and Percona has a booth there).

This will be a quick, short post.

Percona latest blog poll asks how you currently host applications and databases. Select an option below, or leave a comment to clarify your deployment!

With the increased need for environments that respond more quickly to changing business demands, many enterprises are moving to the cloud and hosted deployments for applications and software in order to offload development and maintenance overhead to a third party. The database is no exception. Businesses are turning to using database as a service (DBaaS) to handle their data needs.

DBaaS provides some obvious benefits:

• Offload physical infrastructure to another vendor. It is the responsibility of whoever is providing the DBaaS service to maintain the physical environment – including hardware, software and best …

In this post, we will discuss how to fix cardinality for InnoDB tables manually.

As a support engineer, I often see situations when the cardinality of a table is not correct. When InnoDB calculates the cardinality of an index, it does not scan the full table by default. Instead it looks at random pages, as determined by options innodb_stats_sample_pages, innodb_stats_transient_sample_pages and innodb_stats_persistent_sample_pages, or …
