At Percona we provide services both Onsite - visiting the customers and Remote - logging in to their systems or communicating via email,phone,instant messaging.

We believe both approaches have their benefits and drawbacks and mixing them right way allows you to get your problems solved most efficient way.

Onsite visits are great as they allow consultant to meet your team in person and great for relationship building. It is great for architecture design and review as you can sit down with the team and use drawing board. It also often allows the best focus both for consultant and for participating team - when consulting visit is arranged it is usually the top priority for some of the staff members which provide consultant with information and assistance he might need.

Onsite visits also often allow to get prompt attention from other team - looking for …

I’ve had a few VCs ask how we compare to Hadoop and companies using MapReduce. With Google blessing MapReduce, it seems to be the cool new thing. I figure I’m going to have to explain this to VCs, so I might as well blog about it.

MapReduce is a process of dividing a problem into small pieces and distributing (mapping) those pieces to a large number of computers. Then it collects the processed data and merges (reduces) it into a result set. Hadoop provides the plumbing, so users focus on writing the query and Hadoop handles the dirty work of mapping and reducing. Such a query, using a procedural language like Java, is more complex than a comparable SQL query, but more on that below.

So what is MapReduce good for? It really shines when you want to summarize, analyze or transform a very large data set. This is why it is well suited to web data. Map reduce doesn’t utilize an index, so the tradeoff you need to consider is whether …

Earlier this year I had published a small blog about being efficient when using mysql prompt. This is a small continuation of it highlighting a couple of other cool features which I really find very useful when working command line (i.e. always!). The first I’m gonna list here is setting the prompt itself by typing –

Version 0.4 of libdrizzle has been released. This was mostly a maintenance release with build system changes and small bug fixes. This is the client and protocol library for Drizzle and MySQL that provides both client and server interfaces.

Version 0.4.1 of the Drizzle PHP Extension has also been released. James Luedke has moved development and releases of the extension into PECL, and has also fixed a number of bugs, extended the interface, and worked with the PHP/PECL developers to get the extension up to the proper PHP coding standards. Thanks James!
