MongoDB + Fractal Tree Indexes = High Compression
+2 Vote Up -0Vote Down

One doesn’t have to look far to see that there is strong interest in MongoDB compression. MongoDB has an open ticket from 2009 titled “Option to Store Data Compressed” with Fix Version/s planned but not scheduled. The ticket has a lot of comments, mostly from MongoDB users explaining their use-cases for the feature. For example, Khalid Salomão notes that “Compression would be very good to …

NoSQL is Great, But You Still Need Indexes
+1 Vote Up -0Vote Down

I’ve said it before, and, as is the nature of these things, I’ll almost certainly say it again: your database performance is only as good as your indexes.

That’s the grand thesis, so what does that mean? In any DB system — SQL, NoSQL, NewSQL, PostSQL, … — data gets ingested and organized. And the system answers queries. The pain point for most users is around the speed to answer queries. And the query speed (both latency and throughput, to be exact) depend on how the data is organized. In short: Good Indexes, Fast Queries; Poor …

“With MySQL 5.6, developers can now commingle the “best of both worlds” with fast key-value look up operations and complex SQL queries to meet user and application specific requirements” –Tomas Ulin. On February 5, 2013, Oracle announced the general availability of MySQL 5.6. I have interviewed Tomas Ulin, Vice President for the MySQL Engineering team [...]

Neither fish nor fowl: the rise of multi-model databases
+0 Vote Up -0Vote Down

One of the most complicated aspects of putting together our database landscape map was dealing with the growing number of (particularly NoSQL) databases that refuse to be pigeon-holed in any of the primary databases categories.

I have begun to refer to these as “multi-model databases” in recognition of the fact that they are able to take on the characteristics of multiple databases. In truth though there are probably two different groups of products that could be considered “multi-model”:

True …

NoSQL with MySQL's Memcached API
Employee +0 Vote Up -0Vote Down

One of our training courses has a section covering MySQL's Memcached API, and how it works. In the discussion, there's a line that goes like this:

 "A key is similar to a primary key in a table, and a value is similar to a second column in the same table"

For someone well versed in database tables but not so much in key-value stores, that sentence might take a bit of grasping. So, let's break it down.

An Example Key/Value Store 

Imagine the table kvstore has a column key and a column value. Also imagine that we've set up the Memcached plugin in MySQL and configured it to use that table and those columns …

Introducing Data Fabric Design for Commodity SQL Databases
+2 Vote Up -0Vote Down

Data management is undergoing a revolution.  Many businesses now depend on data sets that vastly exceed the capacity of DBMS servers.  Applications operate 24x7 in complex cloud environments using small and relatively unreliable VMs.  Managers need to act on new information from those systems in real-time. Users want constant and speedy access to their data in locations across the planet.

It is tempting to think popular SQL databases like MySQL and PostgreSQL have no place in this new world.  They manage small quantities of data, lack scalability features like parallel query, and have weak availability models. …

FOSDEM 2013

The Free and Open source Software Developers’ European Meeting (FOSDEM) is a two-day event organized by volunteers to promote the widespread use of Free and Open Source software.

I attended for the first time over the weekend and was really impressed by the number of people there, the energy and the quality of the content. The event really lives up to it’s name and is very developer-focused.

In the end, I got the opportunity to make 2 presentations. The first is a general introduction to MySQL Cluster….

Impressions of FOSDEM 13
+0 Vote Up -0Vote Down

FOSDEM 13 is now over, I am on my way home and I would like to share some thoughts sparkled by the intense atmosphere that I have lived in these two days in Brussels. I have to admit, I was tempted to skip FOSDEM this year: the last 3 weeks have been crazily busy and I travelled a lot, leaving my family alone for too long. But now I am glad I made the effort.
