Open source’s role in lowering the barriers to data warehousing

As well as contributing to the CAOS research practice here at The 451 Group I am also part of the information management team, with a focus on databases, data caching, CEP, and - from the start of this year - data warehousing.

I’ve covered data warehousing before but taking a fresh look at this space in recent months it’s been fascinating to see the variety of technologies and strategies that vendors are applying to the data warehousing problem. It’s also been interesting to compare the role that open source has played in the data warehousing market, compared to the database market.

I’m preparing a major report on the data warehousing sector, for publication in the next couple of months. What follows is a rough outline of the role open source has played in the sector. Any comments or corrections much appreciated:

Unlike other …

Are closed-source MySQL storage engines compatible with MariaDB?

Following the launch of the Open Database Alliance some people have assumed that it is only a matter of time before MariaDB becomes the de facto replacement for MySQL.

That assumes that Oracle will allow the development of MySQL to stagnate, either deliberately or through neglect - something that we have expressed our doubts about, but even if that were the case it appears that the GPL (or more to the point MySQL’s dual licensing strategy) may restrict the potential for MariaDB.

Curt Monash recently raised the question of whether closed-source storage engines can be used with MySQL (and, by …

Where’s the Calpont source code?

As you may have noticed, Calpont has been advertising themselves as an open-source storage engine for MySQL. And yet there is no source code.

A bit of back-story. When we were choosing speakers for the Percona Performance Conference, I personally reviewed Calpont’s submission and sent them an email on March 19th:

I cannot confirm that this is an open-source columnar storage engine. I can’t find source code or a download of the software. Can you point me the right direction on that? I want to be sure we are describing things accurately.

The response was

Calpont is indeed going to be placed into …

Oracle to acquire Sun
Unless you’ve been living under a rock (or like me you decided to take a few inappropriately-timed days off) you probably noticed that Oracle announced an agreement to acquire Sun this week. Jay delivered our assessment on Oracle’s open source credentials, while I followed up with some …

The potential impact of Sun-Oracle on MySQL, and its partners

“We’re both in the transportation business. We have a 747, and they have a Toyota.”

The comparison of Oracle’s database and MySQL, made by Oracle president Charles Phillips at the 2004 Vortex Conference was undoubtedly meant as a criticism, but it so graphically demonstrated the differing business strategies and selling-points of the two products that MySQL executives began citing it themselves.

It is also a comparison that explains how the two products could potentially co-exist within a single company, as they seem likely to do following the announcement that Sun has agreed to be acquired by Oracle.

Much of the MySQL-related coverage of the impending acquisition has focused on the likelihood of Oracle killing-off the …
