Clarifying SAND’s customer metrics, positioning and technical story

Talking with my clients at SAND can be confusing. That said:

A few months ago, I wrote:

SAND Technology reported >600 total customers, including >100 direct.

Upon talking with the company, I need to revise that figure downward, from > 600 to 15.

Exasol update

I last wrote about Exasol in 2008. After talking with the team Friday, I’m fixing that now. :) The general theme was as you’d expect: Since last we talked, Exasol has added some new management, put some effort into sales and marketing, got some customers, kept enhancing the product and so on.

Top-level points included:

MarkLogic’s Hadoop connector

It’s time to circle back to a subject I skipped when I otherwise wrote about MarkLogic 5: MarkLogic’s new Hadoop connector.

Most of what’s confusing about the MarkLogic Hadoop Connector lies in two pairs of options it presents you:

Otherwise, the whole thing is just what you would think:

MarkLogic said that it wrote this Hadoop connector itself.

Aster Database Release 5 and Teradata Aster appliance

It was obviously just a matter of time before there would be an Aster appliance from Teradata and some tuned bidirectional Teradata-Aster connectivity. These have now been announced. I didn’t notice anything particularly surprising in the details of either. About the biggest excitement is that Aster is traditionally a Red Hat shop, but for the purposes of appliance delivery has now embraced SUSE Linux.

Along with the announcements comes updated positioning such as:

Virtual data marts in Sybase IQ

I made a few remarks about Sybase IQ 15.3 when it became generally available in July. Now that I’ve had a current briefing, I’ll make a few more.

The key enhancement in Sybase IQ 15.3 is distributed query — what others might call parallel query — aka PlexQ. A Sybase IQ query can now be distributed among many nodes, all talking to the same SAN (Storage-Area Network). Any Sybase IQ node can take the responsibility of being the “leader” for that particular query.

In itself, this isn’t that impressive; all the same things could have been said about pre-Exadata Oracle.* But PlexQ goes somewhat further than just removing a bottleneck from Sybase IQ. Notably, Sybase has rolled out a virtual data mart capability. Highlights of the Sybase IQ virtual data mart story include:   Read more

I wanted to learn more about Hadoop and its futures, so I talked Friday with Arun Murthy of Hortonworks.* Most of what we talked about was:

Arun previously addressed these issues and more in a June slide deck.

Eight kinds of analytic database (Part 1)

Analytic data management technology has blossomed, leading to many questions along the lines of “So which products should I use for which category of problem?” The old EDW/data mart dichotomy is hopelessly outdated for that purpose, and adding a third category for “big data” is little help.

Let’s try eight categories instead. While no categorization is ever perfect, these each have at least some degree of technical homogeneity. Figuring out which types of analytic database you have or need — and in most cases you’ll need several — is a great early step in your analytic technology planning.  Read more
