More on NoSQL and HVSP (or OLRP)

Since posting last Wednesday morning that I’m looking into NoSQL and HVSP, I’ve had a lot of conversations, including with (among others):

Workday comments on its database architecture

In my discussion of Workday’s technology, I gave an estimate that Workday’s database, if relationally designed, would require “1000s” of tables. That estimate came from Workday, Inc. CTO Stan Swete, in a thoughtful email that made several points about Workday’s database strategy. Workday kindly gave me permission to quote it below.

The Workday architecture — a new kind of OLTP software stack

One of my coolest company visits in some time was to SaaS (Software as a Service) vendor Workday, Inc., earlier this month. Reasons included:

Workday kindly allowed me to post this Workday slide deck. Otherwise, I’ve split out a quick Workday, Inc. company overview into a separate post.

The biggie for me was the data and object management part. Specifically:  Read more

I’m collecting data points on NoSQL and HVSP adoption

I was asked to do a magazine article on NoSQL, where by “NoSQL” is meant “whatever they talk about at NoSQL conferences.” By now the number of publications planning to run the article is up to 2, the deadline is next week and, crucially, it has been agreed that I may talk about HVSP in general, NoSQL and SQL alike.

It also is understood that, realistically, I can’t be expected to know and mention the very latest news for all the many products in the categories. Even so, I think this would be fine time to check just where NoSQL and HVSP adoption stand. Here is most of what I know, or links to same; it would be great if you guys would contribute additional data in the comment thread.

In the NoSQL area:  Read more

I’m back from a trip to the SF Bay area, with a lot of writing ahead of me. I’ll dive in with some quick comments here, then write at greater length about some of these points when I can. From my trip:  Read more

Nested data structures keep coming up, especially for log files

Nested data structures have come up several times now, almost always in the context of log files.

I don’t have a grasp yet on what exactly is happening here, but it’s something.

dbShards — a lot like an MPP OLTP DBMS based on MySQL or PostgreSQL

I talked yesterday w/ Cory Isaacson, who runs CodeFutures, makers of dbShards. dbShards is a software layer that turns an ordinary DBMS (currently MySQL or PostgreSQL) into an MPP shared-nothing ACID-compliant OLTP DBMS. Technical highlights included:  Read more

Sybase SQL Anywhere

After Powersoft acquired Watcom and its famed Fortran compiler, marketing VP Tom Herring told me that the hidden jewel of the acquisition might well be a little DBMS, Watcom SQL. To put it mildly, Tom was right. Watcom SQL became SQL Anywhere; Powersoft was acquired by Sybase; Powersoft’s and Sybase’s main products both fell on hard times; Sybase built a whole mobile technology division around SQL Anywhere; and the whole thing just got sold for billions of dollars to SAP. Chris Kleisath recently briefed me on SQL Anywhere Version 12 (released to manufacturing this month), which seemed like a fine opportunity to catch up on prior developments as well.

The first two things to understand about SQL Anywhere is that there actually are three products:

and also that there are three main deployment/use cases:

Riptano, and Cassandra adoption

Tonight’s Cassandra technology post got plenty long enough on its own, so I’m separating out business and adoption issues here. For starters, known Cassandra users include:

Fetlife, Meebo, and others seem to at least have a healthy interest in Cassandra, based on their level of involvement in a forthcoming Cassandra Summit. That said, the @Fetlife tweetstream features numerous yelps of pain, and I don’t mean the recreational kind.  Read more
