Where ParAccel is at
Sounds as if ParAccel can do more than I thought until now: it’s a columnar DB, can run in-memory, can manage and take advantage of dual copies on DAS and SAN. I already got that they’re performance-obsessed 🙂

What’s Essential – And What’s Not – In Big Data Analytics
Very good article about What’s Essential – And What’s Not – In Big Data Analytics. Starts with a Big Data Analytics overview, then dives into the columnar vs. row based DBs debate (only to find that that’s ultimately not generally important, as all these systems are built to scale, and it depends on your data…

How to Improve the Resilience of your MPP Sharding

Addressing Big-Data Challenges
Ramon Chen, of Rainstor, in a long, Q&A-styled article about Addressing Big-Data Challenges. Unfortunately I know this behaviour he mentions just too well: At a more granular level, organizations continue to retain critical, structured, transactional data in production system environments far longer than is legally required.

EMC Greenplum Data Computing Appliance
I’ve been wanting to write about the EMC Greenplum Data Computing Appliance for a while now, but that launch just took longer than expected.

The Oracle Critical Patch Update October 2010 is out, see the Oracle Security Blog for commentary. Of the 9 Database related vulnerabilities, 7 do not apply if you are on the latest patchset on 10gR2 or 11gR2, a much higher than usual number, and hopefully a good sign for what’s to come.

eBay replaces Greenplum with Teradata
A quicky: eBay followup — Greenplum out, Teradata > 10 petabytes, Hadoop has some value, and more. Interesting to see that the impression is that Greenplum got thrown out more for reliability reasons than performance. EBay also was repeatedly mentioned as a key customer using the MapReduce integration piece in the past, there’s also an…
