How Hadooped is SQL Server PDW with Polybase?

Now for SQL Server… continuing the thread on RDBMS-Hadoop integration (Part 1, Part 2, Part 3, Part 4, Part 5, Part 6, Part 7) I have suggested that we could evaluate integration architecture using three criteria: How parallel are the pipes to move data between the RDBMS and the parallel file system; Is there intelligence to push down predicates; and Is…

Part 6: How Hadooped is HANA?

Now for HANA plus Hadoop… to continue this thread on RDBMS-Hadoop integration (Part 1, Part 2, Part 3, Part 4, Part 5) I have suggested that we could evaluate integration architecture using three criteria: How parallel are the pipes to move data between the RDBMS and the parallel file system; Is there intelligence to push…

Part 1: How Hadooped is Your RDBMS?

Sorry for the comic adjective “Hadooped”? The next few blogs will try to evaluate the different approaches to integrating Hadoop and a standard RDBMS… so the first thing I’ll try in this post is to suggest a criteria based on some architectural  choices for making the evaluation. Further, I’ll inject a little surprise and make…

HANA, BLU, Hekaton, and Oracle 12c vs. Teradata and Greenplum – November 2013

I would like to point out a very important section in the paper on Hekaton on the Microsoft Research site here. I will quote the section in total: 2. DESIGN CONSIDERATIONS  An analysis done early on in the project drove home the fact that a 10-100X throughput improvement cannot be achieved by optimizing existing SQL…

BLU Meanies: Data In-memory

IBM is presenting a DB2 Tech Talk that compares the BLU Accelerator to HANA. There are several mistakes and some odd thinking in the pitch so let me address the issues as a way to explain some things about HANA and about BLU. This blog will consider what data needs to be in-memory. IBM like…

Oracle 12c IMDB Announcement at OOW13

I changed the picture to show you the billboard SAP bought on US101N right across from the O HQ… – Rob Larry Ellison announced a new in-memory capability for Oracle 12c last night. There is little solid information available but taken at face value the new feature is significant… very cool… and fairly capable. In…

The Hype of Big Data

As preface to this you might check out the definition I suggested for Big Data last week here… – Rob I left Greenplum in large part because they made their mark in… and then abandoned… the  data warehouse market for a series of big hype plays: first analytics and data science; then analytics, data science,…

The Big Data Devil

I just finished a draft for next week on Big Data and thought that with this note I might form a preface… First… Big Data is about, well…, Big Data. When Gartner devised the three V’s I suspect that they were trying to frame the new stuff that was emerging… not establish a concise definition.…
