Part 8 – 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 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
