PASS Keynote Day 3

By Wesley Brown, 2011/10/14

Wow,

It’s the last day of the 2011 PASS Summit. I can’t wait to get some sleep on the plane tomorrow.

Wayne Snyder, hero

Wayne has been a huge mover and shaker inside and outside the PASS community. His impact on the community is immeasurable.

Buck and Rob sing!

Here’s hoping their performance makes it to youtube! Just a great way to kick off an early Friday.

THE DEWITT

David Dewitt talks big data. eBay managing 10 petabytes on 256 nodes on a parallel database system. Facebook on the other hand, uses a NoSQL system. Housing 20 petabytes on 2700 notes. Relational isn’t going away and it does scale.

NoSQL

Doesn’t mean No to SQL it is meant to mean Not Only SQL. David is really breaking down the NoSQL, and taking a couple of swings at the developers too.  Hes tone has changed a bit from last year about NoSQL, which is fine he is a smart guy.

Two Major Types of NoSQL

Key/Value Stores MongoDB, CouchBase Cassandra tipically have a flexable model and usually partitions, or shards, on a hash. NoSQL OLTP

Hadoop/Mapreduce

NoSQL Data warehouse

Scaleable, fault tolerant framework. Really meant for storing MASSIVE amounts of data. Really used for analytics and question answering.

Paradigm shift?

NoSQL isn’t a paradigm shift! Relational isn’t going away. NoSQL is another way to get to your data and use it.

I’m not gonna blog everything David talked about, it is a simple overview of Hadoop, so it is crazy detailed and way to much info to put up on my little blog post about today. Go watch the keynote online. Then go watch it again. Finally, watch it again then start asking questions.

Great keynote yet again! I’ll be in the SQL Clinic most of the day so come talk to me about your storage issues and share your stories with me.
