Orc O'Malley of the Yellow Elephant clan says LLAP

Owen O’Malley on the Origins of Hadoop, Spark and a Vulcan ORC

Owen O’Malley is one of the folks I chatted with at the last Hadoop Summit in San Jose. I already discovered the first time I met him that he was the big Tolkien geek behind the naming of ORC files, as well as making sure that Not All Hadoop Users Drop ACID. In this conversation, I learned that Hadoop and Spark are both partially his fault, about the amazing performance strides Hive with ORC, Tez and LLAP have made, and that he’s a Trek geek, too.

If you asked most people if water could cut through steel, they would probably tell you it can’t. They would be wrong, too.

In-Memory Analytic Databases are So Last Century

In an article written last year by an industry analyst that I respect, IDC’s Carl Olofson, he gave the impression that in-memory analytics are the wave of the future, the new paradigm for high performance analytic databases. He said, “embrace the new paradigm and plan for it.”

For once, I didn’t agree with him.

In-memory analytics are last decade’s revolution, or even last century’s. The wave of the future is something far faster, and far more revolutionary.

Not All Hadoop Users Drop ACID

In the age of businesses with data that lives on dozens or even hundreds of servers, expecting transactional integrity and data consistency and currency are old-fashioned notions. On Hadoop, you just have to settle for the new NoSQL standard of BASE and eventual consistency. That’s what they say. But, as usual, “they” are wrong. Not all Hadoop users have to drop ACID…
