At this time there are three Hadoop appliances in the market:Oracle’s Big Data appliance, Netapp’s Hadooplers and EMC’s Greenplum DCA. It looks like a lot of companies that did not already adopt Hadoop in 2011, are looking to do so in 2012, and some of them may be considering going with an appliance. I want to take a look at some of the reasons a company will be interested in a Hadoop appliance, and what are the differences between the different appliances.

A client running CentOS 5.4 Amazon EC2 instances needed the latest libMemcachedversion installed. With the inclusion of the “make rpm” target, libMemcached makes it easy to build the libMemcached RPMs by doing the following: Spin up a new CentOS Amazon…

With all the buzz in OOW about the big data machine, there was also a lot of non-sense flying around. I love it that the Oracle community is finally interested in Hadoop and NoSQL, but I hate it when people sound authoritative without having an actual clue. I’ve left a few presentations with smoke coming out of my ears. Here are few things that people got all wrong

Oracle announced the Big Data Appliance on Monday morning keynote. Many people, me included, were long waiting for this to happen. Others didn’t think it will ever happen. So naturally, there is a lot of buzz and excitement around the new device in Open World. The keynote announcement was very short on details and certainly did not satisfy my technical curiosity. So I went to a few presentations to hear what exactly is included in the offering. Here’s what I found out.

Oracle Big Data Appliance (BDA) is being announced at the Oracle OpenWorld keynote as I’m posting this. It will take some time for it to be actually available for shipment and some details will likely change but here is what we have so far about Oracle Big Data Appliance.

I’ve attended the Strata conference in NYC last week. Its been many years since I’ve last attended a conference without presenting in it. I decided to attend the conference since it is considered the foremost data science conference. And I was very much interested in what those data scientists are up to. I share some of it here.

We don’t pay enough attention to Hadoop. By “we” I mean DBAs, the rest of the world is paying plenty of attention to Hadoop. Recently, I started asking my customers and fellow DBAs about Hadoop adoption in their company. Turns out that many of them have Hadoop. Hadoop shows up in large companies and small ones, in established industries and in startups. Its everywhere. Let me tell you what it is and why it’s important.

This week’s Log Buffer in its Log Buffer #232 has lumped some interesting posts together.

Well the last busy day here in The Big Apple again a number of very good technical talks. It is not often that the developer of a key piece of a technology gives an intro talk so I grasped it when it came up. Robert Haas gave a very informative talk on the theory behind WAL (Write Ahead Logging) and how it is implemented on PostgreSQL as compared to other DBs. His talk never ventured into the neither world of techno-babel but gave just enough of the technical side to get the understanding out. In the second part of his talk Robert focused on a introduction of the ‘Buzz’ words of WAL that one might have to deal with. There were some other great presentatios as well, I mention a few here

The keynote this year was by Ed Boyajian the CEO or EnerpriseDB and he gave an big picture of the DB in terms of market which is a whopping 26$ Billion a year in the US alone of which the the two five players have 90% of the market one having more than half. If you are intrested in finding out about the rest of the presentation I attended keep reading.
