I have just read the “Lakehouse: A New Generation of Open Platforms that Unify Data Warehousing and Advanced Analytics” paper and decided to write a short blog post going through some of the key moments of the paper’s motivation. Let’s start.
I’d start with a bold statement: Hadoop is rapidly losing the momentum. We can see it from the following Google Trends chart:
Yesterday my blog has got the 100th subscriber. To commemorate this, I prepared the post on the major industry trends happening in the field of “data”. I might miss something, so feel free to comment and extend the article with your opinion!
Even though Gartner has removed “Big Data” from the last year’s hype diagram, it does not mean it suddenly moved from the peak of the “hype” to the plateau of adoption. Here is how the hype cycle look like:
Hadoop is known to be an ideal engine for processing unstructured data. But wait, what do you really mean by “unstructured data”? Can anything be considered as a “data” if it does not have a structure? Let’s start by taking a look at the historical brief.
Over the latest time I’ve heard many discussions on this topic. Also this is a very popular question asked by the customers with not much experience in the field of “big data”. In fact, I dislike this buzzword for ambiguity, but this is what the customers are usually coming to us with, so I got to use it.
If we take a look 5 years back, that was the time when Hadoop was not an option for most of the companies, especially for the enterprises that ask for stable and mature platforms. At that very moment the choice was very simple: when your analytical database grow beyond 5-7 terabytes in size you just initiate an MPP migration project and move to one of the proven enterprise MPP solutions. No one heard about the “unstructured” data – if you got to analyze logs just parse them with Perl/Python/Java/C++ and load into you analytical DBMS. And no one heard about high velocity data – simply use traditional OLTP RDBMS for frequent updates and chunk them for insertion into the analytical DWH.
