HBase Filters Explained: Let HBase Do the Data Selection Job for You
The naive approach that consists in getting all the required data at the Client in order to apply locally some processing should be limited in a distributed setting to trivial tasks operating on a tiny subset. There are two fundamentals reasons for that. First, this generates a lot of network exchanges, consuming without necessity a lot of resources and sometimes leading to unacceptable response time. Second, centralizing all the information then processing it, simply misses all the advantages brought by a powerful cluster of hundreds or even thousands machines. The lesson is simply: When you deal with BigData, the data center is your computer.
