Subject Re: Storing images in Hbase
Date Fri, 11 Jan 2013 00:40:44 GMT
Been there, done that... kind of an interesting problem... 

Someone earlier said that HBase isn't good for images.  It works pretty well, again it depends
on the use case.

Your schema is also going to play a role and you're going to have to tune things a little
differently because when you pull an image, you're pulling a larger chunk of data as well
as you want to make sure you can fit a decent number of images within a region. 


How are you planning on using the images? Are you going to run a M/R job and see if you can't
spot landmarks and businesses in a photo? Language translations? 
Or just a repository?
