I am developing an application that is currently based on mysql. I believe it will require significant scaling and so I am exploring hadoop.
I know nothing about map-reduce and am trying to figure out how it conceptually relates to simple things like CRUD. I guess I am just looking for a document or some simple explanation of how you use the map-reduce metaphor to do basic index, search, sort, insert type things. Any info and pointers greatly appreciated. Hank
