Hello!

As far as I have read the forums of Map-reduce, it is basically used to
process large amount of data speedily. right??

But, can you please give me some instances or examples wherein, I can use
map-reduce..???

A very common one is processing large quantities of log files and producing
summary date.
Another use is simply as a way of distributing large jobs across multiple
computers.
In a previous job, we used Map/Reduce for distributed bulk web crawling, and
for distributed media file processing.
