Exactly at what point you want to run your custom code?  We have hooks at points like opening
a scanner at a region, closing scanner at a region, calling next (pre/post) etc

Subject: Co-Processor in scanning the HBase's Table

Hi there
I wanna use a custom code after scanning a large table and prefer to run
the code after scanning each region.I know that I should use
co-processor,but don't know which of Observer,Endpoint or both of them I
should use ? Is there any simple example of them ?

Tnx
