I'm new user of Pig , and I'm very interested in the architecture of Pig.
I have a question about the logical plan
In the logical plan of this example: (in attach)
a = load 'myfile';
b = filter a by $0 > 5;
store b into 'myfilteredfile';
Does all the data in 'myfile' will be sent in it's totality to the Proj(0)
operator and to the Filter Operator ??
More generally what are runing on the arrows in the logical plan ??
what is the best documentation to understand the architecture of Pig not
only how to use it because I'll try to use it in the medical domain but
first I have to understand it
thank you very much for your help
