Hi Team,
We are using Pig intensively in our various projects. We are doing
optimizations for that we wanted to know how join works. Though we have
moved to Skewed joins for some of our use cases.
At many places in the documentation this is mentioned that in join data is
streamed for second table. But I was identify how this can fit in map
reduce paradigm.
1. Can anyone please clarify how join happens in pig.
2. What is the meaning of Streaming here? Are we loading the files
directly
in the reducres?
Regards,
Gagan
