Subject Question: collect action returning to driver
Date Fri, 05 Aug 2016 17:12:30 GMT
Rather this is a fundamental question:

Was it an architectural constraint that collect action always returns the results to the driver?
It is gobbling up all the driver’s memory ( in case of cache ) and why can’t we have an
exclusive executor that shares the load and “somehow” merge the results? If it were the
design, I am flummoxed.
