Subject streaming window operations
Date Fri, 27 Mar 2015 20:36:20 GMT
Looking at the window operators, I see things like sum, min, max but they're always for a
single 'field'.Is there an easy way to do stats like min, max, average on a window but on
many different fields at once?Should I split the stream into many parallel streams with single
fields to achieve that? it sounds like it would be more efficient to parse the many fields
and do the stats in parallel within the same stream, I guess then with a customer window operator
Your thoughts on this?Thanks
