load just certain fields from a map?

Is it possible to load just a few fields from ChukwaStorage or do I have to load the entire map then project just the fields I want?

Doesn’t help the MAP situation though I think.

Cheers

You can specify the field names to load by creating new instance of
ChukwaStorage like:

new ChukwaStorage('field1','field2'...);

Hope this helps.
