Subject [jira] [Commented] (CRUNCH-538) Add support for Java lambdas to PCollection/PTable methods
Date Sat, 01 Aug 2015 11:47:04 GMT


Gabriel Reid commented on CRUNCH-538:

Oh, just noticed this two-week-old comment here, I guess I missed it previously.

+1 to the idea of having a the FnContext object as parameter to a lambda.

And about the IFilterFn/FIlterFn thing, avoiding a need to recompile stuff sounds fine to
me, and this is a change we could always do in the future if desired.

> Java 8 is more-or-less mainstream at this point, and lambdas are one of its best new
features. Let's add lambda-friendly interfaces and methods to the PCollection/PTable classes
modeled after the methods defined for Scrunch.
