Micah Kornfield commented on ARROW-6206:
----------------------------------------
"is there a charter for what java usecases will be supported, and THEN, what
among these items will leverage NIO, and what among these can use pure heap
implementations of objects exclusively?"
I don't fully understand this question. My best attempt to answer it below:
The system property is needed because we use Netty as an off-heap memory
allocator, this could potentially be replaced with something JNI based.
The core of the current Java implementation is off-heap memory. If you have
specific requirements/use-cases in mind discussing dev@ or user@ mailing list
is probably the way to go.
Could you provide a link to the text you quoted I'd be interested in reading it.
