      Description

      A key component in eliminating the 2GB limit on blocks is creating a proper abstraction for storing more than 2GB. Currently spark is limited by a reliance on nio ByteBuffer and netty ByteBuf, both of which are limited at 2GB. This task will introduce the new abstraction and the relevant implementation and utilities, without effecting the existing implementation at all.
