Lars Hofhansl commented on PHOENIX-5120:
----------------------------------------
Also, I'd like to avoid renaming the classes - even though they're not using
MappedByteBuffers anymore. Any comment on that.
[~tdsilva], [~abhishek.chouhan], [~apurtell], FYI.
> Avoid using MappedByteBuffers for server side sorting.
