Hello Jenkins,
I'd like you to reexamine a change. Please visit
https://asterix-gerrit.ics.uci.edu/1214
to look at the new patch set (#2).
Change subject: Updated DeletableFrameTupleAppender to support reusing index
slots.
......................................................................
Updated DeletableFrameTupleAppender to support reusing index slots.
The new appender uses a eight bytes per tuple, but allows the frame to
reuse tuple index slots after a tuple as been deleted. When the use case
has many tuples added and removed from a frame, the new appender better
utilizes the tuple index slots. Where the old method would continue to
take more slot for each new tuple, the new model will reuse delete tuple
index slots.
