Why are Rinda TupleSpace bin's LIFO?

Hi! It seems that TupleSpace bin’s are Last In First Out (LIFO). Is there a reason why they are not instead First In First Out (FIFO)?

def find(&blk)
  @bin.reverse_each do |x|
    return x if yield(x)
  end
  nil
end

Hi, José.

I asked Seki san.

Apparently it’s result of the performance tuning. When you are dealing with lots of tuples (eg: 100,000), then deleting from the bottom of Array makes operation faster.

If you want to guarantee the order, then you can either pass the index number (as explained in page 130), or could use Drip.

Thanks.
