Hi Kefu and Adam,
curious whether we have reliable enough set of numbers on how spatially
efficient btree allocator is? I recall some Adam's comment in the PR
showing 2x saving in BTree allocator vs. AVL on.
But the data set there seems to be relatively small - total consumed RAM
is just a few MBs. Anything else available?
I recall Adam promised to run more vast testing at perf meeting....
Thanks,
Igor

hi Adam,
while looking at Hybrid Allocator [0] and the newly introduced Btree
Allocator [1], i am wondering if we still need the bitmap allocator to
cap the memory usage due to the large overhead of AVL allocator?
because btree is much more spatially efficient than AVL tree.
cheers
