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 On 6/25/2021 11:35 AM, Kefu Chai wrote:
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
