Jay Zhuang commented on CASSANDRA-9989:
---------------------------------------
Sorry, I misunderstood the last part. I updated the patch to evenly split the
values to all child nodes. The TREE_SIZE is starting from index 0 instead of 1.
{{left}} is replaced with an incrementing counter, please review:
|branch | [9989|https://github.com/cooldoger/cassandra/tree/9989]|
{{LongBTreeTest.java}} is timing out even for trunk, I'm increasing timeout and
run through the test.

> BTree.Builder could reduce its copying, and exploit toArray more efficiently,
> with some work. It's not very important right now because we don't make as
> much use of its bulk-add methods as we otherwise might, however over time
> this work will become more useful.
