Jay Zhuang commented on CASSANDRA-9989:
---------------------------------------
Can I take this one?
I guess it could be done by implementing bulkloading
https://en.wikipedia.org/wiki/B-tree#Initial_construction instead of adding
value one by one
https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/utils/btree/TreeBuilder.java#L135
Is that the right direction?
[~benedict] Sorry to ping you again, it's appreciated if you could give me more
information.

> 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.
