> BTree is currently heavily used in our codebase, e.g., for primary index,
> deleted keys, inverted index etc. Most of BTrees of a dataset are immutable,
> as they are from disk components. However, our current codebase only has one
> version of mutable BTree, which has quite a number of overhead on
> locking/concurrency control during normal operations.
