> The core uses a btree to keep a sorted structure for the nodes.
> The underlying implementation for the btree is the [google/btree|https://github.com/google/btree]. The repository has been archived and is no longer supported.
> Moving to a different implementation for a btree that is still supported is the correct thing.
> The simple replacement seems to be the [tidwall/btree|https://github.com/tidwall/btree]. Moving to the generics version inside that the implementation would also reduce memory overhead and improve performance.
