 Julia `Dict` and `Set` data structures safely persisted to disk.
 
 All collections are backed by [LMDB](https://en.wikipedia.org/wiki/Lightning_Memory-Mapped_Database) - a super fast B-Tree based embedded KV database with ACID guaranties.
-As with other B-Tree based databases reads are generally faster than writes. LMDB is not an exception, although write performance is relatively good to (expect 1k-10k TPS).

-Care was taken to make the datastructures thread-safe. LMDB handles most of the locking well, we just have to serialise the writes to an LMDB Environment in julia so that
