My perspective is that writing this kind of system in a language such as Python is actually a great thing because for myself Python is more widely readable and approachable compared to C++ or C which is what databases are often programmed in. If someone wants to be serious they can port it to a low level language . As it stands it's educational and useful for studying.
I wrote a distributed pseudo multi model SQL/graph Cypher/Document and dyanmodb style database in Python https://GitHub.com/samsquire/hash-db for the same goal of learning how database engines could work in a distributed way.
