meridiandb · personal · C++20 · sole author2024 - presentA database engine I am writing from scratch: row, columnar, vector, and graph storage under one transaction, security, and metadata plane, instead of running four systems and reconciling them in application code. Distributed-first in design, single-node correct in implementation. Early: the foundation layers and the architecture decisions exist, the storage engine does not yet. The point is to understand storage trade-offs by living with them.
