Description
A successor project to my previous attempt at building a temporal graph database (https://news.ycombinator.com/item?id=23455516). This one builds on its predecessor's concept, but drops the dependency on another database to provide the storage, transaction and query engines. Minigraf is self-contained, packaged as a library crate, embeds into your application, and supports full bi-temporality.

Could you build this?
No Implementing a custom, self-contained bi-temporal graph database in Rust from scratch (including custom storage engine, ACID transactions, and temporal graph traversals) is a hard systems research and engineering problem.
What it would actually take: This requires designing an LSM-tree or B-tree based storage engine with an append-only WAL, MVCC concurrency control, and dual-timestamp indexing (valid time and transaction time). The team needs deep expertise in systems programming, memory mapping, lock-free data structures, and graph query optimization (handling cycle detection and temporal point-in-time / interval queries).
Discussion
10 comments analyzed.
Competitors mentioned: SQLite, PostgreSQL, Cypher-based databases
Concerns raised: Need for another custom database and query language, Existing graph/relational databases already handle use cases
