Build a Graph Database

Build a graph database like Neo4j/Memgraph: nodes + edges + properties storage, index-free adjacency for O(1) traversal, label/property indexes, Cypher-style query language, BFS/Dijkstra/PageRank algorithms, RDF triples and SPARQL alternative model, and the engine behind Twitter's social graph, fraud detection, and knowledge graphs.
