What are the differences between Neo4j and Memgraph?

• Neo4j is written in Java, while Memgraph is written in C++
• Neo4j stores data on-disk, while Memgraph is an in-memory database that focuses on stream data processing and real-time computations, aiming to execute tasks within the shortest possible timeframe
• Custom procedures in Neo4j should be implemented using Java, while Memgraph is primarily focused on the Python ecosystem
• Native support for machine learning
