I initially tried using Memgraph but faced stability issues and a lack of flow control tools during traversal, making it impossible to load one month’s worth of Ethereum blockchain data. The current solution, however, handles 10 times more data hosted on the same machine.

ClickHouse is an excellent database, provided you don't need to traverse graphs. Graph traversal requires many queries, and frequent disk interactions can significantly degrade performance.
