How to handle large datasets? Should we store the data somewhere on the cloud/ out of grasshopper?

Keeping the data in grasshopper makes it very slow to work with data. I am wondering if we really need to have the ttl graph in grasshopper? What about serializing it, keep it somewhere on the cloud, and deserialize it just if its needed?
We don't really need to see the ttl format the whole time, right? We can deserialize it to TTL if needed.
We can work with the graph data in GraphDB environment, and grasshopper can be used just to support the process to create this graph database.
