  Or they choose a horizontally-scalable architecture, a la TitanDB. Btw, anyone knows how such solutions handle cross machine traversals? Are they schema-based? So the DB knows how to manage data locality and efficient joins/traversals?

    I don't know about Neptune -- curious to hear what it is based on -- but TitanDB never really supported cross-machine traversals for the execution engine. The data was stored in a distributed fashion (across say a Cassandra cluster), but any instance of the execution engine was single-machine, with no easy way to talk between multiple instances of the execution engine.

      One database service that supports horizontally scaled graphs is Azure CosmosDB Graph API: https://docs.microsoft.com/en-us/azure/cosmos-db/graph-introduction https://docs.microsoft.com/en-us/azure/cosmos-db/graph-intro... Worth to take a look if you need a managed Gremlin solution with some degree of global distribution.
