It is possible to the send data the of a Substreams to a subgraph, thus creating a Substreams-powered Subgraph.
There are two ways of making Substreams sink to a subgraph, it is really a matter of where you put your logic, in the subgraph or the Substreams.
Substreams Triggers: Consume from any Substreams module by importing the Protobuf model through a subgraph handler and write all your transformations using AssemblyScript. This method creates the subgraph entities directly in the subgraph.
Substreams Graph-Out: By writing the subgraph entities into Substreams, you can consume the module's output directly into graph-node. You will create a graph_out module that emits an EntityChanges Protobuf. The subgraph will read the EntityChanges object and consume the data directly.
Having more of your logic in Substreams benefits from a parallelized model and a cursor to never miss data, whereas triggers will be linearly consumed in graph-node.
