Hi everybody!  
Considering +/- of moving lots of temporal sensor data to dgraph.  
The data structure is simple:

- sensor\_id: i
- timestamp: t
- measurement: v

Shall I reflect the same structure in the graphql schema ( `type Measurement {i, t, v}` ) or there are better ways to structure/store such kind of data for optimal dgraph performance?  
What are the best practices here?

I think for your case the entity is straightforward.

```auto
type Measurement {
    sensor_id: ID!
    timestamp: DateTime
    measurement: String
}

```

You can now get your hands dirty, there is nothing complex that you need to do. Unless you have a bigger goal and more entities to relate to. And in general, all existing practices in the GraphQL community apply to Dgraph’s GraphQL.
