Understanding the difference between `_id` and `id` in GraphQL

What's the difference between

_id

and

id

when using graphql?

I'm pretty sure the difference is, that "id" is automatically generated no matter what. With "_id" you can define it yourself - but if you do not do that, it will be auto generated as well.

Gotcha, OK thanks

_id

is the document field that comes from Sanity and

id

is the node id that Gatsby generates :)
