Prisma

Hey <!everyone> :v: :prisma-cool:

We just released Prisma <https://github.com/prisma/prisma/releases/tag/3.2.0|3.2.0> :prisma-rainbow:

:female-detective: *MongoDB introspection support is now in Preview*
In this version, we introduce support for introspecting MongoDB databases. If adding Prisma to an existing project, running `prisma db pull` against a MongoDB database with _existing data_ will sample the data and create a Prisma data model based on the stored documents.

This comes with a few caveats:
• The preview feature `mongoDb` must be enabled on the `datasource` block in the Prisma schema.
• The MongoDB instance must have at least one collection with at least one document.
• To introspect indices, there must be at least one document in the collection with the indexed fields.
• If any fields have conflicting types, the most common type is chosen and the other types are written to a comment above the field in the Prisma schema.
• Relations must be added manually after introspection.
• Running `prisma db pull` multiple times will overwrite any added text in the data model for now.

We're constantly iterating on this feature, so please provide <https://github.com/prisma/prisma/issues/8241|feedback> for introspecting MongoDB databases!

:1234: *Get the count of a relation in MongoDB*
This release, we're giving MongoDB developers the ability to query the count of a relation. In the example below, we're getting the number of posts each user wrote:
```const userWithPostsCount = await prisma.user.findMany({
  include: {
    _count: {
      select: { posts: true },
    },
  },
})

// =&gt; [
//      { 
//        email: "<mailto:alice@prisma.io|alice@prisma.io>",
//        _count: { posts: 3 }
//      }
//    ]```
This feature was previously available for SQL databases and now it's also available in MongoDB. Learn more in our <https://www.prisma.io/docs/concepts/components/prisma-client/aggregation-grouping-summarizing/#count|documentation>.
