+sidebar_label: Seed Scripts
+---
+
+While developing it's often useful to be able to have fake data available in the database. Fake data can help with building the UI and save you time when trying to get the GraphQL query correct. Super Graph has the ability do this for you. All you have to do is write a seed script `config/seed.js` (In Javascript) and use the `db:seed` command line option. Below is an example of kind of things you can do in a seed script.
+
+## Creating fake users
+
+Since all mutations and queries are in standard GraphQL you can use all the features available in Super Graph GraphQL.
+
+```javascript
+var users = [];
+
+for (i = 0; i < 20; i++) {
+  var data = {
+    slug: util.make_slug(fake.first_name() + "-" + fake.last_name()),
+    first_name: fake.first_name(),
+    last_name: fake.last_name(),
+    picture_url: fake.avatar_url(),
+    email: fake.email(),
+    bio: fake.sentence(10),
+  };
+
+  var res = graphql(" \
+	mutation { \
+		user(insert: $data) { \
+			id \
+		} \
+	}", { data: data });
+
+  users.push(res.user);
+}
+```
+
+## Inserting the users fake blog posts
+
+Another example highlighting how the `connect` syntax of Super Graph GraphQL can be used to connect inserted posts
+to random users that were previously created. For futher details checkout the [seed script](/seed) documentation.
+
+```javascript
+var posts = [];
+
+for (i = 0; i < 1500; i++) {
+  var user.id = users[Math.floor(Math.random() * 10)];
+
+  var data = {
+    slug:       util.make_slug(fake.sentence(3) + i),
+    body:       fake.sentence(100),
+    published:   true,
+    thread: {
+      connect: { user: user.id }
+    }
+  }
+
+  var res = graphql(" \
+  mutation { \
+    post(insert: $data) { \
+      id \
+    } \
+  }",
+  { data: data },
+  { user_id: u.id })
+
+  posts.push(res.post.slug)
+}
+```
+
+## Insert a large number of rows efficiently
+
+This feature uses the `COPY` functionality available in Postgres this is the best way to
+insert a large number of rows into a table. The `import_csv` function reads in a CSV file using the first
+line of the file as column names.

 You can generate the following fake data for your seeding purposes. Below is the list of fake data functions supported by the built-in fake data library. For example `fake.image_url()` will generate a fake image url or `fake.shuffle_strings(['hello', 'world', 'cool'])` will generate a randomly shuffled version of that array of strings or `fake.rand_string(['hello', 'world', 'cool'])` will return a random string from the array provided.

 ### Migrations
 
 Easy database migrations is the most important thing when building products backend by a relational database. We make it super easy to manage and migrate your database.

+
+Having observability and telemetry is at the core of any production ready service. Super Graph has built-in support for OpenCensus for tracing requests all the way from HTTP to the database and providing all kinds of metrics.
+
+OpenCensus has a concept called exporters these are external services that can consume this data and make to give you graphs, charts, alerting etc. Super Graph again has built-in support for Zipkin, Prometheus, Google Stackdriver and the AWS X-Ray exporters.
+
+## Telemetry config
+
+The `telemetry` section of the standard config files is where you set values to configure this feature to your needs.
+
+```yaml
+telemetry:
+  debug: true
+  interval: 5s
+  metrics:
+    exporter: "prometheus"
+    endpoint: ""
+    namespace: "web api"
+    key: "1234xyz"
+  tracing:
+    exporter: "zipkin"
+    endpoint: "http://zipkin:9411/api/v2/spans"
+    sample: 0.2
+    include_query: false
+    include_params: false
+```
+
+**debug**: Enabling debug enables an embedded web ui to test and debug tracing and metrics. This UI called `zPages` is provided by OpenCensus and will be made available on the `/telemetry` path. For more information on using `zPages` https://opencensus.io/zpages/. Remeber to disable this in production.
+
+**interval**: This controls the interval setting for OpenCensus metrics collection. This deafaults to `5 seconds` if not set.
+
+**metric.exporters** Setting this enables metrics collection. The supported values for this field are `prometheus` and `stackdriver`. The Prometheus exporter requires `metric.namespace` to be set. The Sackdriver exporter requires the `metric.key` to be set to the Google Cloud Project ID.
+
+**metric.endpoint** Is not currently used by any of the exporters.
+
+**tracing.exporter** Setting this enables request tracing. The supported values for this field are `zipkin`, `aws` and `xray`. Zipkin requires `tracing.endpoint` to be set. AWS and Xray are the same and do not require any addiitonal settings.
+
+**tracing.sample** This controls what percentage of the requests should be traced. By default `0.5` or 50% of the requests are traced, `always` is also a valid value for this field and it means all requests will be traced.
+
+**include_query** Include the Super Graph SQL query to the trace. Be careful with this setting in production it will add the entire SQL query to the trace. This can be veru useful to debug slow requests.
+
+**include_params** Include the Super Graph SQL query parameters to the trace. Be careful with this setting in production it will it can potentially leak sensitive user information into tracing logs.
+
+## Using Zipkin
+
+Zipkin is a really great open source request tracing project. It's easy to add to your current Super Graph app as a way to test tracing in development. Add the following to the Super Graph generated `docker-compose.yml` file. Also add `zipkin` in your current apps `depends_on` list. Once setup the Zipkin UI is available at http://localhost:9411
+
+```yaml
+  your_api:
+    ...
+    depends_on:
+      - db
+      - zipkin
+
+  zipkin:
+    image: openzipkin/zipkin-slim
+    container_name: zipkin
+    # Environment settings are defined here https://github.com/openzipkin/zipkin/blob/master/zipkin-server/README.md#environment-variables
+    environment:
+      - STORAGE_TYPE=mem
+      # Uncomment to enable self-tracing
+      # - SELF_TRACING_ENABLED=true
+      # Uncomment to enable debug logging
+      # - JAVA_OPTS=-Dorg.slf4j.simpleLogger.log.zipkin2=debug
+    ports:
+      # Port used for the Zipkin UI and HTTP Api
+      - 9411:9411

+Super Graph comes with a build-in GraphQL editor that only runs in development. Use it to craft your queries and copy-paste them into you're app once you're ready. The editor supports auto-completation and schema documentation. This makes it super easy to craft and test your query all in one go without knowing anything about the underlying database structure.
+
+You can even set query variables or http headers as required. To simulate an authenticated user set the http header `"X-USER-ID": 5` to the user id of the user you want to test with.
