The +[dataset macro](###dataset) will compile based on the provided [activity +macros](###activity-source) and the [relationship macros](##relationships). It +can then be nested in a CTE in a dbt-Core model. Eg: +```c +// my_first_dataset.sql + +with + +dataset_cte as ( + {{ dbt_activity_schema.dataset( + activity_stream_ref = ref("example__activity_stream"), + + primary_activity = dbt_activity_schema.activity( + dbt_activity_schema.all_ever(), "bought something"), + + appended_activities = [ + dbt_activity_schema.activity( + dbt_activity_schema.first_before(), "visited page"), + dbt_activity_schema.activity( + dbt_activity_schema.first_after(), "bought item"), ] - ) -}} + ) }} +) + +select * from dataset_cte + +``` +> Note: This package does not contain macros to create the Activity Stream +> model. It derives Dataset models on top of an existing Activity Stream model. + +### Configure Columns +This package conforms to the [Activity Schema V2 +Specification](https://github.com/ActivitySchema/ActivitySchema/blob/main/2.0.md#entity-table) +and, by default, it expects the columns in that spec to exist in the Activity Stream model. + +#### Required Columns +In order for critical joins in the [dataset macro](###dataset) to work as +expected, the following columns must exist: + - **`activity`**: A string or ID that identifies the action or fact + attributable to the `customer`. + - **`customer`**: The UUID of the entity or customer. Must be used across + activities. + - **`ts`**: The timestamp at which the activity occurred. + - **`activity_repeated_at`**: The timestamp of the next activity, per + customer. Create using a lead window function, partitioned by activity and + customer. + - **`activity_occurrence`**: The running count of the actvity per customer. + Create using a rank window function, partitioned by activity and customer. +#### Mapping Column Names +If the required columns exist conceptually under different names, they can be +aliased using the nested `activity_schema_v2_column_mappings` project var. Eg: + +```yml +# dbt_project.yml + +... + +vars: + dbt_activity_schema: + activity_schema_v2_column_mappings: + # Activity Stream with required column names that + # differ from the V2 spec, mapped from their spec name. + customer: entity_uuid + ts: activity_occurred_at + +... +``` + +#### Included Dataset Columns +The set of columns that are included in the compiled SQL of the [dataset +macro](###dataset-source) can be configured using the nested +`default_dataset_columns` project var. Eg: +```yml +# dbt_project.yml + +... + +vars: + dbt_activity_schema: + # List columns from the Activity Schema to include in the Dataset + default_dataset_columns: + - activity_id + - entity_uuid + - activity_occurred_at + - revenue_impact + +... ``` -See the signature in the macro for more details on each parameter. + +These defaults can be overriden using the `override_columns` argument in the +[activity macro](###activity-source). + +#### Configure Appended Activity Column Names +The naming convention of the columns, in the activities passed to the +`appended_activities` argument can be configured by overriding the +[generate_appended_column_alias](./macros/utils/generate_appended_column_alias.sql) +macro. See the dbt docs on [overriding package +macros](https://docs.getdbt.com/reference/dbt-jinja-functions/dispatch#overriding-package-macros) +for more details. + +## Macros +--- +### dataset ([source](macros/dataset.sql)) +Create a derived dataset using self-joins from an Activity Stream model. + +**params:** +- **`activity_stream_ref (required)`** : [ref](https://docs.getdbt.com/reference/dbt-jinja-functions/ref) + + The dbt `ref()` that points to the activty stream model. + +- **`primary_activity (required)`** : [activity](###activity) + + The primary activity of the derived dataset. + +- **`appended_activities (optional)`** : List [ [activity](###activity) ] + + The list of appended activities to self-join to the primary activity. + +### activity ([source](macros/activity.sql)) +Represents either the primary activity or one of the appended activities in a +dataset. + +**params:** +- **`relationship (required)`** : [relationship](##relationships) + + The relationship that defines how the activity is filtered or joined, + depending on if it is provided to the `primary_activity` or + `appended_activities` argument in the dataset macro. + +- **`activity_name (required)`** : str + + The string identifier of the activity in the Activity Stream.

Can + optionally contain the python f-string placeholders `{primary}` and + `{appended}` in the string. These placeholders will be compiled by the + [dataset macro](./macros/dataset.sql) with the correct SQL aliases for the + joins between the primary activity and the appended activity. + + Eg: + ```python + "json_extract({primary}.feature_json, 'dim1') = + json_extract({appended}.feature_json, 'dim1')" + ``` + The `{primary}` and `{appended}` placeholders compile according to + the cardinality of the activity in the `appended_activities` list + argument to `dataset.sql`. + + Compiled: + ```python + "json_extract(stream.feature_json, 'dim1') = + json_extract(stream_3.feature_json, 'dim1')" + ``` + Given that the appended activity was 3rd in the `appended_activities` list + argument. + +## Relationships +See the [relationships/](macros/relationships/) path for the most up to date +relationships and their documentation. ## Contributions -Contributions and feedback are welcome.
