Once you complete the Profile Builder CLI steps, you will be able to see the Profiles project on your machine.

Site configuration file

RudderStack creates a site configuration file (~/.pb/siteconfig.yaml) while creating a warehouse connection. It contains the following details including secrets (if any):

Warehouse connection details and its credentials.
Git repository connection credentials (if any). Follow the below steps to add the same:
1. Generate the SSH Key.
2. Associate the SSH key to your Git project.
3. Add private key as credentials in the siteconfig.yaml file under key field in the gitcreds field.

If you have multiple Profiles projects and they use different warehouse connections, you can store the details for multiple connections in the same site configuration file.

A sample site configuration file containing multiple warehouse connection details is shown below:

connections:
  # connection name
  prod-db-profile:
      target: dev
      outputs:

RudderStack recommends defining two target within a single connection: one for dev/staging and the other for production. For example, refer to the connection named prod-db-profile in the sample file above. The default target is set to dev, as specified by the target key. To change the output to production, you can run pb run -t prod.

Profiles project structure

The following image shows the folder structure of the project:

`README.md`

The README.md file provides a quick overview on how to use PB along with SQL queries for data analysis.

`pb_project.yaml`

The pb_project.yaml file contains the project details like the name, schema version, warehouse connection, entityEntity refers to a digital representation of a class of real world distinct objects for which you can create a profile. names along with ID types, etc.

A sample pb_project.yaml file with entity type as user:

# Project name

The following table explains the fields used in the above file:

Field	Data type	Description
`name`	String	Name of the project.
`schema_version`	Integer	Project’s YAML version. Each new schema version comes with improvements and added functionalities.
`connection`	String	Connection name from `siteconfig.yaml` used for connecting to the warehouse.
`model_folders`	String	Names of folders where model files are stored.
`entities`	List	Lists all the entities used in the project for which you can define models. Each entry for an entity here is a JSON object specifying entity’s name and attributes.
`packages`	List	List of packages with their name and URL. Optionally, you can also extend ID types filters for including or excluding certain values from this list.
`python_requirements`	List	Constraint your Profiles project to run only on specific version(s).

`entities`

Field	Data type	Description
`name`	String	Name of the entity used in the project.
`id_stitcher`	String	Profiles project includes an ID stitcher model (`default_id_stitcher`) by default even if you do not define any specs for creating one. To create a custom ID stitcher model, you can use the `id_stitcher` field and pass its path as the value (for example, `models/name_of_id_stitcher`).
`id_types`	List	List of the identifier types you want the `id_stitcher` model to consume, process, and stitch together. You can further define filters on these id types.
`feature_views`	List	(Optional) Lists all the view names along with their ID’s being served for feature view model.

The identifiers listed in id_types may have a many-to-one relationship with an entity but each ID must belong to a single entity.
For example, a user entity might have id_types as the salesforce_id, anonymous_id, email, and session_id (a user may have many session IDs over time). However, it should not include something like ip_address, as a single IP can be used by different users at different times and it is not considered as a user identifier.

filters

You can filter out the ID types you do not want to include in the stitching process by using the filters field.

For example:

If email is an ID type but you have internal testing emails you want to filter out, you can define those here.
If you want to exclude all the blacklisted email addresses, you can create an input model (for example, csv_email_blacklist) with CSV file as a source, that contains all such email addresses.
If you want to exclude all the user_ids, you can create an SQL model (for example, sql_exclusion_model) that contains a specific logic to enlist all such IDs.

Field	Data type	Description
`type`	String	Type of filter. Allowed values are `include` or `exclude`.
`value`	String	Value to match, for example, you can reject certain invalid ID values like `NaN`, `unknown`, `test@domain.com`, etc.
`regex`	String	Regular expression with which to match the values.
`sql`	List	SQL statement with `select` and `from` keys.

`packages`

You can import library packages in a project signifying where the project inherits its properties from.

Field	Data type	Description
`name`	String	Specify a name.
`url`	String	HTTPS URL of the lib package, with a tag for the best schema version.

Models folder

Models folder contains all the input sources your Profiles project will consume and process.

Whenever you create a Profiles project using pb init pb project, the default inputs.yaml and profiles.yaml are created in the Models folder.

`inputs.yaml`

The inputs.yaml file contains the configuration for all the input sources which Profiles uses to run models and create outputs like the ID graph, feature view, etc. You can also define specific constraints on the input sources using the contract key.

RudderStack supports the following input sources:

Table: Specify the table’s name in the table key.
View: Specify the view’s name in the view key.
S3 bucket: Specify the path of the CSV file in your bucket in the s3 key. See Use Amazon S3 bucket as input for more information.
Local CSV file: Specify the file path in the csv key. See Use CSV file as input for more information.

You can also specify the table/view along with the column name and SQL expression for retrieving values. The input specification may also include metadata and the constraints on those columns.

A sample inputs.yaml file:

inputs:
    # name of the input source
  - name: salesforceTasks
    contract:
      is_optional: false
      is_event_stream: true
      with_entity_ids:

      occurred_at_col: activitydate
      row_identifier:
        - activitydate
        - whoid

        - select: "whoid" 
          type: salesforce_id
          # entity to which the id belongs
          entity: user

        - name: context_traits_email
        - name: user_id
    app_defaults:
      table: autotrack.pages
      # For BigQuery, it is recommended to use view (view: _views_<view_name>) instead of table for event streaming data sets.
      occurred_at_col: timestamp
      ids:
        - select: "anonymous_id"
          type: rudder_anon_id
          entity: user
          to_default_stitcher: true
        # below sql expression check the email type, if it is gmail and yahoo return email otherwise spilt email return domain of email.  
        - select: "case when lower(coalesce(context_traits_email, user_id)) like any ('%gmail%', '%yahoo%') then lower(coalesce(context_traits_email, user_id))  \
              else split_part(lower(coalesce(context_traits_email, user_id)),'@',2) end"
          type: email
          entity: user
          to_default_stitcher: true

The following table explains the fields used in the above file:

Field	Data type	Description
`name`	String	Name of the input model.
`contract`	Dictionary	A model contract provides essential information about the model like the necessary columns and entity IDs that it should contain. This is crucial for other models that depend on it, as it helps find errors early and closer to the point of their origin.
`app_defaults`	Dictionary	Values that input defaults to when you run the project directly. For library projects, you can remap the inputs and override the app defaults while importing the library projects.

`contract`

Field	Data type	Description
`is_optional`	Boolean	[Optional] Whether the model’s existence in the warehouse is mandatory. Default value: False
`is_event_stream`	Boolean	[Optional] Whether the table/view is a series/stream of events. A model that has a `timestamp` column is an event stream model. Default value: False
`with_entity_ids`	List	List of all entities with which the model is related. A model M1 is considered related to model M2 if there is an ID of model M2 in M1’s output columns.
`with_columns`	List	List of all ID columns that this contract is applicable for.

`app_defaults`

Field	Data type	Description
`table`/`view`	String	Name of the warehouse table/view containing the data. You can prefix the table/view with an external schema or database in the same warehouse, if applicable. Note that you can specify either a table or view but not both.
`s3`	String	Name of the CSV file in your Amazon S3 bucket containing the data.
`csv`	String	Name of the CSV file in your local storage containing the data. The file path should be relative to the project folder.
`occurred_at_col`	String	Name of the column in table/view containing the timestamp.
`row_identifier`	String	(Optional) List of all the identifiers whose combination acts as a primary key. If the unique row exists already during the run process while creating a copy of the input table, it is not copied again.
`ids`	List	Specifies the list of all IDs present in the source table along with their column names (or column SQL expressions). Note: Some input columns may contain IDs of associated entities. By their presence, such ID columns associate the row with the entity of the ID. The ID Stitcher may use these declarations to automatically discover ID-to-ID edges.

`ids`

Field	Data type	Description
`select`	String	Specifies the column name to be used as the identifier. You can also specify a SQL expression if some transformation is required. Note: You can also refer table from another Database/Schema in the same data warehouse. For example, `table: <database_name>.<schema_name>.<table_name>`.
`type`	String	Type of identifier. All the ID types of a project are declared in `pb_project.yaml`. You can specify additional filters on the column expression. Note: Each ID type is linked only with a single entity.
`entity`	String	Entity name defined in the `pb_project.yaml` file to which the ID belongs.
`to_default_stitcher`	Boolean	Set this optional field to `false` for the ID to be excluded from the default ID stitcher. Default value: True

`profiles.yaml`

The profiles.yaml file defines the Profiles semantic models. Each model (defined in model_type field) is a prepackaged SQL model that takes your inputs and runs in the warehouse to output the defined views and tables.

You can define the entity_vars/input_vars under var_groups which are used to create the output tables.

The following profiles.yaml file defines a group of vars named vars_list and a user_profile model:

var_groups:
  name: vars_list
  entity_key: user # This is the name defined in project file. If we change that, we need to change the name here too.
  vars:
    - entity_var:
        name: is_mql
        select: max(case when salesForceLeadsTable.mql__c == 'True' then 1 else 0 end)
        from: inputs/salesForceLeadsTable
        description: Whether a domain is mql or not
    - entity_var:
        name: blacklistFlag
        select: max(case when exclude_reason is not null then 1 else 0 end)
        from: inputs/blacklistDomains
        where: (context_sources_job_run_id = (select top 1 context_sources_job_run_id from blacklistDomains order by timestamp desc))
        is_feature: false
    - entity_var:
        name: ignore_domain
        select: case when {{user.Var("blacklistFlag")}} = 1 or {{user.Var("domainSummary_account_type")}} like '%free%' then 1 else 0 end
        description: Whether a domain should be ignored for the analysis
    - entity_var:
        name: salesEvents
        select: json_agg(activitydate, case when (type='Email' or tasksubtype = 'Email') then case when lower(subject) like '%[in]%' then 'sf_inbound_email' \
              else 'sf_outbound_email' end when macro(call_conversion) then 'sf_call' else null end as event)
        from: inputs/salesforceTasks
        description: Salesforce touches are converted to one of following events - sf_inbound_email, sf_outbound_email, sf_call, null
        is_feature: false
    - entity_var:
        name: webhookFormSubmit
        select:  min(timestamp)
        from: inputs/webhookSource
        where: variable_1 is null and timestamp < sales_conversion_timestamp and timestamp > var('start_date')
models:
  - name: user_profile
    model_type: feature_table_model
    model_spec:
      validity_time: 24h # 1 day
      entity_key: user

`var_groups`

Field	Data type	Description
`name`	String	A unique name for the var_group.
`entity_key`	String	The entity to which the var_group belongs to.
`vars`	Object	This section is used to specify variables, with the help of `entity_var` and `input_var`. Aggregation on stitched ID type is done by default and is implicit.

Optionally, you can create models using the above vars. The following fields are common for all the model types:

Field	Data type	Description
`name`	String	Name of the model. Note that a table with the same name is created in the data warehouse. For example, if you define the name as `user_table`, the output table will be named something like `Material_user_table_<rest-of-generated-hash>_<timestamp-number>`.
`model_type`	String	Defines the type of model. Possible values are: `id_stitcher`, `feature_table_model`, `sql_template`, `entity_cohort`, `id_collator`, `python_model`, `feature_view`, etc. See model types for more infromation.
`model_spec`	Object	Defines the detailed configuration specification for the target model.

macros.yaml

You can optionally use macros - reusable functions that encapsulate complex processing logic directly within the SQL expression. See Macros for more information on their usage.
