Package Configuration Variables​

This package utilizes a set of variables that are configured to recommended values for optimal performance of the models. Depending on your use case, you might want to override these values by adding to your dbt_project.yml file.

note
All variables in Snowplow packages start with `snowplow__` but we have removed these in the below tables for brevity.
tip
When modifying the session/user_identifiers or using session/user_sql in the unified package these will overwrite the domain_sessionid and domain_userid fields in tables, rather than being session/user_identifier as in the core utils implementation. This is for historic reasons to mitigate breaking changes. Original values for these fields can be found in `original_domain_session/userid` in each table.

Config Generator​

You can use the below inputs to generate the code that you need to place into your dbt_project.yml file to configure the package as you require. Any values not specified will use their default values from the package.

Warehouse and Tracker
Schema (dataset) that contains your atomic events
Database that contains your atomic events
Target name of your development environment as defined in your `profiles.yml` file
The name of the table that contains your atomic events
Page ping heartbeat time as defined in your tracker configuration
Minimum visit length as defined in your tracker configuration
The users module requires data from the derived sessions table. If you choose to disable the standard sessions table in favor of your own custom table, set this to reference your new table e.g. {{ ref("snowplow_unified_sessions_custom") }}

The maximum allowed number of days between the event creation and it being sent to the collector
The number of hours to look before the latest event processed - to account for late arriving data, which comes out of order

Output Schemas​

By default all scratch/staging tables will be created in the <target.schema>_scratch schema, the derived tables, will be created in <target.schema>_derived and all manifest tables in <target.schema>_snowplow_manifest. Some of these schemas are only used by specific packages, ensure you add the correct configurations for each packages you are using. To change, please add the following to your dbt_project.yml file:

tip

If you want to use just your connection schema with no suffixes, set the +schema: values to null
