BigQuery data specification

Note
This is a third-party integration and is not an Optimizely subprocessor. See Optimizely's Third-Party Add-Ons & Platform Integration Terms.

This page describes the data schemas for Optimizely Experimentation data in BigQuery.

Decisions

Field	Type	Description
`uuid`	String	Event UUID generated by the client. Used to deduplicate events.
`timestamp`	Integer	Event timestamp (in UTC).
`account_id`	String	Account identifier.
`visitor_id`	String	A unique identifier for the visitor.
`session_id` **	String	Optimizely no longer automatically generates the `session_id` as of October 9, 2023.
`campaign_id`	String	The ID of the campaign containing this experiment.
`experiment_id`	String	The ID of the experiment the visitor was assigned to. For Personalization campaigns, explicitly send `null` as the `experiment_id` for visitors not bucketed into any experiment. This is required to accurately compute campaign reach.
`experiment_id_hash`	Integer	Integer-range partitioning column. Use `ABS(MOD(FARM_FINGERPRINT(experiment_id), 4000))` to filter queries by experiment ID.
`variation_id`	String	The ID of the variation the visitor was assigned to. For Personalization campaigns, explicitly send `null` as the `variation_id` for visitors not bucketed into any experiment. This is required to accurately compute campaign reach.
`user_ip`	String	User IP address.
`user_agent`	String	User-agent.
`anonymize_ip`	Boolean	When set to `true`, the last octet of the IP address is removed before storage. When `false`, the full IP address is stored. This setting is most relevant if your implementation runs in a web browser or mobile app and must comply with data privacy regulations. This flag is independent of the IP anonymization setting in Account and Project settings. If this flag is `true`, IP-based filtering does not work correctly, because anonymization occurs before IP filters are applied.
`referer`	String	HTTP referer (the page from which the event was sent).
`is_holdback`	Boolean	A boolean indicating if the visitor is bucketed into the experiment based on the traffic allocation settings. If set to `true`, the user was excluded from the experiment.
`client_engine`	String	Client engine string (for example, 'js' or 'node-sdk').
`client_version`	String	Client version.
`revision`	String	Client snippet revision.
`attributes`	array <id:String, type:String, value:String>	An array of user attributes (also known as segments).
`process_timestamp`	Integer	Timestamp set by the server. Indicates when the event was processed by the server (in UTC).

** Optimizely no longer automatically generates the session_id as of October 9, 2023, but you can add it manually. See the Experimentation Analytics October 2023 release notes.

Conversion

Field	Type	Description
`uuid`	String	Event UUID generated by the client. Used to deduplicate events.
`timestamp`	Timestamp	Event timestamp in UTC.
`account_id`	String	Account identifier.
`visitor_id`	String	A unique identifier for the visitor.
`session_id` **	String	Unique session ID. Optimizely no longer automatically generates the `session_id` as of October 9, 2023.
`entity_id`	String	Event entity identifier.
`event_type`	String	Event type (click, pageview, custom, or client_activation).
`event_name`	String	Human-readable event name from the client, or `multi-event` when multiple events are batched.
`project_id`	String	(Optional) Only pass `project_id` if you are using the Optimizely Recommendations product.
`revenue`	Integer	Revenue (in cents).
`value`	Float	The value used to compute value or numeric metrics.
`quantity`	Integer	Quantity metric value.
`user_ip`	String	User IP address.
`user_agent`	String	User-agent.
`anonymize_ip`	Boolean	When set to `true`, the last octet of the IP address is removed before storage. When `false`, the full IP address is stored. This setting is most relevant if your implementation runs in a web browser or mobile app and must comply with data privacy regulations. This flag is independent of the IP anonymization setting in Account and Project settings. If this flag is `true`, IP-based filtering does not work correctly, because anonymization occurs before IP filters are applied.
`referer`	String	HTTP Referer (the page from which the event was sent).
`client_engine`	String	Client engine string (for example, 'node-sdk').
`client_version`	String	Client version.
`revision`	String	Client snippet revision.
`attributes`	Array <id:String, name:String, type:String, value:String>	An array of user attributes (also known as segments).
`tags`	Map <key:String, value:String>	Key-value pairs of event tags.
`properties`	Map <key:String, value:String>	Key-value pairs defining properties of the event. The value must be a string.
`experiments` **	Array <campaign_id:String, experiment_id:String, variation_id:string, is_holdback:Boolean>	An array of the campaigns, experiments, and variations the event is attributed to. Optimizely no longer automatically generates the `experiments` field as of October 9, 2023.
`process_timestamp`	Integer	Timestamp set by the server. Indicates when the event was processed by the server (in UTC).

** Optimizely no longer automatically generates the session_id and experiments fields as of October 9, 2023. See the Experimentation Analytics October 2023 release notes.
