Kyvos supports both ROLAP and HOLAP on BigQuery connections. You can use this connection for querying data from your BigQuery data warehouse.
| Info |
|---|
InfoIf you implement a filter on a date column with >= or <= and explicit type cast, you must add the kyvos.rf.sqlparser.enabled propertyand set its value to true at the Hadoop connection. You can create multiple BigQuery connections for raw data querying. The connections are available on the Dataset designer page, where you can select the connection to be used for a particular semantic model.
See the Working with non-materialized or raw data semantic models section for more details. All Spark-supported functions must be mapped according to supported BigQuery functions. You must update the SQL and datasets with supported BigQuery functions. Otherwise, the incompatible functions would fail. You can connect to your BigQuery data warehouse for reading data from both GCP and EMR-based AWS clusters. You can create multiple read connections using different BigQuery data warehouse accounts from different projects. You can then use datasets from all these BigQuery warehouses in a single relationship and hence a single semantic model. If you intend to create multiple datasets from different warehouses in different projects, ensure all the Materialization Datasets specified when configuring the Connections belong to the same region.

From the Toolbox, click Setup, then Connections. From the Actions menu ( ⋮ ) click Add Connection. Enter a name or select it from the Connection list. Select Warehouse from the Category List.
There may be more than one warehouse connection. For Providers, select BigQuery. Specify the Server to access Google APIs. For example, https://www.googleapis.com. Specify the Port to use. Enter your Google Project ID for the Google Cloud Platform. To generate Temporary Views in Separate Dataset when performing the validation/preview operation from Kyvos on Google BigQuery, provide the Materialization Project and Materialization Dataset names. From the Authentication Type, select Application Default Credentials option. By default, Is Read checkbox is selected as this connection can only be used to read data (creating registered files) on which the cube will be created. Click Properties to configure advanced settings. For example, to enable Views in BigQuery set the value for viewsEnabled as true. Click the Test button from the top left to validate the connection settings. If the connection is valid, click the Save button.
