Add Google BiqQuery Functions to Cognos Analytics

Hi IBM,

We are using Google BigQuery as one of the database sources to connect to Cognos Analytics on Cloud and using the packages to build reports and dashboards.

Currently, we have to manually type in the Google BigQuery functions in the Model, reports and it is impacting the performance of the reports because of query decomposition, local processing and possible performance issues.

If the functions are added to Cognos as a built-in function set then it is improve the performance of the reports which are using Google BigQuery datasources.

Please review this request to add the Google BigQuery as the vendor specific function set in IBM Cognos Analytics 11.0.13

    You can use any vendor function that returns data to Cognos in a data type that Cognos supports, even if it does not appear in the list of vendor specific functions in the expression editor UI.

    Hi - we do support Google BigQuery functions today. If you are getting query decomposition and local processing (even after upgrading to a version of 11.1.4 or later) it would be helpful to diagnose if there are other reasons contributing to this.

    It is recommended to be using versions >= CA 11.1.4 when using Google Biguery.

    Those releases were updated to reflect improvements Google made to Bigquery. Older CA releases, such as 11.0.13 would not contain reflect those changes, which can result in decomposition where compensation was necessary at that time.

    Many of the built-in functions and aggregates in Cognos Analytics automatically are generated in SQL constructs passed to Bigquery etc.
