:high_voltage: Breaking changes:

  • Because of security concerns, text tiles no longer support the form and input Markdown elements.

:star: Notable features:

  • For faster response time for queries in BigQuery, Looker will execute BigQuery queries by using jobCreationMode=JOB_CREATION_OPTIONAL. If BigQuery can return immediate results, it will run the query without creating a job, so the record in the Looker query history will have a BigQuery query ID instead of a BigQuery job ID. See the Understanding query performance metrics documentation page for more information about the BigQuery BI Engine metrics.

  • The Query Concurrency System Activity Explore is now available. This Explore can help you identify periods of high load and investigate performance bottlenecks that are related to database connection limits.

Check the release notes for more details. Happy Lookering!
