BigQuery - August 1st, 2016 [Change]



## Change When [loading Avro files](, BigQuery no longer creates an unnamed root-level column named "root." To ease the transition to this new schema, projects with the following contents are exempted from this change through a project override: * Projects that contained federated tables based on Avro files as of August 1, 2016 * Projects that have queried or loaded Avro files in the 30 days prior to August 1, 2016 All affected project owners will be notified and provided the option to remove the project override.
