Customer question: Are there any plans to support nested fields in BigQuery (array is not supported right now) and make the structs representation more user friendly? Answer from Brian Mearns:“At this time any nested, explode, flatten functionality is best handled by the JDBC interface layer and underlying database. We have NO intentions to work on auto-unpacking the various nested levels of structs, maps, arrays during 2022 Q3 or Q4.”
