Interface changes / additions

  • Adding autodetect property on LoadTableFromStorageJob to enable schema autodetection. (#3648)
  • Implementing the Python Futures interface for Jobs. Call job.result() to wait for jobs to complete instead of polling manually on the job status. (#3626)

  • job_name argument added to Table.upload_from_file for setting the job ID. (#3605)
  • Adding google.cloud.bigquery.dbapi package, which implements PEP-249 DB-API specification. (#2921)
  • Adding Table.view_use_legacy_sql property. Can be used to create views with legacy or standard SQL. (#3514)
