⚠ BREAKING CHANGES

  • backends: Columns with Ibis date types are now returned as object dtype containing datetime.date objects when executing with the pandas backend.
  • impala: Direct HDFS integration is removed and support for ingesting pandas DataFrames directly is as well. The Impala backend still works with HDFS, but data in HDFS must be managed outside of ibis.
  • api: replace ibis.show_sql(expr) calls with print(ibis.to_sql(expr)) or if using Jupyter or IPython ibis.to_sql(expr)
  • bigquery: nullifzero is removed; use nullif(0) instead
  • bigquery: zeroifnull is removed; use fillna(0) instead
  • bigquery: list_databases is removed; use list_schemas instead
  • bigquery: the bigquery current_database method returns the data_project instead of the dataset_id. Use current_schema to retrieve dataset_id. To explicitly list tables in a given project and dataset, you can use f"{con.current_database}.{con.current_schema}"
