⚠ BREAKING CHANGES

  • udf: The schema parameter for UDF definition has been removed. A new catalog parameter has been added. Ibis uses the word database to refer to a collection of tables, and the word catalog to refer to a collection of databases. You can use a combination of catalog and database to specify a hierarchical location for the UDF.
  • pyspark: Arguments to create_database, drop_database, and get_schema are now keyword-only except for the name args. Calls to these functions that have relied on positional argument ordering need to be updated.
  • dask: the dask backend no longer supports cov/corr with how="pop".
  • duckdb: Calling the get or contains method on NULL map
    values now returns NULL. Use coalesce(map.get(...), default) or
    coalesce(map.contains(), False) to get the previous behavior.
  • api: Integer inputs to select and mutate are now always interpreted as literals. Columns can still be accessed by their integer index using square-bracket syntax.
  • api: strings passed to table.mutate() are now interpreted as
    column references instead of literals, use ibis.literal(string) to
    pass the string as a literal
  • ir: Schema.apply_to() is removed, use ibis.formats.pandas.PandasConverter.convert_frame() instead
  • ddl: We are removing the word schema in its hierarchical
    sense. We use database to mean a collection of tables. The behavior of
    all *_database methods now applies only to collections of tables and
    never to collections of database (formerly schema)
  • CanListDatabases abstract methods now all refer to
    collections of tables.
  • CanCreateDatabases abstract methods now all refer to
    collections of tables.
  • list_databases now takes a kwarg catalog.
  • create_database now takes a kwarg catalog.
  • drop_database now takes a kwarg catalog.
  • current_database now refers to the current collection of tables.
  • CanCreateSchema is deprecated and create_schema, drop_schema,
    list_schemas, and current_schema are deprecated and redirect to the
    corresponding method/property ending in database.
  • We add a CanListCatalog and CanCreateCatalog that can list and
    create collections of database, respectively.
    The new methods are list_catalogs, create_catalog, drop_catalog,
  • There is a new current_catalog property.
  • api: timecontext feature is removed
  • api: The by argument from asof_join is removed. Calls to asof_join that previously used by should pass those arguments to predicates instead.
  • cleanup: Deprecated methods and properties op, output_dtype, and output_shape are removed. op is no longer needed, and use .dtype and .shape respectively for the other two.
  • api: expr.topk(...) now includes null counts. The row count of the topk call will not differ, but the number of nulls counted will no longer be zero. To drop the null row use the dropna method.
  • api: ibis.rows_with_max_lookback() function and ibis.window(max_lookback) argument are removed
  • strings: Backends that previously used initcap (analogous to str.title) to implement StringValue.capitalize() will produce different results when the input string contains multiple words (a word's definition being backend-specific).
  • impala: Impala UDFs no longer require explicit registration. Remove any calls to Function.register. If you were passing database to Function.register, pass that to scalar_function or aggregate_function as appropriate.
  • pandas: the timecontext feature is not supported anymore
  • api: on paremater of table.asof_join() is now only
    accept a single predicate, use predicates to supply additional
    join predicates.
