Read an Arrow table into an Atoti table.

<Note>
  This is just a shortcut for:

  ```python theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
  inferred_data_types = session.tables.infer_data_types(arrow_table)
  table = session.create_table(
      table_name,
      data_types={**inferred_data_types, **data_types},
      default_values=...,
      keys=...,
      partitioning=...,
  )
  table.load(arrow_table)
  ```

  The longer variant can be refactored to move the [`load()`](./atoti.Table.load#atoti.Table.load) call inside a [`data_transaction()`](./atoti.Tables.data_transaction#atoti.tables.Tables.data_transaction).
</Note>
