PandasOnRayDataframePartition

PandasOnRayDataframePartition """""""""""""""""""""""""""""

The class is the specific implementation of :py:class:~modin.core.dataframe.pandas.partitioning.partition.PandasDataframePartition, providing the API to perform operations on a block partition, namely, pandas.DataFrame, using Ray as an execution engine.

In addition to wrapping a pandas.DataFrame, the class also holds the following metadata:

• length - length of pandas.DataFrame wrapped
• width - width of pandas.DataFrame wrapped
• ip - node IP address that holds pandas.DataFrame wrapped

An operation on a block partition can be performed in two modes:

• asynchronously_ - via :meth:~modin.core.execution.ray.implementations.pandas_on_ray.partitioning.PandasOnRayDataframePartition.apply
• lazily_ - via :meth:~modin.core.execution.ray.implementations.pandas_on_ray.partitioning.PandasOnRayDataframePartition.add_to_apply_calls
