Acero - Streaming Execution Engine

.. warning::

Acero is experimental and a stable API is not yet guaranteed.

Acero is a streaming query engine, which allows the computation to be expressed as an "execution plan" (constructed using the :class:Declaration interface). This enables to create a computation composed of pyarrow.compute functions and to execute this efficiently in a batched manner.
