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.
