Acero is experimental and a stable API is not yet guaranteed.
.. note::
If you are interested in contributing to Acero or learning about its
internals, please see the :doc:`Acero Developer's Guide<../developers/cpp/acero>`.
For many complex computations, successive direct :ref:invocation of compute functions <invoking-compute-functions> is not feasible
in either memory or computation time. To facilitate arbitrarily large inputs
and more efficient resource usage, the Arrow C++ implementation also
provides Acero, a streaming query engine with which computations can
be formulated and executed.
