Acero: A C++ streaming execution engine

Warning

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 Acero Developer’s Guide.

For many complex computations, successive direct invocation of 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.
