Acero: A C++ streaming execution engine#


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

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.

Acero consumes streams of input data, transforms them, and outputs a stream of data.
