intarrow::GetCpuThreadPoolCapacity()#

Get the capacity of the global thread pool.

You can change this number usingSetCpuThreadPoolCapacity().

Statusarrow::SetCpuThreadPoolCapacity(intthreads)#

Set the capacity of the global thread pool.

Set the number of worker threads int the thread pool to which Arrow dispatches various CPU-bound tasks.

The current number is returned byGetCpuThreadPoolCapacity().

intarrow::io::GetIOThreadPoolCapacity()#

Get the capacity of the global I/O thread pool.

Return the number of worker threads in the thread pool to which Arrow dispatches various I/O-bound tasks. This is an ideal number, not necessarily the exact number of threads at a given point in time.

You can change this number usingSetIOThreadPoolCapacity().

Statusarrow::io::SetIOThreadPoolCapacity(intthreads)#

Set the capacity of the global I/O thread pool.

Set the number of worker threads in the thread pool to which Arrow dispatches various I/O-bound tasks.

The current number is returned byGetIOThreadPoolCapacity().
