Struct PythonWorkerPool 

Source 
pub struct PythonWorkerPool { /* private fields */ }
Expand description

A persistent python3 worker that applies cloudpickled UDFs over Arrow IPC. One pool is shared by every Python UDF in an engine; access is serialized through the mutex (one in-flight batch at a time per worker).

Implementations§
