I'm afraid you will need to explain in more detail what you are trying to do and what results you are expecting to get. Some operations in Arrow-C++ (which pyarrow uses) will take advantage of multiple threads. These operations are controlled by the functions you mentioned. Mostly today this is in file parsing and decoding. On the other hand, some functions are implemented completely in python (and thus subject to the GIL) and others are implemented in C++ and release the GIL but do not use multiple threads. -- This is an automated message from the Apache Git Service.
