> Currently, the read buffer allocation and output file creation of sort-shuffle is performed by the main thread. These operations are a little heavy and can block the main thread for a while which may influence other RPC calls including follow-up task deployment. This ticket aims to solve the issue by moving read buffer allocation and output file creation to setup method.
