ral::execution::task_result do_process(std::vector<std::unique_ptr<ral::frame::BlazingTable>> inputs, std::shared_ptr<ral::cache::CacheMachine> output, cudaStream_t stream, const std::map<std::string, std::string> &args) override
virtual kstatus run() override

Executes the batch processing. Loads the data from their input port, and after processing it, the results are stored in their output port.
