Go Client

Overview

Go client attempts to follow Go language conventions. The conversion of a Go program to the fault-oblivious workflow function is expected to be pretty mechanical.

Cadence requires determinism of the workflow code. It supports deterministic execution of the multithreaded code and constructs like select that are non-deterministic by Go design. The Cadence solution is to provide corresponding constructs in the form of interfaces that have similar capability but support deterministic execution.

For example, instead of native Go channels, workflow code must use the workflow.Channel interface. Instead of select, the Selector interface must be used.
