Deprecate FlowAsyncOperation and reimplement public versions FlowExternalOperation and FlowExternalAsyncOperation. await added to FlowLogic to allow easy calling from both Java and Kotlin. There are two overrides of await (one for FlowExternalOperation and FlowExternalAsyncOperation). Implementations of FlowExternalOperation return a result (written as blocking code) from their execute function. This operation will then be executed using a thread provided by the externalOperationExecutor. Implementations of FlowExternalAsyncOperation return a future from their execute function. This operation must be executed on a newly spawned thread or one provided by a thread pool. It is up to developers to handle threading in this scenario. The default thread pool (externalOperationExecutor) can be configured through the flowExternalOperationThreadPoolSize node config. The current implementation leaves FlowAsyncOperation alone, meaning that any developers that have used it (even though it is internal) won't need to change their apps. If this was not concern I would delete it completely and replumb the state machine code. Instead, it has been marked with @DoNotImplement and executeAsync is annotated with @Deprecated |
