Temporal Integration

Question 1

Integration Pattern

Answer 1

A more typical approach is to have the Web or mobile app make calls to a service, such as a Web application that provides a REST endpoint, which acts as an application gateway.

For example, when a request is made to the endpoint associated with order processing, the code within that service can extract data from the HTTP request and use it as input to the Workflow when it calls the Temporal client’s execute workflow method. That in turn issues a gRPC request to the Temporal Cluster, which starts the Workflow Execution.

Question 2

Temporal SDK

Answer 2

You develop Temporal Workflows by writing code, using a standard programming language, similar to how you’d write any other type of application. This code will make calls to Temporal APIs, which in turn use a Temporal Client to communicate with the cluster. The library that provides support for this is called a Software Development Kit, or SDK.

Question 3

Java Dependency
