Join the growing community of integration ninjas using Martini™ to integrate faster. Gloop eliminates the grunt work required when creating services for application and data integration, building APIs, and managing data. Gloop makes it easy to perform common development tasks such as mapping and transforming data, iterating over arrays, executing if-else and switch-case logic, invoking external code, running jobs in parallel, and so much more. Flux is Martini’s event based workflow engine for managing asynchronous workflows and event based triggers of Gloop microservices. With Flux you can invoke Gloop microservices sequentially, passing the output of one to the other, and/or in parallel, and Flux will maintain the state of each execution for you. Flux workflows are created visually by dragging Flux states onto a canvas and selecting the Gloop microservice you would like executed when the state is invoked.
