Mutiny

• Mutiny is a novel reactive programming library implementing the reactive stream API.
• We also have project reactor and RX Java As reactive programming libraries which are widely used and a lot of projects integrate it.
• Mutiny aims to be very Simplistic and it’s tightly integrated into the Quarkus Framework.
• Every reactive API uses mutiny API.
• Quarkus is a modern cloud Native micro services framework.
• Quarkus is gaining A lot of popularity in cloud native environments.
• Quarkus Reactive engine is powered by eclipse vertex and Netty.
• Vertex Clients are made available using mutiny bindings.
• We can use mutiny directly with vertex aswell.
• Mutiny is independent library and does not depend on Quarkus or Vertex.
• Mutiny is built on top of three pillars
• Event Driven
• Enables being elastic, resilient, And responsive.
• API navigability
• Mutiny is quite different from “RX Java” And “Project React” reactive API libraries.
• Simplicity
• The functionality is limited to the basics and learning curve is smaller than RX Java and Project Director.
• It supports only two reactive types
• Multi
• Represents streams of 0-n items(Potentially unbounded)
• Uni
• Represents streams of Receiving either an item or a failure.
• Vertex uses futures and promises To be able to use this mutiny, API
• A mutiny generator is provided, which transforms the vertex core API’s, Vertex Web API’s, And so on into mutiny core API’s and mutiny web API’s.
• This is done by smallrye mutiny vertex bindings library.
• The bindings are available for all kinds of vertex modules And you can integrate it by specifying an artefact “smallrye-mutiny-vertex-<Module>.
• Module refers to a vertex module, such as coal, pg-client, Web client etc.
• The group ID is io.smallrye.reactive And all imports come from this group.
• A practical learning curve of mutiny can be as follows
• Create a simple UNI, example form mutiny UNI type.
• Create a simple multi example
• Integrate mutiny into vertex core and vertex web.
• Vertex web and vertex reactive, Postgres client And mutiny example
• Fully reactive from API to data store.
