Gearpump can run on top of YARN as a YARN application. Gearpump‘s ApplicationMaster provides the application management , deployment and scheduling of DAG’s after arbitrating and receiving container resources from YARN
Storm and spark streaming are proven platforms, there are many production deployments. Compared with them, Gearpump is not than proven and there is no production deployment yet. However, there is no single platform that can cover every use case; Gearpump has its own +1 points in some special fields. As an instance, for IOT use cases, Gearpump may be considered convenient because the topology can be deployed to edge device with feature of location transparency. For another example, when users want to upgrade the application online without service interruption, Gearpump may be suitable as it can dynamically modify the computation DAG on the fly. For other special use cases that are suitable for Gearpump, please check section What is a good use case for Gearpump
The name GearPump is a reference the engineering term “Gear Pump”, which is a super simple pump that consists of only two gears, but is very powerful at streaming water from left to right.
We are looking into a hands of candidate for what a good DSL should be. Akka stream API is one of the candidates.
The ultimate goal is to make it an Apache project.
