 Hyracks Applications
 
   The Hyracks platform provides users the ability to execute jobs on a cluster. Jobs in Hyracks are expressed as a DAG of Operators and Connectors. Prior to being able to execute jobs on a Hyracks cluster, the code that implements the operators and connectors used in the jobs must be installed on the nodes of the cluster. The unit of deployment of code onto the cluster is called an application. Once an application containing the required code is created, multiple jobs can be executed against it until it is destroyed. A Hyracks cluster can have multiple applications installed simultaneously.
