It is called onceįor each virtual machine, at the end of the execution. The run() method, since this code is executed once at the beginning by each virtual machine.įor deinitialization purpose, the method cleanup() is available. To initialize expensive steps (such as opening external connections), you can write code outside Parameter is a type of execution context and provides access to the data and the iterator in The method run() is called for each input tuple (SCALAR) or each group (SET).
