Overview

It allows to define pipelines that transform hash values.

Each pipeline is bound to a particular key and processes a value related to that key. A pipeline consists of a chain of actions that are executed one by one. An actions receives a value from a previous action and is expected to return successful or failed result. A successful result contains a new value being the result of the processing. The new value is passed further in the chain to the next action. A failed result contains a message from an action saying why a particular value can’t be processed. Following actions in the chain are not executed.
