Integrate

Build History

Integrate is a Ruby Integration Framework for building messaging systems following the Pipes and Filters architectural style.

Using Integrate you can define a workflow to divide a large processing task into a sequence of smaller, independent processing steps that are connected by channels.

Concepts

Messages

A Message is a generic container for data consisting of headers and a payload. Headers hold commonly required information (e.g. id and timestamp), and the payload can be any object. Messages are immutable.

Channels

A Channel represents the "pipe" of a Pipes and Filters architecture. Producers send Messages to a Channel, and Consumers receive Messages from a Channel. A Channel decouples the messaging components.

Endpoints

An Endpoint represents the "filter" of a Pipes and Filters architecture. Its role is to connect application code to the messaging framework and to do so in a non-invasive manner.

Transformers

A Transformer allows loose-coupling of Endpoints. Transformers can be added between Endpoints so that no Endpoint needs to know what is expected by the next in a workflow. A Transformer is responsible for converting a Message's content or structure and returning a new, modified Message.

Filters

A Filter determines whether a Message should be passed to its output channel based upon the value of a Message's headers and/or payload.

Routers

A Router decides which Channel should receive a Message next (if any), based upon the value of a Message's headers and/or payload.

Splitters

A Splitter accepts a Message and then splits it into multiple Messages. A common use case is dividing a "composite" payload object into a group of Messages containing the sub-divided payloads.

Aggregators

An Aggregator is the opposite of a Splitter. It receives multiple Messages and combines them into a single Message.

Service Activators

A Service Activator connects an external service instance to the messaging system.

Channel Adapters

A Channel Adapter connects a Channel to an external system or transport. They may be either inbound or outbound.
