Enterprise Integration Patterns - Message Filter

Overview

A Message Filter is a special form of a Content-Based Router. It examines the message content and passes the message to a service only if the message content matches certain criteria, otherwise the message is discarded.

Use Cases

Selective Processing


If a consumer wishes to receive only messages whose content satisfy a given criteria, a message filter can be inserted on the message path to filter out unwanted messages. The consumer can focus on processing the requests it expects and does not have the overhead of processing each incoming message and discarding those it is not interested in processing

Message Filterinng


Messages with sensitive/private content can be passed through only to authorized services and hidden from services which should not be receiving them.
