About processors
Processors form the core of the Joule platform. A processor performs a distinct unique function when chained with others form a business use case
Overview
A use case core definition is based upon the processing pipeline. A pipeline is formed of one or more linked processors. This follows the functional programming paradigm whereby each processor performs a distinct process.
Events are processed in sequence with the final event either being presented to a select processor or directly to connected transports.
Available processor types
Joule has provided a number of core processors for developers to leverage to build domain use case. Processors can be categorised in to various functional grouping that reflect there purpose within the platform.
Observability and Metrics
Each OOTB processor record and presents event metrics to JMX monitoring platforms. This provides direct insight into how a streaming use case is performing.

Average processing latency
All of these metrics are enabled by default and presented as JMX beans on the standard monitoring ports.
