Message Sampling Processor

The message sampling processor consumes messages from a specified message store and sends the messages to a sequence at a configured interval. This message processor does not ensure reliable messaging.

Message sampling processor parameters

Following are the parameters you can set when adding a message sampling processor:

Parameter Name	Description	Required
Name	The name of the message sampling processor.	Yes
Message Processor Provider	The name of the message processor provider.	Yes
Sequence	The sequence to which the message sampling processor injects consumed messages.	Yes
Message Store	The message store from which the message sampling processor consumes messages.	Yes
Processor State (`is.active`)	Activate (`true`) or Deactivate (`false`)	No. The default is Activate (`true`).
Sampling Interval (`interval`)	Interval in milliseconds in which processor consumes messages	No. The default value is 1000.
Sampling Concurrency (`concurrency`)	The number of messages the processor consumes at a time	No. The default is value is 1.
Quartz Configuration File Path (`quartz.conf`)	Quartz configuration file path. This properties file contains the Quartz configuration parameters for fine tuning the Quartz engine. More details of the configuration can be found at http://quartz-scheduler.org/documentation/quartz-2.x/configuration/ConfigMain.	No
Cron Expression (`cronExpression`)	Cron expression to be used to configure the retry pattern	No
