Message Store Maintenance
The ThinkAutomation Server will automatically remove old processed messages from the Message Store database. The date at which a processed message is removed is defined by the Keep Messages For Days setting on the Solution properties (which defaults to 1095 days). This will affect messages processed by all Automations within the Solution.
Use the Edit Solution Properties button on the Ribbon to change this setting.
Set the Keep Messages For Days option to zero to disable automatic deletion.
The ThinkAutomation Server performs message store maintenance on a daily basis based on the times specified in the Server Settings - Message Store - Run Message Store Database Maintenance At setting. When Automations or Solutions are deleted via the Studio, ThinkAutomation marks the messages in the message store for deletion during the next maintenance run.
Messages in the Message Store provide an audit trial of messages processed. To maintain best performance you should only keep processed messages for a long as you need to.
