Purge Process
Purge process deletes stream data that is earlier than a specified time. This kind of process has the same intention as Purge command in TimeBase Administrator but with all advantages of aggregator process.
caution
Purge processes can now only be configured to run on a schedule. Legacy processes that were previously set to run on reboot or manually will no longer execute; they must be updated with a valid cron schedule to resume execution
To create a new Purge process in the QuantServer Architect interface, follow these steps:
- Edit Aggregator Processes: right-click the Aggregator box and select Edit Processes.
- New Purge Process: Select the New... drop-down menu and select New Purge Process. This will open a separate configuration window used to define the purge process.

If a process is in an active stage (i.e., it is running or scheduled for execution), it is displayed as working with a red square icon.
