RQL Cleanup Configuration

When resource queries are no longer referenced, they should be deleted from the system.

The de.properties file contains the following resource query cleanup properties that can be used to configure when and how often resource queries are evaluated to determine which can be deleted:

  • ResourceQueryCleanerEnable - Enables, or disables, the evaluation of resource queries to identify those that are no longer referenced. If this is disabled (false), automatic deletion of un-referenced resource queries does not take place.
  • ResourceQueryCleanerStart - The time of day at which resource queries, that are no longer being used, are scheduled for deletion.

    Cleanup of unused resource queries is invoked at this time each day that cleanup is scheduled according to the value of ResourceQueryCleanerInterval.

  • ResourceQueryCleanerInterval - The interval between evaluations of resource queries to identify those that are no longer referenced, and can be deleted. This defaults to once per day (at the time specified in ResourceQueryCleanerStart).
  • ResourceQueryCleanerEnd - The time of day at which the last resource query evaluation of the queries that can be deleted will be accepted.
  • ResourceQueryCleanerLimit - The number of resource queries checked for deletion in a single database transaction.
  • ResourceQueryCleanerPause - The number of seconds between deleting batches of resource queries.
