Field Detail

enableEagerExecutionTreeFetching

protected boolean enableEagerExecutionTreeFetching

If true, whenever an execution is fetched from the data store, the whole execution tree is fetched in the same roundtrip. Less roundtrips to the database outweighs doing many, smaller fetches and often multiple executions from the same tree are needed anyway when executing process instances. This enables the setting globally. However, it must also be enabled on a process definition itself. If false, the setting on the process definition is ignored.

enableExecutionRelationshipCounts

protected boolean enableExecutionRelationshipCounts

Keeps a count on each execution that holds how many variables, jobs, tasks, event subscriptions, etc. the execution has. This makes the delete more performant as a query is not needed anymore to check if there is related data. However, maintaining the count does mean more updates to the execution and potentially more optimistic locking opportunities. Typically keeping the counts lead to better performance as deletes are a large part of the execution tree maintenance. This property can only be enabled or disabled globally currently.

enableTaskRelationshipCounts

protected boolean enableTaskRelationshipCounts

Similar to enableExecutionRelationshipCounts, but on the task level. Keeps count of how many variables ad identity links the task has.

validateExecutionRelationshipCountConfigOnBoot

protected boolean validateExecutionRelationshipCountConfigOnBoot

If false, no check will be done on boot.

validateTaskRelationshipCountConfigOnBoot

protected boolean validateTaskRelationshipCountConfigOnBoot

If false, no check will be done on boot.

enableLocalization

protected boolean enableLocalization

Experimental setting: in certain places in the engine (execution/process instance/historic process instance/ tasks/data objects) localization is supported. When this setting is false, localization is completely disabled, which gives a small performance gain.
