Interface OptimizingTriggerCreator
- All Known Implementing Classes:
OptimizingTriggerCreatorImpl
public interface OptimizingTriggerCreator
Adds recompute triggers to objects in an optimized way:
- The triggers are set to a given time in future (e.g. 1 minute from now).
- If more requests to create triggers to the same object come before that time comes (minus some safety margin,
e.g. 2 seconds), their creation is skipped.
Currently we deal only with the recompute triggers. Other types can be added as necessary.
The deduplication works best if:
- the requests are of the same kind (i.e. either name-based or OID-based);
- the triggers are created on a single node, because the creators share a common state which is node-wide.
But even if these conditions are not met, the extra triggers creation is still avoided, at the cost of extra
read operations against the repository.
