>
> UpdateAttribute does a lot of work in every onTrigger() that it doesn't need
> to.
> The default actions map can be built at schedule time so that it doesn't need
> to be done on every trigger.
> getPropertyValue() can be implemented using ConcurrentMap.computeIfAbsent()
> Update actions can be ignored if there is a delete action for the same
> attribute.
> Only need to call processSession.updateAttributes() and
> processSession.deleteAttributes() if there are attributes to update and
> delete respectively.
