> The following operations where demanded by Jim Ma for his JOPR plugin work (and I agree that they are needed).
> 1. JobQuery : query by job id
> 2. query historyTasks by process definition id" .
> 3. The api to query the average process instance duration . I get this value by sum and divide the process duration . It will be faster if there is the same api as the get average activity duration.
> 4. The api to get the process deployment , process definition , process instances , task number . It can be retrieved by calling the collection size . It will be efficient to select count(*) from database .
