Enhance query API with operations needed for JOPR plugin -------------------------------------------------------- Key: JBPM-2543 URL: https://jira.jboss.org/jira/browse/JBPM-2543 Project: jBPM Issue Type: Feature Request Security Level: Public(Everyone can see) Affects Versions: jBPM 4.1, jBPM 4.0 Reporter: Joram Barrez Priority: Minor Fix For: jBPM 4.x 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 .
