Benchmarking Performance of camunda Process Engine - Broken SSDs and some Numbers

Written by Daniel Meyer on , under Execution category.
Yesterday morning I posted some details about our current performance testing efforts. At that point I was still developing the performance testing framework and using the H2 in-memory database when running tests, just to check whether everything runs clean. Yesterday evening, finally, I wanted to run some tests on a "real" database.  I hadn't done any serious performance testing since a couple of month back when we released camunda BPM 7.

Gaining insight into the Performance of camunda Process Engine

Written by Daniel Meyer on , under Execution category.
The camunda process engine has a very active codebase and is constantly evolving. Only last week we did a major refactoring, re-implementing the way the BPMN Boundary Event, Event Subprocess, Terminate End Event and similar constructs work. In summer we introduced an activity instance model and rewrote the history implementation, turning it into a fire-and-forget event stream. We also constantly add new features such as incidents and many others. When doing such refactorings, the extensive process engine testsuite gives us the confidence that we do not break existing functionality from a functional perspective (process engine currently has 1669 Testases, over 500 were added last year).

Get your Tasklist as RSS Feed

Written by Jakob Freund on , under Execution category.
I don't like watching my Tasklist all day. Getting email notifications for tasks that I should complete is nice, but sometimes I don't want to complete the task right after being notified but still need to keep in mind there is something pending. This is how I came to create a simple PHP script that exposes my tasks as an RSS Feed. I can use that in my personal master dashboard (Microsoft Outlook) to keep track of my camunda Tasklist.

camunda Modeler as a standalone tool

Written by Nico Rehwaldt on , under Execution category.
As a small little side project I was working on a standalone version of the camunda BPMN 2.0 modeling plugin for Eclipse. The camunda Modeler standalone offers nice little features to better integrate with the operating system and focuses 100% on process modeling. It is available for Mac, Linux and Windows. Update (2014-02-05) The project is now an official part of camunda BPM. Read the offical announcement or check out its home on camunda.

How to use Generated Task Forms with camunda BPM - Screencast

Written by Daniel Meyer on , under Execution category.
I prepared a screencast in which I show how to use the Generated Task Forms Feature we introduced with camunda BPM 7.1.0-alpha1. Generated task forms allow you to create simple task forms without the need to write any HTML code. Please also have a look at the Generated Task Forms Quickstart. I dedicate the first 3 minutes to show you guys how to do the project setup. If you are familiar with setting up a camunda ServletProcessApplication, you can skip ahead to about 3:00 and start there.
