We even offer a BPMN modeling tool, standalone and as eclipse plugin. Since BPMN is such a great modeling notation, we want more: Modeling BPMN should be easier and more convenient. There is no need to download and install software, when you can just open your browser and start modeling….

Use the source view to see what is behind the graphical representation or to edit custom attributes….

The new camunda BPMN model API

As already mentioned in our last alpha release blog post we are currently working on a BPMN model API to parse, create, edit and write BPMN 2.0 XML files. Last Friday we opened our GitHub repository and have since then created a userguide and some quickstarts.   The BPMN model API offers you a simple and straightforward way to interact with an BPMN 2.0 model. It enables you to gather information from an existing model, edit and extend them. Of course you can also create completely new ones. Technically the model API is based on a DOM layer which is accessed and manipulated by a general XML API developed by us. On top of this, the BPMN model API encapsulates the interaction…

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

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 7.0 Final and in the meantime I have switched my operating system from Windows 7 to Ubuntu Linux. Turns out that Linux is much more serious when it comes to I/O errors and broken SSDs. But more on that later. Let’s start with some numbers.   Some Numbers We ran…

Gaining insight into the Performance of camunda Process Engine

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 incidentsand 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 1669Testases, over 500 were added last year). On top of that, we put quite some effort into database migration testing, making sure that you can…
