Solving Santa’s Sequencing Problem Using Domain Narrowing Constraint Propagation Based on DMN collect hit policies.

Written by Rob Parker, Enterprise Architect, Australia Post on , under Community category.

CamundaCon 2019 is just around the corner! Rob Parker, Enterprise Architect at Australia Post, will be presenting Innovative Problems For Elegant Solutions and he’s shared with us a sneak peak at the kind of out-of-the-box thinking his presentation will cover:

Everybody is likely familiar with Sudoku puzzles. When I solve them, I typically use little pencil marks to track which values are still feasible in unresolved cells. In other words, for each unresolved cell, I annotate it with the set of remaining possible values or its domain. As each cell is solved, the implication is propagated to its neighbouring cells by crossing off the infeasible values (domain narrowing) from each set of candidate values. This technique is effectively a form of constraint propagation with domain narrowing.

How to Find NullPointerExceptions for Process Variables During Build Time

Written by Sascha Di Bernardo on , under Community category.
The viadee Process Application Validator (vPAV) was released well over a year ago on GitHub in order to check the interplay of models and code as part of a CI build. Since then vPAV has gained traction and more features were developed. It also provides extensibility to create your own set of checkers. The major release version 3.0.0 comes with many new features, such as a revamped HTML report, inheritance of rules, multiple instantiations of checkers with varying configurations, remote location of process models, multi-language support and most of all a reworked ProcessVariableModelChecker (see release notes).

The Journey of Camunda BPM Asserts: From Extension to Platform

Written by Niall Deehan on , under Community category.

For the people who have been in any way involved with the Camunda Community the last few years, this is unlikely to be the first time you’ve heard the name Martin Schimak. Also if you’re a developer using Camunda, chances are that, perhaps unbeknownst to you - you’ve been greatly helped by some of the projects that Martin has created and released as open source extensions for the platform. Having people like Martin as part of the Camunda Community is an important factor to the success and adoption of the Open Source platform, so I wanted to talk to Martin about how he came to be such a positive influence on the project. Perhaps learning from him how to encourage others out there to do the same. I spoke with him specifically about the camunda-bpm-asserts library that he, along with Rafael Cordones and other contributors created, and how he feels about it being recently added as a supported part of the Camunda platform.

We will address some common configurations and provide some building blocks you can tailor to your particular needs. Skill level: Intermediate You’ve used Kubernetes before. If not, why not try a tutorial and spin up your first cluster? Authors Alastair Firth is a Senior Site Reliability Engineer on the Camunda Cloud team.

Camunda BPM - Session Management in Cloud Environments

Written by Lars Lange on , under Community category.
In the last few years we’ve noticed many of our users are migrating from bare-metal infrastructures to cloud-based ones. While the cloud has overcome several limitations of the traditional infrastructure, other problems arise when deploying your microservices in environments that have the possibility to scale up and down dynamically based on workload. When deploying Camunda BPM, the first problem that you will encounter will be, most probably, session management.While this is easily solvable in traditional environments by using sticky sessions, the same solution does not apply when you deal with cloud environments like, Kubernetes.
