Camunda BPM 7.2

• Performance / Scalability

• Tasklist

• Connectors / Data / Scripts / Templates

• CMMN

Performance / Scalability

• Camunda BPM is increasingly used in High-Load Situations• A „high-load situation“ starts at ~10 instantiated processes per Second

• Some Customers run Camunda with > 1,000 Process Instances per Second

• This means we continuously improve the performance and scalability• Execute process instances in a short amount of time

• Support load balancing in Clusters

• Prepare Camunda for alternative storage strategies (No SQL, In Memory etc.)

Camunda 7.1 (!) compared to JBoss jBPM 6

More Information: http://camunda.com/landing/whitepaper-camunda-jbpm

In our tests, Camunda‘s throughput was 10x – 30x higher than with JBoss jBPM.

Performance Improvements in 7.2

• Improved First Level Cache (throughput increased by up to 90%)

• Improved Load Balancing for Cluster Mode

• Log Level for History can be configured

• Minimize Risk of Deadlocks in High-Load Situations

What is Tasklist?

Tasklist 7.2

In collaboration with “ The tasklist is the central point of contact for

business users with the BPM platform and is therefore an essential component. The innovative implementation of the Camunda tasklist matches the DAB bank's web technology stack perfectly and saves extensive in-house development. The functionality is optimally aligned to the Camunda BPM platform and due to its flexible adaptability also fulfills the needs of a bank.Karl Brandner, Chief Architect

CamundaBackendREST

CamundaJavaScript Forms SDK

Your very own HTML 5 User Interface

Camunda JavaScript Forms SDK

• Greatly simplifies the implementation of task forms.

• You can directly bind Html form controls to process variables.

• The Forms SDK handles the fetching of the variable values from the process engine, type conversions and so on.

• The Forms SDK optionally integrates with AngularJS to take advantage of AngularJS form validation and other AngularJS goodies.

Camunda Zero-Code BPM Suites

Java Objekte in XML or JSON serialisieren

Camunda BPM

Database

Customer, Address

XML or JSON

Advantages:• Anyone can directly inspect Java objects in the database and Cockpit• It is easier to set up polyglot architectures (e.g. Java + Javascript)

Improved Handling of Data Formats

XML or JSON

Advantages:• Directly access XML or JSON within the process via APIs• No need to convert XML or JSON into Java Objects

Why Scripts and Templates are awesome

• No Java Code / Classes needed

• (Re-)deployment during runtime

• Can be versioned as part of the process definition

• Can be embedded inside the BPMN as well as referenced and maintained in standalone files

• Great performance thanks to compile & cache

Advanced Support for Scripting

Advanced Support for Templates

Scripts and Templates in the Process

In Listeners

As Conditions

As IO-Mappings

Connectors

Connectors

• Simple API for implementing Connectors as reusable Components

• Included with Camunda 7.2: SOAP and REST (both based on Apache HTTP Client)

• Fundamentally different approach than Zero-Code Suites:• Developer become more productive – it‘s not about „empowering Business

Analysts“• However not every developer speaks Java• Primary Target Group: IT divisions that want to provide a workflow

infrastructure for their organization (other IT teams)• Focus on API instead of Properties• Connectors can be used in different components, e.g. Java Delegates

A powerful combination

Data

Scripting

Example: Do I have to work today?

REST

JSON

Javascript

Simple REST Call

Start with Process Variable date

(e.g. via unit test)

Invoke REST Service that provides

holidays as JSON

Run Javascript that checks if date is a holiday and puts result as variable

holiday: true|false

Route based on holiday

Camunda BPM 7.2

• Performance / Scalability

• Connectors / Data / Scripts / Templates

• CMMN

CMMN 1.0

• Published by OMG in May 2014 as the BPMN-equivalent for „Cases“

• Targets „Activities that are not so predefined and repeatable, but instead depend on evolving circumstances and ad hoc decisions by knowledge workers regarding a particular situation, a case (see Davenport 1994 and 2005; and Van der Aalst 2005)”

• Typical Use Cases:• application and claim processing in insurance

• patient care and medical diagnosis in healthcare

• problem resolution in call centers

• invoice discrepancy handling
