Camunda 8 is a very flexible platform. Whether you're looking to scale components of your workflow platform architecture in a modular manner, use various programming languages to execute different workflow steps or build custom connectors to easily connect to your enterprise systems, Camunda 8 offers the required flexibility.

To illustrate one area of flexibility, we built a custom Redis connector that can allow you to save some or all of your process instance variables within the open-source key-value store very easily. Here's a screen capture of the Redis connector being used in a Camunda 8 process model:

We like the ability to add custom icons to connectors, so you can visually - at a glance - see the purpose of a particular task in a process model. (You may want to zoom in to see the full process model above.)

The connector offers two fields for configuration, each of which takes either a comma or semicolon delimited list of variables. The first field - which takes precedence - allows you to specify a list of variables that you would like saved to the key-value pair (in JSON), and the second allows you to specify a list of variables that you don't want saved to the key-value pair, as shown below:
