Hi Adam,
1- We have a JakartaEE application that we want to integrate with a business process tool, What do you think of Kogito in comparison with Camunda for the externalization of the business logic in a BPMN process and executing the workflow.
2- For the storage we are planning to use Minio as an Object storage solution, have you any recommandation of the best for the integratation, as developing a separated microservice who manages the storage , or dealing directly with the API.
Thanks

Hello Adam,

Any thoughts about using scripting languages in your application.
We would like to allow users to define small scripts like custom validations that could be modified on runtime.

Our plan is to use GraalVM and it's JavaScript engine. Do we have any other viable options? Have you ever tried something like this?
