Delete selected version of a process definition

[engineering-issue-sync-app]

Value Proposition Statement

Delete Process Definition to free up storage, declutter user interface and prevent errors.

User Problem

• I have multiple versions of Process Definitions that are not being used anymore. I cannot delete them, what can cause accidentally start process in the older version.
• A bloated database of process data, takes too much space
• I cannot stop creation of the new process instances, when there is a timer start event (cycle)
• Currently, there is no way to delete process definition form Zeebe cluster
• During development, I have multiple versions with bugs as I was testing the process

User Stories

• As a Developer, I can delete a selected version of deployed process definition without running instances and all process instances finished of this version (1 operation) via Operate UI and Zeebe API.
• As a Developer, while using this feature, I can read basic information, what will be deleted
• As a Developer, I can see the progress of deletion in Operations Panel
• As a Developer, I can read the documentation, explaining what is going to happen when I delete a version of process definition
• As a Product manager, I know how many times process definition was deleted

Implementation Notes

• Together with Process Definition deletion, all dependent data of this process definition version like tasks and decision instances will be deleted - only instances, not definitions. It will affect only child processes, call activity and business rule tasks - nothing in parent instances.
• With this iteration, we'll deliver simplified frontend - the enhancements will be covered in the 4th iteration.
