How to query process instances by page
this question is a bit vague. Could you elaborate that a bit, please? Especially which tool you’re referring to?
For example, I query the process whose bpmnprocessid is ABC, and I query it in pages with 20 pages per page
Zeebe itself does not support querying for process instances, but instead offers exporters to other tools (like Elastic Search) which can be queried. This question is answered in more detail here: Why doesn’t Zeebe support an API to query for active instances?
Hope this helps.
