Camunda 8 - Self Managed Sizing

[vinothkumar]

Hi Team,
I would like to start my Camunda 8 self managed. I try to understand the memory allocation.
When I read below article. I got bit confused. Can someone help me on this ?

Sizing your environment | Camunda 8 Docs

As per my understanding everything will get stored in Elastic search in Camunda 8.
Below what is mean by workflow engine here ?
How data’s will get stored in workflow engine ?
where it is mentioned in the self-managed architecture diagram ?
What are the data’s will get stored here ?

“The workflow engine itself will store data along every process instance, especially to keep the current state persistent. This is unavoidable. In case there are human tasks, data is also sent to Tasklist and kept there, until tasks are completed.”

Hi @vinothkumar - the “workflow engine” is Zeebe. It stores data locally in a RocksDB instance, and that data is then exported to your long term data store via the exporter.
