Camunda Rest Engine memory usage

Hi Team,

We have an use case to keep the process instances open for infinite time. I would like to check with you if we create process instances but not close them, does it have any impact on the memory usage (RAM) on the server. In our case, monthly we are creating around 2k to 5k new cases.

Please let us know if there is any relation between no. of active process instances and memory usage, does Camunda keeps any process data on memory?

Thanks in Advance,
Ravi

Processes are persisted in the DB. There should be no lingering memory usage. Memory would be used during executions such as execution tasks/jobs, etc. If you processes are idle then memory would not be a issue.

If you are deploying a lot of process definitions the deployment cache would increase in size and use more memory. (controllable through config)
