Space/disk occupied by run time and history tables per process instance in DB

Hi ,

What is the size of DB or # of bytes occupied by runtime and history tables (with FULL history) per process instance? The BPMN is just ~9KB and process variables are just simple json of 500 bytes.
Camunda is hosted in separate pod. And process start via REST API and all service tasks are handled via external task. We do have 2 wait state in this process.

This information is needed for our DB sizing in prod and performance/load testing in perf environment.


Hi @sarahegde,

just setup your designated environment, complete a fixed number of process instances and measure the usage from the database.

This simulator ( helps you to generate some load on the engine.

Hope this helps, Ingo
