Hey @desp.kaz,
You’ve created posts around the multi tenancy. Are the replies to Multitetancy with different database servers answering the questions you have here?
And indeed as you have seen from Multi-Schema Process and Event Registry Engine Advice - #4 by chaserb, we do not support the Multi Tenancy Process Engine Configuration with our Spring Boot starters. If you need something like that, then you’ll need to configure that on your own.
Cheers,
Filip
