Activiti scaling

I have a system with 1 application server and about 50 database schemas. Each schema has different workflows. Is that possible to use with Activiti? Or is Activiti intended to be used with only 1 database schema per server?

My question goes towards resources:

* will Activiti remain in memory for each of the 50 database schemas and hence consumes a lot of memory or is it only instantiated on demand and then after e. g. a workflow is processed the memory is freed?
* will Activiti keep the database connections open and could I be running into problems that there are no more connections?

Or are there other recommendations to set up such kind o system?

Thank you for the expertise.

"Or is Activiti intended to be used with only 1 database schema per server?"

Activiti can be single-tenant, multi tenant with one database or multi tenant with different tenant schema's

"will Activiti remain in memory"

No, Activiti does not keep anything in memory. Only when going from a step A -> B the instance is loaded, changed and persisted again.

"will Activiti keep the database connections open"

No.

Only the job executor will regularly poll the database, but open/close the connections.
