Visit http://localhost:8080/modwf/engine/default/process-definition http://localhost:8080/modwf/process-instance/count after deploy

What needs to be done

Modify ProcessEngineProducer as in the multi-tenancy/schema-isolation project above to inject tenant-specific engines into incoming web requests

Programatically create tenants as per https://forum.camunda.org/t/multi-tenancy-programmatically-create-tenant/2876/5

THe demo

Make sure you've got a postgres db

have a hostname pghost for easy aliasing of postgres server. The JDBC connection is set for this host, just alias localhost to run locally.

psql -U postgres -h localhost 

// DROP DATABASE foliodev;
CREATE DATABASE foliodev;
CREATE USER folio WITH PASSWORD 'folio';
GRANT ALL PRIVILEGES ON DATABASE foliodev to folio;

As folio user

psql -U folio -h localhost 
create schema camunda_default;
create schema modwf_diku;
