Minimal resource allocation
Because the process engine is stateless, it allocates a minimal amount of RAM resource per node (typically less than 10 MB). Basically, you can have billions of process instances persisted in the database, without a necessary impact on resource allocation per node. This also means that you can run many process engine instances per node.
