Zeebe maintains a stream to execute a process instance. In this stream, two pointers are running:
* one for the next job to execute (execute a gateway, execute a worker submission)

Where there is a lot of data to process, the Elasticsearch pointer may be late behind the execution:
The stream grows up. This may not be a big deal if, at one moment, the flow slows down, then the second pointer
will catch up. But if this is not the situation, the stream may reach the PVC limit. If this happens, then
the first pointer will slow down, and the Zeebe Engine will stop to accept new jobs: the speed will be then the slowest limit.
