The C3PO daemon is responsible for dynamic data placement.
optional arguments:
-h, --help show this help message and exit
--run-once One iteration only
--threads THREADS Concurrency control: number of threads
--only-workload Only run the workload collector
--dry_run DRY_RUN, --dry-run DRY_RUN
Do not create any rules
--sampling In the end flip a to decide to create a rule or not
--algorithms ALGORITHMS
