Re: Model Lifecycle. This might help...
We have customised the QueryEngineWorker to provide what we call a journal. The journal intercepts all updates and makes entries into a separate dataset. This allows us to provide point in time reasoning across the original data. Ie what was the o for a given s and p over a time period. Also allows us to ship to another data store for load balancing and resiliency.
