(Glue-2105) Q: How much effort is needed to implement the solution?

The time to implement depends on the data scope and the system landscape. Assuming agile development processes, the first results of data replication and data flows can be achieved within hours/days. To give you some insights into a simple scenario, where the goal was to set up a Spend Analysis reporting dashboard on an external database with PowerBI as UI frontend: the identification of the approximately 20 tables, along with the initial setup of the data flows was done in one afternoon (including an initial load of data, which included 250k purchase orders). For large-scale implementations, the time for setting up the connectivity, implementing a data model & data flows, and perform initial heavy lifting will, of course, be much longer.
