When DIH Round Robin mode indexing is enabled, use the [DAHServer<N>] options to configure child engines for power up and shut down when roll-over occurs. This allows optimal data indexing on a specific child engine by suspending query handling on that engine.
For example, if RoundRobinMode=true:
When a roll over occurs, the DAH child engine that indexed data yesterday and the DAH child engine that indexes data today will shut down. At the same time, the DAH child engine that indexed data the day before yesterday will be powered up.
