Chetan, It appears that I can at least trigger the async indexing from within my application. That leaves me with two questions that I hope you can find time to answer:
1. Is there an optimal frequency for indexing that you would recommend? 2. Why doesn’t the checkpoints prevent resource contention? It would appear to me that they should.
