Using transactions for chunk migrations is a very lucrative idea because it gets rid of orphaned documents. However, there is concern that it will not be able to match the speed of regular chunk migration and/or that it would be the cause of a too frequent refreshes.
This ticket is an attempt to implement chunk migration using distributed transactions and to evaluate the feasibility of such as solution.
