sorry for delay in response, generally it was taken care by hosting provider, they migrated database to other server and issues gone, not sure really what they did, thank you all for effort ! — user130071May 18 '18 at 11:23
Morning Heapsters. I'm working with Azure Synapse. I'd like to learn more about the distributed part of query optimisation there - DSQL they call it. Does anyone have a link they can share about how the internals work? I've searched Google, naturally; was wondering if you knew of conference papers or journal articles and the like. Thanks all.
