Good introductiory video. Not too many technical details though.
Are compute node SQL Server instances running the same code as the coordinator? Doesn't sound like they need to.
Is data auto partitioning going to be supported?
How Madison compares to now Oracle's Exadata?
What kind of storage (row oriented, column oriented) is used for compute nodes?
Coordinator still seems like a potential bottleneck, if 150 compute nodes start streaming back to the corrdinator, on a poorly scoped query there is still a good chance to food it with data. Are there any provisions for scaling out the coordinator, or it's
vertical scaling for now?
Really looking forward to more videos on Madison (with a bt more details on internals ) .
