what's the Polybase scale-out maximum number of compute node?
I know each compute node has max 8 readers.
At present, Microsoft has not given an answer to this question. I will update the process if there is any follow-up.
so what's the max number of computing nodes . ?
Yes. Each node in a PolyBase scale-out group can spin up to 8 readers to read external data. And each reader is assigned one partition to read in the external table.
any the headnode can also have max 8 readers against the partitioned table ?
