Hi @sakuraime ,

This is the official doc: https://learn.microsoft.com/en-us/sql/relational-databases/polybase/polybase-scale-out-groups?view=sql-server-ver15

so what's the max number of computing nodes . ?

At present, Microsoft has not given an answer to this question. I will update the process if there is any follow-up.

any the headnode can also have max 8 readers against the partitioned table ?

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.

Best regards,
Seeya
