I think we could just add a PinotProperty that defines the max dataTable size and set that to something like 100-500 by default. With that single change, we could avoid all these issues. That may be problematic in cases where a query requires a very large request from a server, but that is not a normal kind of queries in a OLAP system and it could be changed at startup time if needed -- This is an automated message from the Apache Git Service.
