The runtime profile as we present it is not very useful and I think the structure of it makes it hard to consume. This patch adds a new client facing schemed set of counters that are collected from the runtime profiles. For example, with this structure it would be easy to have the shell get the stats of a running query and print a useful progress report or to check the most relevant metrics for diagnosing issues. Here's an example of the output for one of the tpch queries: Operator #Hosts Avg Time Max Time #Rows Est. #Rows Peak Mem Est.
