[jira] [Commented] (IMPALA-7166) ExecSummary should be a first
class object
[ https://issues.apache.org/jira/browse/IMPALA-7166?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16609447#comment-16609447 ]
Tim Armstrong commented on IMPALA-7166:
---------------------------------------
Here's the RuntimeProfile thrift structure: https://github.com/apache/impala/blob/master/common/thrift/RuntimeProfile.thrift#L100
We already have a thrift representation of the exec summary here: https://github.com/apache/impala/blob/master/common/thrift/ExecStats.thrift#L82
I think we probably want to include the TExecSummary in the top-level TRuntimeProfile object.
Note that if we want to change the representation of TExecSummary, this is our chance because we're now exposing it as more of a public interface.
Here's a simple utility that dumps thrift profiles:
https://github.com/apache/impala/blob/64e6719870db5602a6fa85014bc6c264080b9414/bin/parse-thrift-profile.py
Note existing tools expect the ExecSummary to be present as a string in the profile, and it is often very useful for people debugging queries using the text profile, so we should avoid removing the existing string version

> Impala RuntimeProfile currently contains "ExecSummary" as a string. We should make it a first class thrift object, so that tools can extract these fields (Est rows etc..),
