fix: Various metrics bug fixes and improvements #1111
Conversation
@viirya @parthchandra @mbutrovich This is still WIP but let me know what you think of the overall approach here if you have time. Current status is that we now log the metrics that we are dropping. Here are two examples from TPC-H q3. We wrap an aggregate in a projection causing:
The input to a SortExec is a ScanExec to fetch the input batches from the JVM, and we drop those metrics:

Arc::new(SparkPlan::new_with_additional( | ||
spark_plan.plan_id, | ||
projection, | ||
vec![child], | ||
vec![aggregate], | ||
)), |

This is an example where we are currently dropping the aggregate metrics and just capturing the projection metrics
My initial thoughts:
|
Approach looks good (though I cannot say I understand it completely). The results are definitely what we wanted! |
I can possibly break this down into some smaller PRs as well. I may do that. |

is it dropped because it repeats what we have on SparkPlan?

perhaps jvm_fetch_time
enough for now, but if you wanna expand metrics in future its better to have a wrapper structure similar to BaselineMetrics
?

It was not being used yet, but I have now pushed a commit to include it in the "native explain" output, to make it easier to debug performance issues

Probably as you do use the plan_id we should document how it is used.

Thanks for the reviews @parthchandra and @comphead. I am going to go ahead and merge but will be following up with some more changes since I just learned more and will need to refine these metrics to make them more useful. |

Rationale for this change
We currently drop some native metrics due to a design flaw in the current metrics code where we assume that the native plan is a 1:1 mapping with the Spark plan, which is often not true. See the issue for more details.
Improvement 1: Fix bug where metrics were being dropped in some cases
Here are before and after images for
BulidRight
hash join where we insert an extra projection on the native side, breaking the assumption that there is a 1:1 mapping between Spark plan and native plan:Improvement 2: Report Arrow FFI time for passing batches from JVM to native
We now include the
ScanExec
time for transferring batches from JVM to native. The following example shows total scan time of 16.4 seconds but now also shows the additional 17.7 seconds for transferring those batches to native for the filter operation.What changes are included in this PR?
The native planner now builds a tree of
SparkPlan
that is a 1:1 mapping with the original Spark plan. EachSparkPlan
can reference multiple native plans that should be used for metrics collection.How are these changes tested?
Existing tests, and new unit tests in the planner
