> SQL Rest API exposes query execution metrics as Public API. This Jira aims to
> apply following improvements on SQL Rest API by aligning Spark-UI.
> *Proposed Improvements:*
> 1- Support Physical Operations and group metrics per physical operation by
> aligning Spark UI.
> 2- Support *wholeStageCodegenId* for Physical Operations
> 3- *nodeId* can be useful for grouping metrics and sorting physical
> operations (according to execution order) to differentiate same operators (if
> used multiple times during the same query execution) and their metrics.
> 4- Filter *empty* metrics by aligning with Spark UI - SQL Tab. Currently,
> Spark UI does not show empty metrics.
> 5- Remove line breakers(*\n*) from *metricValue*.
> 6- *planDescription* can be *optional* Http parameter to avoid network cost
> where there is specially complex jobs creating big-plans.
> 7- *metrics* attribute needs to be exposed at the bottom order as
> *metricDetails*. Specially, this can be useful for the user where
> *metricDetails* array size is high.
> 8- Reverse order on *metricDetails* aims to match with Spark UI by supporting
> Physical Operators' execution order.
> *Attachments:*
> Please find both *current* and *improved* versions of the results as
> attached for following SQL Rest Endpoint:
> {code:java}
> curl -X GET
> http://localhost:4040/api/v1/applications/$appId/sql/$executionId?details=true{code}
