## What changes were proposed in this pull request? In `SQLAppStatusListener.aggregateMetrics`, we use the `metricIds` only to filter the relevant metrics. And this is a Seq which is also sorted. When there are many metrics involved, this can be pretty inefficient. The PR proposes to use a Set for it. ## How was this patch tested? NA Closes apache#23002 from mgaido91/SPARK-26003.
