Store accumulator-stage lookups directly by charlesmyu · Pull Request #10645 · DataDog/dd-trace-java

charlesmyu · 2026-02-19T21:51:36Z

What Does This Do

Stores the map of accumulator ID to stage ID directly in a Long - Integer map, rather than storing the stage-level accumulators themselves.

Motivation

The stage-level accumulators naively roll up metrics from the task level by summing all values. This means they are not accurate in all cases, particular for metrics that are better visualized as a distribution of values across all tasks instead of a single sum.

In #10553 we rollup task-level metrics ourselves and encode them into the Spark SQL metrics as distributions in order to improve the granularity of information collected. This left one remaining use of the stage-level accumulators - mapping operations in Spark SQL plans to their respective stages.

Since we do not need the entire accumulator to accomplish this, we should simplify that to a ID-ID map instead to save space. We can also remove the 50k limit since we are not storing the entire accumulator, allowing us to avoid creating orphaned operations (previously occurred when the EldestHashMap overflowed).

Additional Notes

I didn't feel the explicit need for a FF here, since the change is fairly straightforwards and shouldn't negatively impact perf. However, if we feel strongly otherwise I'm happy to make that happen.
