DSM optimizations - major refactoring to get rid of LinkedHashMap #9151

kr-igor · 2025-07-10T20:25:56Z

This change is aimed to reduce DSM overhead by using a lightweight object instead of linked maps.

Introduced DataStreamsTags which are now used instead of LinkedHashMap.
Updated all integrations and tests.

My tests show ~20% throughput increase with a significant latency decrease without increasing CPU load. (left side is v1.51.1, right side is this branch)

I would avoid builder idioms in the critical path. That's still extra allocation that we really don't need.

This is introducing a capturing lambda. I think a regular loop would probably be better here.

I think this code will produce String with TWO commas. Is that expected?

Yes, you are right... AI autosuggest :D

I think we can probably still keep these pretty clean without needing a builder. I've put suggestions throughout...

If you're in refactoring mode, can you have a look (made in another PR if it's easier) to complete the context refactoring?

In short, PathwayContext should not be stored in span data model (DDSpanContext).
Instead, it must be stored with Context as DataStreamsContext and AgentSpan.
You may create a second Context entry if the DataStreamsContext holds different kind of data (or have a different lifecycle) than what PathwayContext should hold.

I already done some refactoring (adding DataStreamsContext, creating a dedicated DSM propagator) but it miss the last step of moving away PathwayContext from span.
Would that be something you could have a look at? Would you like us to pair on this task? The end goal would be to decouple Tracing from DSM. So you can save even more resources.

+      DataStreamsTags tags =
+          DataStreamsTags.createWithBus("bus", DataStreamsTags.Direction.Outbound, eventBusName);


Why pass "bus" as argument to withBus helper? Is there a case where the value isn't "bus"?

Yes, the type is always bus, no need to pass it here.

That's a very nice improvement. Looks good to me.
