Enabling optimized map by default #10016

dougqh · 2025-11-21T19:38:25Z

What Does This Do

Enables the "optimized" TagMap by default

Motivation

OptimizedTagMap is special HashMap that is designed to be good at common tracer usage patterns.
OptimizedTagMap uses immutable TagMap.Entry-s

By using immutable TagMap.Entry-s...

Entry-s can be shared between TagMap.Ledger (a builder) and the constructed TagMap
Entry-s can be shared between TagMap instances when performing putAll

TagMap.Entry-s are also capable of storing primitives without boxing

All of these capabilities are intended to minimize the allocation done by the tracer when constructing Span-s

Additional Notes

Follow-up to

Reduce span construction overhead by switching to optimized TagMap #8589

-    this.optimizedMapEnabled =
-        configProvider.getBoolean(GeneralConfig.OPTIMIZED_MAP_ENABLED, false);
+    this.optimizedMapEnabled = configProvider.getBoolean(GeneralConfig.OPTIMIZED_MAP_ENABLED, true);


Just curious, if it is a config change, do we need to update some other place too?
@mhlidd Could you check this PR too?

I think that only applies if we introduce a config variable. This config has been in place for some time now.
