chore: refactor tracer partial flushing logic #14860

brettlangdon · 2025-10-14T14:23:00Z

Description

This simplify the code and removes the edge case where we tag a complete trace chunk with unnecessary partial flush tag

We move some of the complexity of removing finished spans from a trace into a method.

We add slots to _Trace object to aid in memory usage and size.

Small performance win to use span.duration_is is not None to check if a span if finished instead of using the finished property function.

Seems like this might be a bugfix since it changes some snapshots

Seems like this might be a bugfix since it changes some snapshots

I don't think so, since it is an internal only tag that is only used for debugging. Customer behavior changes should be nothing.

The main change to the snapshot files is, we no longer tag root spans as being partial flushed.

e.g. if we have partial flush count set to 1 and have:

- root
  -  child

When child finishes we'll trigger a partial flush since >= 1 spans are finished, so we tag that trace chunk that it is a partial flush.

When root finishes previously we would also tag it as a partial flush because >= 1 spans are finished.

With this change, we do not set the tag if finished spans count == total trace spans count.

So the snapshot files are just updating the places where we were setting the partial flush tag on complete/finished trace chunks flushing.
