feat: add capped sampling rate increases by raphaelgavache · Pull Request #10715 · DataDog/dd-trace-java

raphaelgavache · 2026-03-02T19:15:06Z

When the trace-agent is restarted, a rate of 100% is initially provided by the trace-agent, increasing dramatically the number of traces sampled. A rate could go suddenly from 0.1% to 100% and back to 0.1% when the trace-agent eventually computes the new sampling rate.

In particular it is observed that when the agent restarts, the payload buffering that waits for new container tags breaches its memory limit and we send spans without container tags.

This PR applies a limit of sampling rate increases of x2 every 1s resulting in a x10 completed every 3-4s
1->100% takes 7s
0.1 -> 100% takes 10s
