Please describe your use case here, what are you trying to achieve e.g. "I want to collect only error traces"
A proposal that from your POV would solve the problem or improve the existing situation e.g. "I want the hypertrace-collector to have a filter for error traces". If you don't have a proposed solution, that's fine too.
Questions that should be answered during the discussion of this issue before jumping into code. Also beneficial to test asumptions e.g. "Confirm that you support custom builds for collector".
