Prometheus
OPEN SOURCE
DESCRIPTION
Prometheus decodes every HTTP round-trip through its official Go client, and it was parsing the same JSON twice — once into an intermediate representation, then again into the target. The work was finding that duplicate parse and taking it out of every method that carried it, without changing what any of them returned.
HIGHLIGHTS
- Removed a redundant JSON parse across 20 methods of the official Prometheus Go client, cutting memory allocation by 10.5% and decode time by 21.3%.
- Merged the change upstream into a repository with over 6,000 stars, carrying it through review by the maintainers who own the code rather than just past its tests.
