What this PR does
Upgrade to latest mimir-prometheus: de14b0ea393d.
Significant Prometheus changes
The main changes are OTLP related, i.e. that Prometheus now has taken ownership of its
otlptranslator
package (forked it from opentelemetry-collector-contrib), and that the OTel->Prometheus remote write format translation is now optimized through hash based metric identifiers (instead of string based ones). Prometheus benchmarks show huge performance improvements from the latter.Benchmarks
The
OTLPHandler
benchmarks don't show any enormous improvements, but it's possible that this is due to having to convert from Prometheus remote write format to Mimir's. It's also possible that our benchmark suite doesn't quite cover all of the improved cases versus the benchmark suite in Prometheus.Benchmark stats vs main branch
