György Krajcsovits	1cdc956d27	test(rw2): add nhcb testcases to remote write 2.0 Ref: https://github.com/prometheus/prometheus/issues/15021 Also modified spansToSpansProto to not allocate empty bucket spans array when converting internal model to remote write model. Otherwise the test TestDecodeWriteV2Request fails since empty array is marshaled/unmarshaled as nil so we don't get back the exact same thing.

Oleg Zaytsev	c5b92f71d4	fix: storage/remote.pool interned refs count and flaky test (#16335 ) * Fix storage/remote.pool interned refs count and flaky test I saw TestIntern_MultiRef_Concurrent failing on a different PR saying 'expected refs to be 1 but it was 2'. I took a look, and it definitely can be racy, especially with a time.Sleep() of just 1ms. I'm fixing that by explicitly waiting until it has been released, and by repeating that 1000 times, otherwise it's just a recipe for a future flaky test. OTOH, I also took a look at the implementation and saw that we were not holding the RLock() when increasing the references count, so when releasing there was a race condition for the cleanup, I fixed that by holding RLock() while increasing the references count.

sh0rez	5303e515af	remote/otlp: convert delta to cumulative (#15165 ) What Adds support for OTLP delta temporality to the OTLP endpoint. This is done by calling the deltatocumulative processor from the OpenTelemetry collector during OTLP conversion. Why Delta conversion is a naturally stateful process, which requires careful request routing when operated inside a collector. Prometheus is already stateful and doing the conversion in-server reduces the operational burden on the ingest architecture by only having one stateful component. How deltatocumulative is a OTel collector component that works as follows: * pmetric.Metrics come from a receiver or in this case from the HTTP client * It operates as an in-place update loop: * for each sample, if not delta, leave unmodified * if delta, do: * state += sample, where state is the in-memory sum of all previous samples * sample = state, sample value is now cumulative * this is supported for sums (counters), gauges, histograms (old histograms) and exponential histograms (native histograms) If a series receives no new samples for 5m, its state is removed from memory Performance Delta performance is a stateful operation and the OTel code is not highly optimized yet, e.g. it locks the entire processor for each request. Nonetheless, care has been taken to mitigate those effects: delta conversion is behind a feature flag. If disabled, no conversion code is ever invoked if enabled, conversion is not invoked if request not actually contains delta samples. This leads to no measureable performance difference between default-cumulative to convert-cumulative (only cumulative, feature on/off) Signed-off-by: sh0rez <me@shorez.de>	1 year ago
