Track perf events for only the high-priority (PR) tasks.

Allow setting retention per metric (e.g rule aggregation)

59

In ideal world retention is not necessary on downsampling/raw leve, but on aggregation level. We need to have the way to bring it through in LTS system like Thanos. AC:...

compact: Ensure downsampled chunks are not larger than 120 samples; stream downsampling more

Let's start with **acceptance criteria** for our compatibity tests: * I would like to know with which versions of Prometheus Thanos *supports* on *each* PR. But what we mean by...

s3/aliyunOSS: Support multipart upload without pre known object size.

We could make test cleanup more reliable following a similar pattern as in https://golang.testcontainers.org/features/garbage_collector/ Perhaps one container that deletes the whole network? (no need for sidecars). What would be enough...

Using goleak on Go benchmarks.

It would be amazing to have goleak working on Benchmarks as well. However, I think some functions might needed to be filtered by default. Repro: ``` func BenchmarkGoroutines(b *testing.B) {...

Otherwise HTTP library might not be able to reuse TCP connections. Signed-off-by: bwplotka

Allow Prometheus to use ReadRequest_STREAMED_XOR_CHUNKS when calling remote read API.

https://github.com/prometheus/prometheus/pull/5703 extended remote read protocol and added `ReadRequest_STREAMED_XOR_CHUNKS` Prometheus implements remote read API, but it can also be configured to **use/call** other remote read API. Enable streaming remote read if...
