Bryan Boreham	b9fdf3dad1	storage/remote: document why two benchmarks are skipped One was silently doing nothing; one was doing something but the work didn't go up linearly with iteration count. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	10 months ago

Bryan Boreham	14b4fbc2ff	labels: make InternStrings a no-op for stringlabels version The current implementation of `InternStrings` will only save memory when the whole set of labels is identical to one already seen, and this cannot happen in the one place it is called from in Prometheus, remote-write, which already detects identical series.

Bryan Boreham	dcd024a095	storage/remote: speed up StoreSeries by re-using labels.Builder Relabeling can take a pre-populated `Builder` instead of making a new one every time. This is much more efficient. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	10 months ago

Marco Pracucci	501bc6419e	Add ShardedPostings() support to TSDB (#10421 ) This PR is a reference implementation of the proposal described in #10420. In addition to what described in #10420, in this PR I've introduced labels.StableHash(). The idea is to offer an hashing function which doesn't change over time, and that's used by query sharding in order to get a stable behaviour over time. The implementation of labels.StableHash() is the hashing function used by Prometheus before stringlabels, and what's used by Grafana Mimir for query sharding (because built before stringlabels was a thing). Follow up work As mentioned in #10420, if this PR is accepted I'm also open to upload another foundamental piece used by Grafana Mimir query sharding to accelerate the query execution: an optional, configurable and fast in-memory cache for the series hashes.

Filip Petkovski	a577a0a542	Fix last_over_time for native histograms The last_over_time retains a histogram sample without making a copy. This sample is now coming from the buffered iterator used for windowing functions, and can be reused for reading subsequent samples as the iterator progresses. I would propose copying the sample in the last_over_time function, similar to how it is done for rate, sum_over_time and others.

Bryan Boreham	66237c1996	tsdb: use cheaper Mutex on series Mutex is 8 bytes; RWMutex is 24 bytes and much more complicated. Since `RLock` is only used in two places, `UpdateMetadata` and `Delete`, neither of which are hotspots, we should use the cheaper one. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	10 months ago

beorn7	fe35f2dac3	Name @beorn7 and @krajorama as maintainers for native histograms I have been the de-facto maintainer for native histograms from the beginning. So let's put this into MAINTAINERS.md. In addition, I hereby proposose George Krajcsovits AKA Krajo as a co-maintainer. He has contributed a lot of native histogram code, but more importantly, he has contributed substantially to reviewing other contributors' native histogram code, up to a point where I was merely rubberstamping the PRs he had already reviewed. I'm confident that he is ready to to be granted commit rights as outlined in the "Maintainers" section of the governance: https://prometheus.io/governance/#maintainers According to the same section of the governance, I will announce the proposed change on the developers mailing list and will give some time for lazy consensus before merging this PR.

Bryan Boreham	b9eab6e4b8	tsdb: simplify internal series delete function (#13261 ) Lifting an optimisation from Agent code, `seriesHashmap.del` can use the unique series reference, doesn't need to check Labels. Also streamline the logic for deleting from `unique` and `conflicts` maps, and add some comments to help the next person. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	10 months ago
Bryan Boreham	74b73d1e2c	Labels: Add DropMetricName function, used in PromQL (#13446 ) This function is called very frequently when executing PromQL functions, and we can do it much more efficiently inside Labels. In the common case that `__name__` comes first in the labels, we simply re-point to start at the next label, which is nearly free. `DropMetricName` is now so cheap I removed the cache - benchmarks show everything still goes faster.
