Oleg Zaytsev	9699598952	Improve Labels.Compare performance w/stringlabels I was bored on a train and I spent some amount of time trying to scratch some nanoseconds off the Labels.Compare when running with stringlabels. I would be ashamed to admit the real amount of time I spent on it. The worst thing is, I can't really explain why this is performing so much better, and someone should re-run the benchmarks on their machine to confirm that it's not something related to general relativity because the train is moving. I also added some extra real-life benchmark cases with longer labelsets (these aren't the longest we have in production, but kubernetes labelsets are fairly common in Prometheus so I thought it would be nice to have them). My benchmarks show this diff: goos: darwin goarch: arm64 pkg: github.com/prometheus/prometheus/model/labels │ old │ new │ │ sec/op │ sec/op vs base │ Labels_Compare/equal 5.898n ± 0% 5.875n ± 1% -0.40% (p=0.037 n=10) Labels_Compare/not_equal 11.78n ± 2% 11.01n ± 1% -6.54% (p=0.000 n=10) Labels_Compare/different_sizes 4.959n ± 1% 4.906n ± 2% -1.05% (p=0.050 n=10) Labels_Compare/lots 21.32n ± 0% 17.54n ± 5% -17.75% (p=0.000 n=10) Labels_Compare/real_long_equal 15.06n ± 1% 14.92n ± 0% -0.93% (p=0.000 n=10) Labels_Compare/real_long_different_end 25.20n ± 0% 24.43n ± 0% -3.04% (p=0.000 n=10) geomean 11.86n 11.25n -5.16% Signed-off-by: Oleg Zaytsev <mail@olegzaytsev.com>	8 months ago

Ondrej Kokes	2e30f1231b	docs: textparse.Parser return type mismatch The docs suggest the Next method returns a bool, but that's not the case (`Entry` is an int). ``` // Next advances the parser to the next sample. It returns false if no // more samples were read or an error occurred. Next() (Entry, error) ``` The docs were first added in `d80a3de235` in 2017. Back then the signature was indeed `func (p *Parser) Next() bool`. But then it got refactored in `76a4a46cb0` and the signature changed with it, yet docs stayed the same - and eventually made their way into the `Parser` interface. However, the Protobuf parser does have the right wording: `5de2df752f` ``` // Next advances the parser to the next "sample" (emulating the behavior of a // text format parser). It returns (EntryInvalid, io.EOF) if no samples were // read. ``` Changing all other implementations (and the interface itself) to match this doc.

Łukasz Mierzwa	5597020a60	Use github.com/klauspost/compress for gzip and zlib klauspost/compress is a high quality drop-in replacement for common Go compression libraries. Since Prometheus sends out a lot of HTTP requests that often return compressed output having improved compression libraries helps to save cpu & memory resources.

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.

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.

Filip Petkovski	583f3e587c	Optimize histogram iterators (#13340 ) Optimize histogram iterators Histogram iterators allocate new objects in the AtHistogram and AtFloatHistogram methods, which makes calculating rates over long ranges expensive. In #13215 we allowed an existing object to be reused when converting an integer histogram to a float histogram. This commit follows the same idea and allows injecting an existing object in the AtHistogram and AtFloatHistogram methods. When the injected value is nil, iterators allocate new histograms, otherwise they populate and return the injected object. The commit also adds a CopyTo method to Histogram and FloatHistogram which is used in the BufferedIterator to overwrite items in the ring instead of making new copies. Note that a specialized HPoint pool is needed for all of this to work (`matrixSelectorHPool`). --------- Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com> Co-authored-by: George Krajcsovits <krajorama@users.noreply.github.com>	10 months ago

Bryan Boreham	0289dd6157	relabel: blank replacement deletes label post-regexp If `cfg.TargetLabel` is a template like `$1`, it won't match any labels, so no point calling `lb.Del` with it. Similarly if `target` is not a valid label name, it won't match any labels, so don't call with that either.

Filip Petkovski	9008271df5	Use cap to determine slice capacity Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com>	12 months ago
Filip Petkovski	10a82f87fd	Enable reusing memory when converting between histogram types The 'ToFloat' method on integer histograms currently allocates new memory each time it is called. This commit adds an optional *FloatHistogram parameter that can be used to reuse span and bucket slices. It is up to the caller to make sure the input float histogram is not used anymore after the call. Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com>	12 months ago
