Bryan Boreham	eff3a13e19	model/textparse: parsers take a labels SymbolTable This allows strings to be interned to save memory. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
Bryan Boreham	123109e967	config: make work with SymbolTable labels Need a SymbolTable when we expand ExternalLabels. And we can't use labels.NewBuilder because we need to add blank values. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
Bryan Boreham	3716326f3f	rules: call NewScratchBuilder Need to initialize ScratchBuilder with a SymbolTable. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago

Bryan Boreham	93b72ec5dd	tsdb: create SymbolTables for labels as required Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
Bryan Boreham	2ac1632eec	storage/remote: improve symbol-table handling On the incoming path, `writeHandler.write()` creates a new table for each request. `labelProtosToLabels` takes a `ScratchBuilder` now. Call `NewScratchBuilder` as required in tests. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago

Bryan Boreham	b39286fd1f	Add dedupelabels tag to not build regular labels Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago
Bryan Boreham	d51a5344cd	labels: new version de-duplicating strings in SymbolTables The individual strings for label names and values are held in a table, and each Labels value is a run of varint-encoded indexes into that table. When creating new labels, a sync.Mutex is locked around reads and writes. When reading labels, there is no locking because the table of strings used by those labels is immutable.

Bryan Boreham	28191109a8	Labels: add fake versions of SymbolTable apis So we can use them where necessary for internlabels implementation. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago

Łukasz Mierzwa	daeef6ffc3	Add lint checks for gzip/zlib Since we want to use a faster gzip/zlib libraries we should add a lint check so that it's used everywhere Signed-off-by: Łukasz Mierzwa <l.mierzwa@gmail.com>	2 years ago
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. On a test Prometheus server I was able to see cpu reduction from 31 to 30 cores.

Bryan Boreham	6ed56c9f04	WAL watcher: improve comments Clarify in the first comment that it is `watch()` that waits, and reduce verbiage. The second comment was slightly contradictory to the first and otherwise didn't seem to add much, since `currentSegment` was incremented just a few lines later.

Owen Williams	a28d7865ad	UTF-8: Add support for parsing UTF8 metric and label names This adds support for the new grammar of `{"metric_name", "l1"="val"}` to promql and some of the exposition formats. This grammar will also be valid for non-UTF-8 names. UTF-8 names will not be considered valid unless model.NameValidationScheme is changed.
