Bryan Boreham	6ba25ba93f	tsdb tests: avoid 'defer' till end of function ... 'defer' only runs at the end of the function, so explicitly close the querier after we finish with it. Also check it didn't error. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	11 months ago
Bryan Boreham	2f615a200d	tsdb tests: restrict some 'defer' operations ... 'defer' only runs at the end of the function, so introduce some more functions / move the start, so that 'defer' can run at the end of the logical block. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	11 months ago

Bryan Boreham	cfa32f3d28	TSDB: Move merge of head postings into index ... This enables it to take advantage of a more compact data structure since all postings are known to be `*ListPostings`. Remove the `Get` member which was not used for anything else, and fix up tests. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	1 year ago
Bryan Boreham	0a8779f46d	TSDB: Make mergedPostings generic ... Now we can call it with more specific types which is more efficient than making everything go through the `Postings` interface. Benchmark the concrete type. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	1 year ago
Bryan Boreham	1b22242024	TSDB BenchmarkMerge: run fewer sizes ... As long as we run small and big sizes, we don't need all the sizes inbetween. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	1 year ago
Bryan Boreham	e630ffdbed	TSDB: extend BenchmarkMemPostings_PostingsForLabelMatching to check merge speed ... We need to create more postings entries so the merger has some work to do. Not material for the regexp ones as they match so few series. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	1 year ago

Bryan Boreham	ac4f8a5e23	[ENHANCEMENT] TSDB: Improve calculation of space used by labels (#13880) ... * [ENHANCEMENT] TSDB: Improve calculation of space used by labels The labels for each series in the Head take up some some space in the Postings index, but far more space in the `memSeries` structure. Instead of having the Postings index calculate this overhead, which is a layering violation, have the caller pass in a function to do it. Provide three implementations of this function for the three Labels versions. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	1 year ago

György Krajcsovits	a325ff142c	fix(test): do not run automatic WAL truncate during test ... Remove the 2 minute timeout as the default is 2 hours and wouldn't interfere. With the test.

György Krajcsovits	b94c87bea6	fix(test): TestCheckpoint segment size too low ... The segment size was too low for the additional NHCB data, thus it created more segments then expected. This meant that less were in the lower numbered segments, which meant more was kept.

Oleg Zaytsev	cd1f8ac129	MemPostings: keep a map of label values slices (#15426) ... While investigating lock contention on `MemPostings`, we saw that lots of locking is happening in `LabelValues` and `PostingsForLabelsMatching`, both copying the label values slices while holding the mutex. This adds an extra map that holds an append-only label values slice for each one of the label names. Since the slice is append-only, it can be copied without holding the mutex.

Oleg Zaytsev	9ad93ba8df	Optimize l=~".+" matcher (#15474) ... Since dot is matching newline now, `l=~".+"` is "any non empty label value", and #14144 added a specific method in the index for that so we don't need to run the matcher on each one of the label values.
