Ganesh Vernekar	9199fcb8d1	'@ <timestamp>' modifier (#8121 ) This commit adds `@ <timestamp>` modifier as per this design doc: https://docs.google.com/document/d/1uSbD3T2beM-iX4-Hp7V074bzBRiRNlqUdcWP6JTDQSs/edit. An example query: ``` rate(process_cpu_seconds_total[1m]) and topk(7, rate(process_cpu_seconds_total[1h] @ 1234)) ``` which ranks based on last 1h rate and w.r.t. unix timestamp 1234 but actually plots the 1m rate.

Bartlomiej Plotka	e6d7cc5fa4	tsdb: Added ChunkQueryable implementations to db; unified MergeSeriesSets and vertical to single struct. (#7069 ) * tsdb: Added ChunkQueryable implementations to db; unified compactor, querier and fanout block iterating. Chained to https://github.com/prometheus/prometheus/pull/7059 * NewMerge(Chunk)Querier now takies multiple primaries allowing tsdb DB code to use it. * Added single SeriesEntry / ChunkEntry for all series implementations. * Unified all vertical, and non vertical for compact and querying to single merge series / chunk sets by reusing VerticalSeriesMergeFunc for overlapping algorithm (same logic as before) * Added block (Base/Chunk/)Querier for block querying.

Bartlomiej Plotka	a0df8a383a	promql: Removed global and add ability to have better interval for subqueries if not specified (#7628 ) * promql: Removed global and add ability to have better interval for subqueries if not specified ## Changes * Refactored tests for better hints testing * Added various TODO in places to enhance. * Moved DefaultEvalInterval global to opts with func(rangeMillis int64) int64 function instead Motivation: At Thanos we would love to have better control over the subqueries step/interval. This is important to choose proper resolution. I think having proper step also does not harm for Prometheus and remote read users. Especially on stateless querier we do not know evaluation interval and in fact putting global can be wrong to assume for Prometheus even. I think ideally we could try to have at least 3 samples within the range, the same way Prometheus UI and Grafana assumes. Anyway this interfaces allows to decide on promQL user basis. Open question: Is taking parent interval a smart move? Motivation for removing global: I spent 1h fighting with: === RUN TestEvaluations TestEvaluations: promql_test.go:31: unexpected error: error evaluating query "absent_over_time(rate(nonexistant[5m])[5m:])" (line 687): unexpected error: runtime error: integer divide by zero --- FAIL: TestEvaluations (0.32s) FAIL At the end I found that this fails on most of the versions including this master if you run this test alone. If run together with many other tests it passes. This is due to SetDefaultEvaluationInterval(1 * time.Minute) in test that is ran before TestEvaluations. Thanks to globals (: Let's fix it by dropping this global. Signed-off-by: Bartlomiej Plotka <bwplotka@gmail.com> * Added issue links for TODOs.

Bartlomiej Plotka	fe802f29c9	storage: Removed SelectSorted method; Simplified interface; Added requirement for remote read to sort response. This is technically BREAKING CHANGE, but it was like this from the beginning: I just notice that we rely in Prometheus on remote read being sorted. This is because we use selected data from remote reads in MergeSeriesSet which rely on sorting. I found during work on https://github.com/prometheus/prometheus/pull/5882 that we do so many repetitions because of this, for not good reason. I think I found a good balance between convenience and readability with just one method. Smaller the interface = better. Also I don't know what TestSelectSorted was testing, but now it's testing sorting. Signed-off-by: Bartlomiej Plotka <bwplotka@gmail.com>	5 years ago

Julien Pivotto	9adad8ad30	Remove MaxConcurrent from the PromQL engine opts (#6712 ) Since we use ActiveQueryTracker to check for concurrency in `d992c36b3a` it does not make sense to keep the MaxConcurrent value as an option of the PromQL engine. This pull request removes it from the PromQL engine options, sets the max concurrent metric to -1 if there is no active query tracker, and use the value of the active query tracker otherwise. It removes dead code and also will inform people who import the promql package that we made that change, as it breaks the EngineOpts struct.

Brian Brazil	61262159c4	Simplify benchmark given the new API Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	5 years ago
Brian Brazil	38d32e0686	Don't sort postings if we only have one block. Sorting the heads postings can be quite slow. We only need sorted series when merging with another querier, so only sort then. This will make big queries that only touch the head faster, though queries that touch both the head and a block will still be the same speed. This probably won't help much with graphing unless the range is under an hour, however it should make most recording rules faster. Add gaurantee that remote read streaming produces sorted series. PromQL benchmarks for histograms show only 2-3% improvement, but they're only over 1k series. benchmark old ns/op new ns/op delta BenchmarkQuerierSelect/Head/1of1000000-4 1375486282 507657736 -63.09% BenchmarkQuerierSelect/Head/10of1000000-4 1387859004 507769850 -63.41% BenchmarkQuerierSelect/Head/100of1000000-4 1387087935 506029110 -63.52% BenchmarkQuerierSelect/Head/1000of1000000-4 1386869064 504521986 -63.62% BenchmarkQuerierSelect/Head/10000of1000000-4 1386213685 505210422 -63.55% BenchmarkQuerierSelect/Head/100000of1000000-4 1392754988 529842406 -61.96% BenchmarkQuerierSelect/Head/1000000of1000000-4 1569414722 725059506 -53.80% BenchmarkQuerierSelect/SortedHead/1of1000000-4 1381019902 1370495863 -0.76% BenchmarkQuerierSelect/SortedHead/10of1000000-4 1375696209 1366789468 -0.65% BenchmarkQuerierSelect/SortedHead/100of1000000-4 1386009422 1364519297 -1.55% BenchmarkQuerierSelect/SortedHead/1000of1000000-4 1377700532 1364486191 -0.96% BenchmarkQuerierSelect/SortedHead/10000of1000000-4 1383539536 1369545314 -1.01% BenchmarkQuerierSelect/SortedHead/100000of1000000-4 1410089163 1394731339 -1.09% BenchmarkQuerierSelect/SortedHead/1000000of1000000-4 1634744148 1581554956 -3.25% BenchmarkQuerierSelect/Block/1of1000000-4 881741242 879839470 -0.22% BenchmarkQuerierSelect/Block/10of1000000-4 880381562 882846038 +0.28% BenchmarkQuerierSelect/Block/100of1000000-4 887519357 881016916 -0.73% BenchmarkQuerierSelect/Block/1000of1000000-4 902194205 883433524 -2.08% BenchmarkQuerierSelect/Block/10000of1000000-4 892321964 885130170 -0.81% BenchmarkQuerierSelect/Block/100000of1000000-4 938604466 933527150 -0.54% BenchmarkQuerierSelect/Block/1000000of1000000-4 1313510845 1295881124 -1.34% benchmark old allocs new allocs delta BenchmarkQuerierSelect/Head/1of1000000-4 4000056 4000018 -0.00% BenchmarkQuerierSelect/Head/10of1000000-4 4000074 4000036 -0.00% BenchmarkQuerierSelect/Head/100of1000000-4 4000254 4000216 -0.00% BenchmarkQuerierSelect/Head/1000of1000000-4 4002054 4002016 -0.00% BenchmarkQuerierSelect/Head/10000of1000000-4 4020054 4020016 -0.00% BenchmarkQuerierSelect/Head/100000of1000000-4 4200054 4200016 -0.00% BenchmarkQuerierSelect/Head/1000000of1000000-4 6000054 6000016 -0.00% BenchmarkQuerierSelect/SortedHead/1of1000000-4 4000071 4000071 +0.00% BenchmarkQuerierSelect/SortedHead/10of1000000-4 4000089 4000089 +0.00% BenchmarkQuerierSelect/SortedHead/100of1000000-4 4000269 4000269 +0.00% BenchmarkQuerierSelect/SortedHead/1000of1000000-4 4002069 4002069 +0.00% BenchmarkQuerierSelect/SortedHead/10000of1000000-4 4020069 4020069 +0.00% BenchmarkQuerierSelect/SortedHead/100000of1000000-4 4200069 4200069 +0.00% BenchmarkQuerierSelect/SortedHead/1000000of1000000-4 6000069 6000069 +0.00% BenchmarkQuerierSelect/Block/1of1000000-4 6000023 6000022 -0.00% BenchmarkQuerierSelect/Block/10of1000000-4 6000059 6000058 -0.00% BenchmarkQuerierSelect/Block/100of1000000-4 6000419 6000418 -0.00% BenchmarkQuerierSelect/Block/1000of1000000-4 6004019 6004018 -0.00% BenchmarkQuerierSelect/Block/10000of1000000-4 6040019 6040018 -0.00% BenchmarkQuerierSelect/Block/100000of1000000-4 6400019 6400018 -0.00% BenchmarkQuerierSelect/Block/1000000of1000000-4 10000020 10000019 -0.00% benchmark old bytes new bytes delta BenchmarkQuerierSelect/Head/1of1000000-4 229192200 176001176 -23.21% BenchmarkQuerierSelect/Head/10of1000000-4 229193352 176002328 -23.21% BenchmarkQuerierSelect/Head/100of1000000-4 229204872 176013848 -23.21% BenchmarkQuerierSelect/Head/1000of1000000-4 229320072 176129048 -23.20% BenchmarkQuerierSelect/Head/10000of1000000-4 230472072 177281048 -23.08% BenchmarkQuerierSelect/Head/100000of1000000-4 241992072 188801048 -21.98% BenchmarkQuerierSelect/Head/1000000of1000000-4 357192072 304001048 -14.89% BenchmarkQuerierSelect/SortedHead/1of1000000-4 229193928 229193928 +0.00% BenchmarkQuerierSelect/SortedHead/10of1000000-4 229195080 229195080 +0.00% BenchmarkQuerierSelect/SortedHead/100of1000000-4 229206600 229206600 +0.00% BenchmarkQuerierSelect/SortedHead/1000of1000000-4 229321800 229321800 +0.00% BenchmarkQuerierSelect/SortedHead/10000of1000000-4 230473800 230473800 +0.00% BenchmarkQuerierSelect/SortedHead/100000of1000000-4 241993800 241993800 +0.00% BenchmarkQuerierSelect/SortedHead/1000000of1000000-4 357193800 357193800 +0.00% BenchmarkQuerierSelect/Block/1of1000000-4 227201516 227201500 -0.00% BenchmarkQuerierSelect/Block/10of1000000-4 227202924 227202908 -0.00% BenchmarkQuerierSelect/Block/100of1000000-4 227217036 227217020 -0.00% BenchmarkQuerierSelect/Block/1000of1000000-4 227358156 227358140 -0.00% BenchmarkQuerierSelect/Block/10000of1000000-4 228769356 228769340 -0.00% BenchmarkQuerierSelect/Block/100000of1000000-4 242881356 242881340 -0.00% BenchmarkQuerierSelect/Block/1000000of1000000-4 384001616 384001600 -0.00% Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	5 years ago
