Cyril Tovena	5070605335	Fixes absent_over_time to work with all log selector. (#3143) ... * Fixes absent_over_time to work with all log selector. I made a mistake forcing absent_over_time to work only for unwrap, which is not the most useful usecase. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * actually add a test that cover the previous mistake :) Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com>	5 years ago

Cyril Tovena	c971e8e65a	Optimizes SampleExpr to remove unnecessary line_format. (#3065) ... * Optimizes SampleExpr to remove unnessary line_format. When doing count_over_time and rate(), it doesn't make sense to have a line_format since you're counting line, you don't really care about what the line contains. At the same time this set the foundation of for further optimization, like parsing only required labels during label parsing. I've also found a bug where `topk by(foo) (1...` where not correctly parsed. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * For all range vector operations.

Cyril Tovena	7682f133b6	Improve JSON parser and add labels parser hints. (#3080) ... * Improve JSON parser and add labels parser hints. This is a rework of the json parser, that now uses iteration over reflection allowing to avoid allocations. I've also implemented a way to guess and hints what labels needs to be parsed when doing metric queries, this means we can extract only the few labels required from the log line. benchcmp ``` ❯ benchcmp before.txt after.txt5 benchmark old ns/op new ns/op delta Benchmark_Parser/json/no_labels_hints-16 9889 3281 -66.82% Benchmark_Parser/logfmt/no_labels_hints-16 1624 1671 +2.89% Benchmark_Parser/logfmt/labels_hints-16 1601 790 -50.66% benchmark old allocs new allocs delta Benchmark_Parser/json/no_labels_hints-16 139 56 -59.71% Benchmark_Parser/logfmt/no_labels_hints-16 31 31 +0.00% Benchmark_Parser/logfmt/labels_hints-16 31 5 -83.87% benchmark old bytes new bytes delta Benchmark_Parser/json/no_labels_hints-16 3671 912 -75.16% Benchmark_Parser/logfmt/no_labels_hints-16 464 464 +0.00% Benchmark_Parser/logfmt/labels_hints-16 464 144 -68.97% ``` I've experienced a 2x to 4x improvement in my cluster.

Cyril Tovena	6d85c7c212	Add absent_over_time (#3053) ... * Add absent_over_time This adds absent_over_time which is super useful when alerting, it can be combine with any logql selector including parsers and filter to returns a timeseries with 1 when logs go missing.

Cyril Tovena	3f0800dc44	Add function label_replace. (#3047) ... You might be wondering why do we need label_replace when we already have label_format. Well for two reasons: 1. It's nice to have something similar to Prometheus, so users building metric queries will feel right at home. 2. Interestingly, they are quite different in how they execute. label_format executes for every log line, however label_replace execute for every sample. Since you aggregate log lines into sample then label_replace is way more efficient at scale. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com>	5 years ago
Cyril Tovena	4e7a123c77	Support rate for unwrap expressions. (#3048) ... This allows to bytes throughput if there were printed in a log line. Examples : ```logql sum by (device) (rate({app="network-dev"} |= "192.16.8.1" | json | unwrap recv_bytes [1m])) ``` Closes #3044 Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com>	5 years ago
Cyril Tovena	2406ea72bc	Allows by/without to be empty and available for max/min_over_time (#3030) ... * Allows by/without to be empty and available for max/min_over_time operations. This essentially allows to aggregate over all dimensions when using by () while without() is a noop. This also makes it possible for max and min range vector aggregation to use grouping, which is simpler than doing max by (foo) max_over_time(...) Examples: - `max_over_time(...) by ()` gives your the max over time accross of all series. - `min_over_time(...) by (namespace)` gives you the min over time per namespace. - `max_over_time(...) without (namespace)` gives you the max over time removing the namespace dimension. PS: I've also refactored a bit how we optimized grouping to make it more clear. Fixes #2884 Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * nit doc.

I didn't introduce the error here because I think I would prefer a success in this case. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com>	5 years ago
Cyril Tovena	ec725db9d0	Add ProcessString to Pipeline. (#2972) ... * Add ProcessString to Pipeline. Most of the time, you have a buffer that you want to test again a log pipeline, when it passed you usually copy via string(buff). In some cases like headchunk and tailer you already have an allocated immutable string, since pipeline never mutate the line passed as parameter, we can create ProcessString pipeline method that will avoid re-allocating the line. benchmp: ``` ❯ benchcmp before.txt after.txt benchmark old ns/op new ns/op delta BenchmarkHeadBlockIterator/Size_100000-16 20264242 16112591 -20.49% BenchmarkHeadBlockIterator/Size_50000-16 10186969 7905259 -22.40% BenchmarkHeadBlockIterator/Size_15000-16 3229052 2202770 -31.78% BenchmarkHeadBlockIterator/Size_10000-16 1916537 1392355 -27.35% BenchmarkHeadBlockSampleIterator/Size_100000-16 18364773 16106425 -12.30% BenchmarkHeadBlockSampleIterator/Size_50000-16 8988422 7730226 -14.00% BenchmarkHeadBlockSampleIterator/Size_15000-16 2788746 2306161 -17.30% BenchmarkHeadBlockSampleIterator/Size_10000-16 1773766 1488861 -16.06% benchmark old allocs new allocs delta BenchmarkHeadBlockIterator/Size_100000-16 200039 39 -99.98% BenchmarkHeadBlockIterator/Size_50000-16 100036 36 -99.96% BenchmarkHeadBlockIterator/Size_15000-16 30031 31 -99.90% BenchmarkHeadBlockIterator/Size_10000-16 20029 29 -99.86% BenchmarkHeadBlockSampleIterator/Size_100000-16 100040 40 -99.96% BenchmarkHeadBlockSampleIterator/Size_50000-16 50036 36 -99.93% BenchmarkHeadBlockSampleIterator/Size_15000-16 15031 31 -99.79% BenchmarkHeadBlockSampleIterator/Size_10000-16 10029 29 -99.71% benchmark old bytes new bytes delta BenchmarkHeadBlockIterator/Size_100000-16 27604042 21203941 -23.19% BenchmarkHeadBlockIterator/Size_50000-16 13860654 10660652 -23.09% BenchmarkHeadBlockIterator/Size_15000-16 4231360 3271363 -22.69% BenchmarkHeadBlockIterator/Size_10000-16 2633436 1993420 -24.30% BenchmarkHeadBlockSampleIterator/Size_100000-16 17799137 14598973 -17.98% BenchmarkHeadBlockSampleIterator/Size_50000-16 7433260 5833137 -21.53% BenchmarkHeadBlockSampleIterator/Size_15000-16 2258099 1778096 -21.26% BenchmarkHeadBlockSampleIterator/Size_10000-16 1393600 1073605 -22.96% ``` Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * add some precision about why Sum64 is not a concern.

Unfortunately before the code was building iterators while advancing previous one, building iterator can advance iterator and thus creates a race condition. This changeset make sure we only fetch chunks in advance and build iterator and iterate over them in sequence. Also add support for labels in the cacheIterator which is required for logqlv2.

Cyril Tovena	cd74043db9	Improve entry deduplication. (#2302) ... * Improve entry deduplication. This PR removes mostcommon and sort insert function in the heap iterator. I discovered while working on #2293 that those are actually not helping since we're deduping those lines anyways. There were no tests checking if deduping was correctly working so I did added those. Bonus point this means deduping will run faster and the code is less complex. The only side effect is that the order of entries that are at the same timestamp, before the most common entry would appear first, now we keep the same order as we stored them, which I think is better. I also change the label ordering, I think whether we are forward or backward we should keep the same aphabetical labels ordering not sure why direction was altering this before.
