Cyril Tovena	88feda41a0	Improve heap iterators. (#4731 ) Mostly improve allocations but I'm planning to do more using those benchmark. ``` name old time/op new time/op delta HeapIterator-16 3.87ms ± 6% 3.41ms ± 1% -11.92% (p=0.008 n=5+5) HeapSampleIterator-16 2.09ms ± 1% 2.09ms ± 1% ~ (p=0.421 n=5+5) name old alloc/op new alloc/op delta HeapIterator-16 10.5kB ± 0% 8.2kB ± 0% -21.88% (p=0.008 n=5+5) HeapSampleIterator-16 8.40kB ± 0% 6.10kB ± 0% -27.34% (p=0.000 n=5+4) name old allocs/op new allocs/op delta HeapIterator-16 12.0 ± 0% 5.0 ± 0% -58.33% (p=0.008 n=5+5) HeapSampleIterator-16 12.0 ± 0% 5.0 ± 0% -58.33% (p=0.008 n=5+5) ``` I want to introduce a difference between the need to dedupe vs order data. The later doesn't requires poping from the heap, we could actually use a sort.slice. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com>	4 years ago
Cyril Tovena	d81f757ecb	Refactor and simplify stats package. (#4712 ) * Refactor and simplify stats package. This PR refactors the stats package and make it smaller and simpler to work with. - It doesn't expose the context which can causes race when mutating it. - Uses concurrency primitive to ensure correctness - Replace trailers with in-batch statistics to propagate ingesters stats.

Cyril Tovena	4a8f62ba00	Improve head chunk allocations when reading samples. (#3968 ) * Improve head chunk allocations when reading samples. Reading sample is the worst because we are not limited and must return all of them. Re-using memory will helps ingesters read path. ``` ❯ benchcmp before.txt after.txt benchmark old ns/op new ns/op delta BenchmarkHeadBlockSampleIterator/Size_20000-16 2935102 1568140 -46.57% BenchmarkHeadBlockSampleIterator/Size_10000-16 1441980 750856 -47.93% BenchmarkHeadBlockSampleIterator/Size_8000-16 1146807 602796 -47.44% BenchmarkHeadBlockSampleIterator/Size_5000-16 698638 370655 -46.95% benchmark old allocs new allocs delta BenchmarkHeadBlockSampleIterator/Size_20000-16 32 16 -50.00% BenchmarkHeadBlockSampleIterator/Size_10000-16 29 15 -48.28% BenchmarkHeadBlockSampleIterator/Size_8000-16 28 15 -46.43% BenchmarkHeadBlockSampleIterator/Size_5000-16 26 15 -42.31% benchmark old bytes new bytes delta BenchmarkHeadBlockSampleIterator/Size_20000-16 2269664 484068 -78.67% BenchmarkHeadBlockSampleIterator/Size_10000-16 1073582 984 -99.91% BenchmarkHeadBlockSampleIterator/Size_8000-16 827825 819 -99.90% BenchmarkHeadBlockSampleIterator/Size_5000-16 475557 786 -99.83% ``` Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Improve unorderedHeadBlock too.

Cyril Tovena	e21d6edc10	Fixes 500 in the querier when returning multiple errors. (#3348 ) This correctly implement the `Is` error interface and uses the `util.MultiError` everywhere we need it. This way we can correcltly access if this was a cancellation which should not translate into 500. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com>	5 years ago
