Cyril Tovena	e8cce09de2	Fix a bug with metric queries and label_format. (#3263 ) * Fix a bug whith metric queries and label_format. In my previous PR where I introduced hints, I forgot to implement label format label required. This would cause label format label to be skipped during parsing. I've also took the opportunity to improve the code. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Refactor and add more tests. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com>	4 years ago
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.

Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com> * Fixes race conditions in the batch iterator. We should never advance an iterator in parallel. 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.
