Cyril Tovena	a62f81f1cf	Improve tailer matcher function. (#2959 ) Don't create a map on every new push of a stream or appearance of a new stream. Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com>	5 years ago
Cyril Tovena	049c7acc12	Improve logql parser allocations. (#2927 ) * Improve logql parser allocations. Also moving labels parsing into logql package, and I'm not shy to say that promql is faster for this. So we're using promql for parser, it's faster because their lexer is more sophisticated than ours. Result are impressive. ``` ❯ benchcmp before.txt after.txt benchmark old ns/op new ns/op delta Benchmark_ParseLabels-16 24394 8745 -64.15% benchmark old allocs new allocs delta Benchmark_ParseLabels-16 156 20 -87.18% benchmark old bytes new bytes delta Benchmark_ParseLabels-16 24976 2099 -91.60% ``` Combined with #2926, I think we should be able to get rid of `util.ToClientLabels`.
