* Add unittests for PostingsForMatcher. * Selector methods are all stateless, don't need a reference. * Be smarter in how we look at matchers. Look at all matchers to see if a label can be empty. Optimise Not handling, so i!="2" is a simple lookup rather than an inverse postings list. All all the Withouts together, rather than having to subtract each from all postings. Change the pre-expand the postings logic to always do it before doing a Without only. Don't do that if it's already a list. The initial goal here was that the oft-seen pattern i=~"something.+",i!="foo",i!="bar" becomes more efficient. benchmark old ns/op new ns/op delta BenchmarkHeadPostingForMatchers/n="1"-4 5888 6160 +4.62% BenchmarkHeadPostingForMatchers/n="1",j="foo"-4 7190 6640 -7.65% BenchmarkHeadPostingForMatchers/j="foo",n="1"-4 6038 5923 -1.90% BenchmarkHeadPostingForMatchers/n="1",j!="foo"-4 6030884 4850525 -19.57% BenchmarkHeadPostingForMatchers/i=~".*"-4 887377940 230329137 -74.04% BenchmarkHeadPostingForMatchers/i=~".+"-4 490316101 319931758 -34.75% BenchmarkHeadPostingForMatchers/i=~""-4 594961991 130279313 -78.10% BenchmarkHeadPostingForMatchers/i!=""-4 537542388 318751015 -40.70% BenchmarkHeadPostingForMatchers/n="1",i=~".*",j="foo"-4 10460243 8565195 -18.12% BenchmarkHeadPostingForMatchers/n="1",i=~".*",i!="2",j="foo"-4 44964267 8561546 -80.96% BenchmarkHeadPostingForMatchers/n="1",i!="",j="foo"-4 42244885 29137737 -31.03% BenchmarkHeadPostingForMatchers/n="1",i=~".+",j="foo"-4 35285834 32774584 -7.12% BenchmarkHeadPostingForMatchers/n="1",i=~"1.+",j="foo"-4 8951047 8379024 -6.39% BenchmarkHeadPostingForMatchers/n="1",i=~".+",i!="2",j="foo"-4 63813335 30672688 -51.93% BenchmarkHeadPostingForMatchers/n="1",i=~".+",i!~"2.*",j="foo"-4 45381112 44924397 -1.01% Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> |
