Add method `PostingsForLabelMatching` to `tsdb.IndexReader`, to obtain postings for labels with a certain name and values accepted by a provided callback, and use it from `tsdb.PostingsForMatchers`. The intention is to optimize regexp matcher paths, especially not having to load all label values before matching on them. Plus tests, and refactor some `tsdb/index.Reader` methods. Benchmarking shows memory reduction up to ~100%, and speedup of up to ~50%. Signed-off-by: Arve Knudsen <arve.knudsen@gmail.com> Co-authored-by: Bartlomiej Plotka <bwplotka@gmail.com> |
