zenador	32ee1b15de	Fix error on ingesting out-of-order exemplars (#13021 ) Fix and improve ingesting exemplars for native histograms. See code comment for a detailed explanation of the algorithm. Note that this changes the current behavior for all kind of samples slightly: We now allow exemplars with the same timestamp as during the last scrape if the value or the labels have changed. Also note that we now do not ingest exemplars without timestamps for native histograms anymore.

beorn7	0e3f35324b	scrape: Enable ingestion of multiple exemplars per sample This has become a requirement for native histograms, as a single histogram sample commonly has many buckets, so that providing many exemplars makes sense. Since OM text doesn't support native histograms yet, the test had to be expanded to also support protobuf test cases. Signed-off-by: beorn7 <beorn@grafana.com>	1 year ago

Bryan Boreham	82860a770c	tsdb: use simpler map key to improve exemplar ingest performance (#10111 ) * tsdb: fix exemplar benchmarks Go benchmarks are expected to do an amount of work that varies with the `b.N` parameter. Previously these benchmarks would report a result like 0.01 ns/op, which is nonsense. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * tsdb: use simpler map key to improve exemplar perf Prometheus holds an index of exemplars so it can discard the oldest one for a series when a new one is added. Since the keys are not for human eyes, we can use a simpler format and save the effort of quoting label values. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Exemplars: allocate index map with estimated size This avoids Go having to re-size the map several times as it grows. 16 exemplars per series is a guess; if it is too low then the map will be sparse, while if it is too high then the map will have to resize once or twice.
