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.

George Krajcsovits	39a35d92bc	tsdb/head: wlog exemplars after samples (#13113 ) When samples are committed in the head, they are also written to the WAL. The order of WAL records should be sample then exemplar, but this was not the case for native histogram samples. This PR fixes that. The problem with the wrong order is that remote write reads the WAL and sends the recorded timeseries in the WAL order, which means exemplars arrived before histogram samples. If the receiving side is Prometheus TSDB and the series has not existed before then the exemplar does not currently create the series. Which means the exemplar is rejected and lost.

Bryan Boreham	e6c0f69f98	TSDB: Only pay for hash collisions when they happen Instead of a map of slices of `memSeries`, ready for any of them to hold series where hash values collide, split into a map of `memSeries` and a map of slices which is usually empty, since hash collisions are a one-in-a-billion thing.

zenador	69edd8709b	Add warnings (and annotations) to PromQL query results (#12152 ) Return annotations (warnings and infos) from PromQL queries This generalizes the warnings we have already used before (but only for problems with remote read) as "annotations". Annotations can be warnings or infos (the latter could be false positives). We do not treat them different in the API for now and return them all as "warnings". It would be easy to distinguish them and return infos separately, should that appear useful in the future. The new annotations are then used to create a lot of warnings or infos during PromQL evaluations. Partially these are things we have wanted for a long time (e.g. inform the user that they have applied `rate` to a metric that doesn't look like a counter), but the new native histograms have created even more needs for those annotations (e.g. if a query tries to aggregate float numbers with histograms). The annotations added here are not yet complete. A prominent example would be a warning about a range too short for a rate calculation. But such a warnings is more tricky to create with good fidelity and we will tackle it later. Another TODO is to take annotations into account when evaluating recording rules. --------- Signed-off-by: Jeanette Tan <jeanette.tan@grafana.com>	1 year ago
