Björn Rabenstein	b866db009b	storage: Fix and improve the Seek method of various iterators (#9878 ) There was a subtle and nasty bug in listSeriesIterator.Seek. In addition, the Seek call is defined to be a no-op if the current position of the iterator is already pointing to a suitable sample. This commit adds fast paths for this case to several potentially expensive Seek calls. Another bug was in concreteSeriesIterator.Seek. It always searched the whole series and not from the current position of the iterator. Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago

Bryan Boreham	5afa606ecb	Remote-write: reuse memory for marshalling (#9412 ) By holding a `proto.Buffer` per shard and passing it down to where marshalling is done, we avoid creating a lot of garbage. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	3 years ago

Tom Wilkie	d479151f1f	Various enhancements and refactorings for remote write receiver: - Remove unrelated changes - Refactor code out of the API module - that is already getting pretty crowded. - Don't track reference for AddFast in remote write. This has the potential to consume unlimited server-side memory if a malicious client pushes a different label set for every series. For now, its easier and safer to always use the 'slow' path. - Return 400 on out of order samples. - Use remote.DecodeWriteRequest in the remote write adapters. - Put this behing the 'remote-write-server' feature flag - Add some (very) basic docs. - Used named return & add test for commit error propagation Signed-off-by: Tom Wilkie <tom.wilkie@gmail.com>	4 years ago
gotjosh	4eca4dffb8	Allow metric metadata to be propagated via Remote Write. (#6815 ) * Introduce a metadata watcher Similarly to the WAL watcher, its purpose is to observe the scrape manager and pull metadata. Then, send it to a remote storage.

Bartlomiej Plotka	fe802f29c9	storage: Removed SelectSorted method; Simplified interface; Added requirement for remote read to sort response. This is technically BREAKING CHANGE, but it was like this from the beginning: I just notice that we rely in Prometheus on remote read being sorted. This is because we use selected data from remote reads in MergeSeriesSet which rely on sorting. I found during work on https://github.com/prometheus/prometheus/pull/5882 that we do so many repetitions because of this, for not good reason. I think I found a good balance between convenience and readability with just one method. Smaller the interface = better. Also I don't know what TestSelectSorted was testing, but now it's testing sorting. Signed-off-by: Bartlomiej Plotka <bwplotka@gmail.com>	5 years ago

Julius Volz	9f10c63cff	Fix remote read labelset corruption (#3456 ) The labelsets returned from remote read are mutated in higher levels (like seriesFilter.Labels()) and since the concreteSeriesSet didn't return a copy, the external mutation affected the labelset in the concreteSeries itself. This resulted in bizarre bugs where local and remote series would show with identical label sets in the UI, but not be deduplicated, since internally, a series might come to look like: {__name__="node_load5", instance="192.168.1.202:12090", job="node_exporter", node="odroid", node="odroid"} (note the repetition of the last label)	7 years ago
