Jesus Vazquez	c1b669bf9b	Add out-of-order sample support to the TSDB (#11075 ) * Introduce out-of-order TSDB support This implementation is based on this design doc: https://docs.google.com/document/d/1Kppm7qL9C-BJB1j6yb6-9ObG3AbdZnFUBYPNNWwDBYM/edit?usp=sharing This commit adds support to accept out-of-order ("OOO") sample into the TSDB up to a configurable time allowance. If OOO is enabled, overlapping querying are automatically enabled. Most of the additions have been borrowed from https://github.com/grafana/mimir-prometheus/ Here is the list ist of the original commits cherry picked from mimir-prometheus into this branch: - `4b2198d7ec` - `2836e5513f` - `00b379c3a5` - `ff0dc75758` - `a632c73352` - `c6f3d4ab33` - `5e8406a1d4` - `abde1e0ba1` - `e70e769889` - `df59320886` Co-authored-by: Jesus Vazquez <jesus.vazquez@grafana.com> Co-authored-by: Ganesh Vernekar <ganeshvern@gmail.com> Co-authored-by: Dieter Plaetinck <dieter@grafana.com> Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * gofumpt files Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Add license header to missing files Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Fix OOO tests due to existing chunk disk mapper implementation Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Fix truncate int overflow Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Add Sync method to the WAL and update tests Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * remove useless sync Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Update minOOOTime after truncating Head * Update minOOOTime after truncating Head Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> * Fix lint Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> * Add a unit test Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Load OutOfOrderTimeWindow only once per appender Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Fix OOO Head LabelValues and PostingsForMatchers Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Fix replay of OOO mmap chunks Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> * Remove unnecessary err check Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Prevent panic with ApplyConfig Signed-off-by: Ganesh Vernekar 15064823+codesome@users.noreply.github.com Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Run OOO compaction after restart if there is OOO data from WBL Signed-off-by: Ganesh Vernekar 15064823+codesome@users.noreply.github.com Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Apply Bartek's suggestions Co-authored-by: Bartlomiej Plotka <bwplotka@gmail.com> Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Refactor OOO compaction Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> * Address comments and TODOs - Added a comment explaining why we need the allow overlapping compaction toggle - Clarified TSDBConfig OutOfOrderTimeWindow doc - Added an owner to all the TODOs in the code Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Run go format Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Fix remaining review comments Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> * Fix tests Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> * Change wbl reference when truncating ooo in TestHeadMinOOOTimeUpdate Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> * Fix TestWBLAndMmapReplay test failure on windows Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> * Address most of the feedback Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> * Refactor the block meta for out of order Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> * Fix windows error Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> * Fix review comments Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> Signed-off-by: Jesus Vazquez <jesus.vazquez@grafana.com> Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com> Signed-off-by: Ganesh Vernekar 15064823+codesome@users.noreply.github.com Co-authored-by: Ganesh Vernekar <15064823+codesome@users.noreply.github.com> Co-authored-by: Ganesh Vernekar <ganeshvern@gmail.com> Co-authored-by: Dieter Plaetinck <dieter@grafana.com> Co-authored-by: Oleg Zaytsev <mail@olegzaytsev.com> Co-authored-by: Bartlomiej Plotka <bwplotka@gmail.com>	2 years ago

When checking for cache entries though, we used p.Series() as the key, which included the metric name _with_ its labels. That meant that we were never actually hitting the cache. We're fixing this by utiling the __name__ internal label for correctly getting the cache entries after they've been set by setHelp(), setType() or setUnit().

Order has to be guaranteed upon instantiation." says the comment, so fix all the tests that break this rule. For `BenchmarkLabelValuesWithMatchers()` and `BenchmarkHeadLabelValuesWithMatchers()` the amount of work done changes significantly if you put the labels in order, because all series refs get neatly partitioned by the `tens` label, so I renamed the labels to maintain the previous behaviour.

Chris Marchbanks	e970acb085	Fix deadlock between adding to queue and getting batch Do not block when trying to write a batch to the queue. This can cause appends to lock forever if the only thing reading from the queue needs the mutex to write.

Chris Marchbanks	bfb1500a38	Fix deadlock when stopping a shard (#10279 ) If a queue is stopped and one of its shards happens to hit the batch_send_deadline at the same time a deadlock can occur where stop holds the mutex and will not release it until the send is finished, but the send needs the mutex to retrieve the most recent batch. This is fixed by using a second mutex just for writing. In addition, the test I wrote exposed a case where during shutdown a batch could be sent twice due to concurrent calls to queue.Batch() and queue.FlushAndShutdown(). Protect these with a mutex as well. Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>	3 years ago

Goutham Veeramachaneni	1af81dc5c9	Update sent timestamp when write irrecoverably fails. We have an alert that fires when prometheus_remote_storage_highest_timestamp_in_seconds - prometheus_remote_storage_queue_highest_sent_timestamp_seconds becomes too high. But we have an agent that fires this when the remote "rate-limits" the user. This is because prometheus_remote_storage_queue_highest_sent_timestamp_seconds doesn't get updated when the remote sends a 429. I think we should update the metrics, and the change I made makes sense. Because if the requests fails because of connectivity issues, etc. we will never exit the `sendWriteRequestWithBackoff` function. It only exits the function when there is a non-recoverable error, like a bad status code, and in that case, I think the metric needs to be updated.

Björn Rabenstein	d677aa4b29	storage: Consolidate iterator method names (Values -> At) (#9888 ) `BufferedSeriesIterator` and `MemoizedSeriesIterator` use a method called `Values` for exactly the purpose for which all other iterators of the same kind use a method called `At`. That alone is confusing, but on top of that, the `Values` method only returns a single sample, not multiple values. I assume the naming has historical reasons. This commit makes it more consistent. It is now easier to read, and now `BufferedSeriesIterator` and `MemoizedSeriesIterator` implement `chunkenc.Iterator` like many other iterators, too.

Dieter Plaetinck	cda025b5b5	TSDB: demistify SeriesRefs and ChunkRefs (#9536 ) * TSDB: demistify seriesRefs and ChunkRefs The TSDB package contains many types of series and chunk references, all shrouded in uint types. Often the same uint value may actually mean one of different types, in non-obvious ways. This PR aims to clarify the code and help navigating to relevant docs, usage, etc much quicker. Concretely: * Use appropriately named types and document their semantics and relations. * Make multiplexing and demuxing of types explicit (on the boundaries between concrete implementations and generic interfaces). * Casting between different types should be free. None of the changes should have any impact on how the code runs.
