Oleg Zaytsev	3ded84e649	Fix TestCancelCompactions on windows It seems that readOnlyDB was still opened which blocked the temp dir cleanup. Also changed the copy dir to be another TempDir instead of manually creating one. Signed-off-by: Oleg Zaytsev <mail@olegzaytsev.com>	2 years ago

Oleg Zaytsev	6e2905a4d4	Use zeropool.Pool to workaround SA6002 (#12189 ) * Use zeropool.Pool to workaround SA6002 I built a tiny library called https://github.com/colega/zeropool to workaround the SA6002 staticheck issue. While searching for the references of that SA6002 staticheck issues on Github first results was Prometheus itself, with quite a lot of ignores of it. This changes the usages of `sync.Pool` to `zeropool.Pool[T]` where a pointer is not available. Also added a benchmark for HeadAppender Append/Commit when series already exist, which is one of the most usual cases IMO, as I didn't find any.

Oleg Zaytsev	344c630857	Fix context.Canceled wrapping in compaction We need to make sure that `tsdb_errors.NewMulti` handles the errors.Is() calls properly, like it's done in grafana/dskit. Also we need to check that `errors.Is(err, context.Canceled)`, not that `err == context.Canceled`. Signed-off-by: Oleg Zaytsev <mail@olegzaytsev.com>	2 years ago

Đurica Yuri Nikolić	c9b85afd93	Making the number of CPUs used for WAL replay configurable (#12066 ) Adds `WALReplayConcurrency` as an option on tsdb `Options` and `HeadOptions`.

Ganesh Vernekar	66da1d51fd	Merge pull request #12003 from codesome/redundant-chunk-access Remove unnecessary chunk fetch in Head queries	2 years ago
Ganesh Vernekar	d504c950a2	Remove unnecessary chunk fetch in Head queries `safeChunk` is only obtained from the `headChunkReader.Chunk` call where the chunk is already fetched and stored with the `safeChunk`. So, when getting the iterator for the `safeChunk`, we don't need to get the chunk again. Also removed a couple of unnecessary fields from `safeChunk` as a part of this.

Ganesh Vernekar	8e8b718365	Merge pull request #11858 from fayzal-g/fix-chunks-metrics tsdb: when reading WAL, correctly update chunksRemoved and chunks metrics	2 years ago
beorn7	1cfc8f65a3	histograms: Return actually useful counter reset hints This is a bit more conservative than we could be. As long as a chunk isn't the first in a block, we can be pretty sure that the previous chunk won't disappear. However, the incremental gain of returning NotCounterReset in these cases is probably very small and might not be worth the code complications. Wwith this, we now also pay attention to an explicitly set counter reset during ingestion. While the case doesn't show up in practice yet, there could be scenarios where the metric source knows there was a counter reset even if it might not be visible from the values in the histogram. It is also useful for testing. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago
beorn7	57c18420ab	histograms: General readability tweaks - Adjust doc comments to go1.19 style. - Break down some overly long lines. - Minor doc comment tweaks and fixes. - Some renaming. Some rationales for the last point: I have renamed “interjections” into “inserts”, mostly because it is shorter, and the word shows up a lot by now (and the concept is cryptic enough to not obfuscate it even more with abbreviations). I have also tried to find more descriptive naming for the “compare spans” functions. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago

Ganesh Vernekar	cb2be6e62f	Merge pull request #11779 from codesome/memseries-ooo tsdb: Only initialise out-of-order fields when required	2 years ago
Jesus Vazquez	136956cca4	Attempt to append ooo sample at the end first (#11615 ) This is an optimization on the existing append in OOOChunk. What we've been doing so far is find the place inside the out-of-order slice where the new sample should go in and then place it there and move any samples to the right if necessary. This is OK but requires a binary search every time the slice is bigger than 0. The optimization is opinionated and suggests that although out-of-order samples can be out-of-order amongst themselves they'll probably be in order thus we can probably optimistically append at the end and if not do the binary search. OOOChunks are capped to 30 samples by default so this is a small optimization but everything adds up, specially if you handle many active timeseries with out-of-order samples.
