Matthias Rampke	78f2645787	test(tsdb): break up repeated test to avoid timeout (#10671 ) On macOS, the TestTombstoneCleanRetentionLimitsRace performs very poorly. It takes more than a second to write out one block, and as it writes 400 of them, we run into the 10-minute test timeout frequently. While this doesn't fix the actual performance issue, breaking each iteration into a subtest makes the test pass reliably (because each iteration comfortably finishes in under a minute).

Bryan Boreham	4b9f248e85	unit tests: make all Labels sorted alphabetically (#10532 ) "Labels is a sorted set of labels. 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.

Oleg Zaytsev	af0f6da5cb	Fix chunk overflow appending samples at a variable rate (#10607 ) * Add a test with variable samples rate append This test overflows the chunk created in memseries, and the total amount of samples in the (only) mmapped chunk is 29, instead of the 65565 appended ones. Signed-off-by: Oleg Zaytsev <mail@olegzaytsev.com> * Cut new chunk when rate prediction was wrong When appending samples at a slow rate, and then appending at a higher rate, the prediction we made to cut a new chunk is no longer valid. Sometimes this can even cause an overflow in the chunk, if more samples than uint16 can hold are appended.

Robert Fratto	286dfc70b7	tsdb/agent: port grafana/agent#676 (#10587 ) * tsdb/agent: port grafana/agent#676 grafana/agent#676 fixed an issue where a loading a WAL with multiple segments may result in ref ID collision. The starting ref ID for new series should be set to the highest ref ID across all series records from all WAL segments. This fixes an issue where the starting ref ID was incorrectly set to the highest ref ID found in the newest segment, which may not have any ref IDs at all if no series records have been appended to it yet.

Bryan Boreham	2c1be4df7b	tsdb: more efficient sorting of postings read from WAL at startup (#10500 ) * tsdb: avoid slice-to-interface allocation in EnsureOrder This is pulling the `seriesRefSlice` out of the loop, so the compiler doesn't allocate a new one on the heap every time. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * tsdb: use pointer type in Pool for EnsureOrder As noted by staticcheck, Pool prefers the objects in the pool to have pointer type. This is a little more fiddly to code, but avoids allocation of a wrapper object every time a slice is put into the pool. Removed a comment that said fixing this has a performance penalty: not borne out by benchmarks. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	3 years ago

Mauro Stettler	0df3489275	Write chunks via queue, predicting the refs (#10051 ) * Write chunks via queue, predicting the refs Our load tests have shown that there is a latency spike in the remote write handler whenever the head chunks need to be written, because chunkDiskMapper.WriteChunk() blocks until the chunks are written to disk. This adds a queue to the chunk disk mapper which makes the WriteChunk() method non-blocking unless the queue is full. Reads can still be served from the queue.

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.

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.

Slightly slower than the expanding postings version for some cases, but definitely pays the price once the cardinality grows. Still offers 10x latency improvement where previous latencies were reaching 1s.

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

Oleg Zaytsev	5e746e4e88	Check postings bytes length when decoding (#9766 ) Added validation to expected postings length compared to the bytes slice length. With 32bit postings, we expect to have 4 bytes per each posting. If the number doesn't add up, we know that the input data is not compatible with our code (maybe it's cut, or padded with trash, or even written in a different coded). This is needed in downstream projects to correctly identify cached postings written with an unknown codec, but it's also a good idea to validate it here.

Sunil Thaha	a484a83d4a	fix: panic when checkpoint directory is empty (#9687 ) Calling `wal.NewSegmentBufReader()` without any segments would cause a `panic` resulting in prometheus crashing. This patch fixes the panic by making segmentBufReader return a EOF if there are not segments. This also means an empty checkpoint directory which should never be the case unless it has been tampered with (or has issues due to the underlying filesystem e.g. NFS) would be ignored by Prometheus and would continue to run instead of the current behaviour which is to panic.
