Oleg Zaytsev	fe9cb5a803	Check context every 128 labels instead of 100 (#14118 ) Follow up on https://github.com/prometheus/prometheus/pull/14096 As promised, I bring a benchmark, which shows a very small improvement if context is checked every 128 iterations of label instead of every 100. It's much easier for a computer to check modulo 128 than modulo 100. This is a very small 0-2% improvement but I'd say this is one of the hottest paths of the app so this is still relevant.

Arve Knudsen	5c4310aa37	[ENHANCEMENT] TSDB: Optimize querying with regexp matchers Add method `PostingsForLabelMatching` to `tsdb.IndexReader`, to obtain postings for labels with a certain name and values accepted by a provided callback, and use it from `tsdb.PostingsForMatchers`. The intention is to optimize regexp matcher paths, especially not having to load all label values before matching on them. Plus tests, and refactor some `tsdb/index.Reader` methods.

Łukasz Mierzwa	277f04f0c4	Stop compactions if there's a block to write (#13754 ) * Stop compactions if there's a block to write db.Compact() checks if there's a block to write with HEAD chunks before calling db.compactBlocks(). This is to ensure that if we need to write a block then it happens ASAP, otherwise memory usage might keep growing. But what can also happen is that we don't need to write any block, we start db.compactBlocks(), compaction takes hours, and in the meantime HEAD needs to write out chunks to a block. This can be especially problematic if, for example, you run Thanos sidecar that's uploading block, which requires that compactions are disabled. Then you disable Thanos sidecar and re-enable compactions. When db.compactBlocks() is finally called it might have a huge number of blocks to compact, which might take a very long time, during which HEAD cannot write out chunks to a new block. In such case memory usage will keep growing until either: - compactions are finally finished and HEAD can write a block - we run out of memory and Prometheus gets OOM-killed This change adds a check for pending HEAD block writes inside db.compactBlocks(), so that we bail out early if there are still compactions to run, but we also need to write a new block. Also add a test for compactBlocks. --------- Signed-off-by: Łukasz Mierzwa <l.mierzwa@gmail.com> Signed-off-by: Lukasz Mierzwa <lukasz@cloudflare.com>	8 months ago

Nick Pillitteri	481f14e1c0	TSDB: Don't rely on integer overflow in head compaction check (#13755 ) * TSDB: Don't compact the head block when empty Don't compact the Head block if there have not yet been any samples appended. Previously, the logic for determining if the head should be compacted relied on the default values for min and max time and integer overflow when they were checked in `Head.compactable()`. The check in `Head.compactable()` effectively did `math.MinInt64 - math.MaxInt64` which overflowed and wrapped to `1`. Since `1` is less than `1.5` times the chunk range, compaction did not happen. This was the correct behavior but relying on overflow wrapping is surprising. This change add a method for checking if the min and max time for the head is unset and uses it to short-circuit compaction in that case. It also replaces several explicit checks for the default value to determine if the head has not yet had any samples added. Signed-off-by: Nick Pillitteri <nick.pillitteri@grafana.com>	8 months ago

Marco Pracucci	501bc6419e	Add ShardedPostings() support to TSDB (#10421 ) This PR is a reference implementation of the proposal described in #10420. In addition to what described in #10420, in this PR I've introduced labels.StableHash(). The idea is to offer an hashing function which doesn't change over time, and that's used by query sharding in order to get a stable behaviour over time. The implementation of labels.StableHash() is the hashing function used by Prometheus before stringlabels, and what's used by Grafana Mimir for query sharding (because built before stringlabels was a thing). Follow up work As mentioned in #10420, if this PR is accepted I'm also open to upload another foundamental piece used by Grafana Mimir query sharding to accelerate the query execution: an optional, configurable and fast in-memory cache for the series hashes.

Filip Petkovski	583f3e587c	Optimize histogram iterators (#13340 ) Optimize histogram iterators Histogram iterators allocate new objects in the AtHistogram and AtFloatHistogram methods, which makes calculating rates over long ranges expensive. In #13215 we allowed an existing object to be reused when converting an integer histogram to a float histogram. This commit follows the same idea and allows injecting an existing object in the AtHistogram and AtFloatHistogram methods. When the injected value is nil, iterators allocate new histograms, otherwise they populate and return the injected object. The commit also adds a CopyTo method to Histogram and FloatHistogram which is used in the BufferedIterator to overwrite items in the ring instead of making new copies. Note that a specialized HPoint pool is needed for all of this to work (`matrixSelectorHPool`). --------- Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com> Co-authored-by: George Krajcsovits <krajorama@users.noreply.github.com>	10 months ago

Giedrius Statkevičius	b695e069b8	tsdb/main: wire "EnableOverlappingCompaction" to tsdb.Options (#13398 ) This added the https://github.com/prometheus/prometheus/pull/13393 "EnableOverlappingCompaction" parameter to the compactor code but not to the tsdb.Options. I forgot about that. Add it to `tsdb.Options` too and set it to `true` in Prometheus.
