Robert Fratto	a09465baee	storage/remote: disable resharding during active retry backoffs (#13562 ) * storage/remote: disable resharding during active retry backoffs Today, remote_write reshards based on pure throughput. This is problematic if throughput has been diminished because of HTTP 429s; increasing the number of shards due to backpressure will only exacerbate the problem. This commit disables resharding for twice the retry backoff, ensuring that resharding will never occur during an active backoff, and that resharding does not become enabled again until enough time has elapsed to allow any pending requests to be retried.

This int64 is only updated after updating the disabled timestamp if resharding was previously enabled.

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
Bryan Boreham	63cdd6dbe1	storage: skip merging when no remote storage configured Prometheus is hard-coded to use a fanout storage between TSDB and a remote storage which by default is empty. This change detects the empty storage and skips merging between result sets, which would make `Select()` sort results. Bottom line: we skip a sort unless there really is some remote storage configured. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	11 months ago

Fiona Liao	5bee0cfce2	Change `ChunkReader.Chunk()` to `ChunkOrIterable()` The ChunkReader interface's Chunk() has been changed to ChunkOrIterable(). This is a precursor to OOO native histogram support - with OOO native histograms, the chunks.Meta passed to Chunk() can result in multiple chunks being returned rather than just a single chunk (e.g. if oooMergedChunk has a counter reset in the middle). To support this, ChunkOrIterable() requires either a single chunk or an iterable to be returned. If an iterable is returned, the caller has the responsibility of converting the samples from the iterable into possibly multiple chunks. The OOOHeadChunkReader now returns an iterable rather than a chunk to prepare for the native histograms case. Also as a beneficial side effect, oooMergedChunk and boundedChunk has been simplified as they only need to implement the Iterable interface now, not the full Chunk interface. --------- Signed-off-by: Fiona Liao <fiona.y.liao@gmail.com> Co-authored-by: George Krajcsovits <krajorama@users.noreply.github.com>	1 year ago
