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>	2 years 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>	2 years ago
