Aliaksandr Valialkin	29e53b9f55	app/vmselect/promql: consistency update after `93fbd0c54b`	2022-07-13 12:33:14 +03:00
Roman Khavronenko	93fbd0c54b	promql: return `step` as scrapeInterval when it can't be calculated (#2865 ) The change allows to specify default value for `getScrapeInterval` function when actual interval can't be calculated. Before the change, function were returning `maxSilenceInterval` (5m) in such cases, which may be not correct for instant queries processing. The specific scenario where using `maxSilenceInterval` caused issues is the following: 1. Series becomes stale; 2. Client (in this case vmalert) continues to request series every 15s; 3. Database returns empty results as expected; 4. But at some specific moment of time database returns datapoints from `now()-5m`, because lookback window was extended to `maxSilenceInterval`.

Aliaksandr Valialkin	a350d1e81c	lib/storage: return marshaled metric names from SearchMetricNames Previously SearchMetricNames was returning unmarshaled metric names.

While at it, remove possible duplicate metric names, which could occur when multiple samples for new time series are ingested via concurrent requests.

Roman Khavronenko	723d90536c	vmselect: limit `end` param max value by 2d in future (#2729 ) * vmselect: limit `end` param max value by 2d in future The change is applied only to service handlers like `/labels` or `/series` and limits the `end` param by max value <= now() + 2 days. The same limit is applied for the ingested data, so no reason to allow to request data in future far than that. The change is also needed for corner cases like https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2669 where too high `end` value triggers inefficient global index search.

Aliaksandr Valialkin	f4989edd96	lib/bytesutil: split Resize() into ResizeNoCopy() and ResizeWithCopy() functions Previously bytesutil.Resize() was copying the original byte slice contents to a newly allocated slice. This wasted CPU cycles and memory bandwidth in some places, where the original slice contents wasn't needed after slize resizing. Switch such places to bytesutil.ResizeNoCopy(). Rename the original bytesutil.Resize() function to bytesutil.ResizeWithCopy() for the sake of improved readability. Additionally, allocate new slice with `make()` instead of `append()`. This guarantees that the capacity of the allocated slice exactly matches the requested size. The `append()` could return a slice with bigger capacity as an optimization for further `append()` calls. This could result in excess memory usage when the returned byte slice was cached (for instance, in lib/blockcache).

Aliaksandr Valialkin	3f85c06b65	app/vmselect/netstorage: reduce CPU contention when upacking time series blocks by unpacking batches of such blocks instead of a single block This should improve query performance on systems with big number of CPU cores (16 and more)	2020-08-06 17:50:17 +03:00

Aliaksandr Valialkin	f0c678c41b	app/vmselect: do not adjust `start` and `end` query args passed to `/api/v1/query_range` when `-search.disableCache` command-line flag is set Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/563	2020-07-30 23:14:37 +03:00
Aliaksandr Valialkin	328b52e5ff	app/vmselect/promql: return non-empty value from `rate_over_sum(m[d])` even if a single data point is located in the given `[d]` window Just divide the data point value by the window duration in this case.	2020-07-29 12:37:58 +03:00
Aliaksandr Valialkin	700737c181	app/vmselect/promql: remove rollupFuncArg.realPrevValue handling, since the corner case in `increase()` is handled in another way now See `e00cfc854d` for the approach used now.	2020-07-29 12:37:58 +03:00
Aliaksandr Valialkin	2f735f112d	app/vmselect/promql: fill gaps with 0 in `rate_over_sum` response when the last value before the selected time window isnt empty	2020-07-29 12:37:58 +03:00

Aliaksandr Valialkin	894dcb7c1c	app/vmselect/promql: improve further the accuracy of buckets_limit() function The accuracy is increased by mergin the smallest bucket with the smallest adjacent bucket.	2020-07-26 12:10:13 +03:00
Aliaksandr Valialkin	edb1eca6f1	app/vmselect/promql: avoid dropping `inf` bucket in `buckets_limit` The `le="inf"` bucket must be preserved in order to maintain the maximum level of accuracy.	2020-07-25 17:00:36 +03:00
Aliaksandr Valialkin	97b6f5d223	app/vmselect/promql: optimize `buckets_limit(k, buckets)` for big number of buckets	2020-07-25 13:24:03 +03:00
Aliaksandr Valialkin	bb161497cf	app/vmselect/promql: improve the accuracy of `buckets_limit(k, buckets)` function Now it properly merges the bucket with the previous bucket after deletion.	2020-07-24 17:07:49 +03:00
Aliaksandr Valialkin	994fa2f3bf	app/vmselect/promql: add `buckets_limit(k, buckets)` function, which limits the number of buckets per time series to `k` This function works with both Prometheus-style and VictoriaMetrics-style buckets.

Aliaksandr Valialkin	3e557c9861	app/vmselect/promql: add `rate_over_sum(m[d])` function to MetricsQL, which returns rate over sum of `m` values over `d` duration Something like `sum_over_time(m[d]) / d`, but more accurate.	2020-07-24 01:17:42 +03:00
Aliaksandr Valialkin	b1f6843bd0	app/vmselect/promql: allow setting `[d]` window smaller than the interval between raw points for `avg_over_time` This makes `avg_over_time` behavior consistent with `sum_over_time` and `count_over_time` behaviors. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/636	2020-07-23 22:25:43 +03:00
Aliaksandr Valialkin	039c9d2441	lib/storage: respect `-search.maxQueryDuration` when searching for time series in inverted index Previously the time spent on inverted index search could exceed the configured `-search.maxQueryDuration`. This commit stops searching in inverted index on query timeout.	2020-07-23 21:21:42 +03:00
Aliaksandr Valialkin	2a45871823	lib/storage: add more fine-grained pace limiting for search	2020-07-23 19:26:08 +03:00

Aliaksandr Valialkin	4f526cc816	app/vmselect/prometheus: support `d`, `w` and `y` suffixes for durations passed to `step` in `/api/v1/query_range` like Prometheus does Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/641	2020-07-22 16:26:18 +03:00
Aliaksandr Valialkin	dfb113f175	app/vmselect/netstorage: reduce memory allocations when unpacking time series data by using a pool for unpackWork entries This should slightly reduce load on GC when processing queries that touch big number of time series. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/646 according to the provided memory profile there.	2020-07-22 15:03:57 +03:00
Aliaksandr Valialkin	caa2952aa6	app/vmselect: take into account the time spent in wait queue before query execution as time spent on the query	2020-07-21 19:00:09 +03:00
Aliaksandr Valialkin	e00cfc854d	app/vmselect/promql: skip the first value in time series passed to `increase()` if it exceeds by more than 10x the delta between the next value and the first value This should prvent from inflated `increase()` results for time series that start from big initial values. Such cases may occur when a label value changes in a metric without counter reset.	2020-07-21 17:24:10 +03:00
