Aliaksandr Valialkin	919939ee9f	app/vmselect/promql: consistency update after `93fbd0c54b`	2022-07-13 12:34:28 +03:00
Roman Khavronenko	214e01499c	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	7d5d33fd71	lib/storage: return marshaled metric names from SearchMetricNames Previously SearchMetricNames was returning unmarshaled metric names. This wasn't great for vmstorage, which should spend additional CPU time for marshaling the metric names before sending them to vmselect. While at it, remove possible duplicate metric names, which could occur when multiple samples for new time series are ingested via concurrent requests. Also sort the metric names before returning them to the client. This simplifies debugging of the returned metric names across repeated requests to /api/v1/series	2022-06-28 18:16:32 +03:00

hagen1778	e40d015e9a	vmselect: make `vm_partial_results_total` consistent Metrics `vm_partial_results_total` and `vm_requests_total` serving the similar purpose, but contain inconsistent set of labels. This change updates `vm_partial_results_total` labels to be consistent with `vm_requests_total`. The change breaks backward compatibility with assumption that `vm_partial_results_total` wasn't widely used, since it is not documented and absent in the alerts and dashboards.

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	6232eaa938	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	8c37b63ea9	Revert "app/vmselect/promql: remove metric name from results of certain rollup functions in order to be consistent with Prometheus" This reverts commit `e5202a4eae`. Reason for revert: the previous behavior for VictoriaMetrics is easier to understand and use by users - functions, which don't change the meaning of the time series shouldn't drop metric name. Now the following functions do not drop metric name: * max_over_time * min_over_time * avg_over_time * quantile_over_time * geomean_over_time * mode_over_time * holt_winters * predict_linear Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/674	2020-10-12 11:48:38 +03:00
