From 14d4b5aa8361e3ed396717d7cc659391ff1a7384 Mon Sep 17 00:00:00 2001 From: Aliaksandr Valialkin Date: Fri, 27 Aug 2021 17:15:29 +0300 Subject: [PATCH] app/vmselect: add `-search.disableAutoCacheReset` command-line option for disabling automatic cache reset when a sample with old timestamp outside -search.cacheTimestampOffset is inserted See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1570 --- docs/CHANGELOG.md | 1 + 1 file changed, 1 insertion(+) diff --git a/docs/CHANGELOG.md b/docs/CHANGELOG.md index b0835bb770..6b0480590a 100644 --- a/docs/CHANGELOG.md +++ b/docs/CHANGELOG.md @@ -12,6 +12,7 @@ sort: 15 * FEATURE: vmalert: add `-disableAlertgroupLabel` command-line flag for disabling the label with alert group name. This may be needed for proper deduplication in Alertmanager. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1532). * FEATURE: update Go builder from v1.16.7 to v1.17.0. This improves data ingestion and query performance by up to 5% according to benchmarks. See [the release post for Go1.17](https://go.dev/blog/go1.17). * FEATURE: vmagent: expose `promscrape_discovery_http_errors_total` metric, which can be used for monitoring the number of failed discovery attempts per each `http_sd` config. +* FEATURE: do not reset response cache when a sample with old timestamp is ingested into VictoriaMetrics if `-search.disableAutoCacheReset` command-line option is set. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1570). * BUGFIX: rename `sign` function to `sgn` in order to be consistent with PromQL. See [this pull request from Prometheus](https://github.com/prometheus/prometheus/pull/8457). * BUGFIX: improve the detection of the needed free space for background merge operation. This should prevent from possible out of disk space crashes during big merges. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1560).
