From e44532b760d487a8cc55ae86b9fb1c8d90b593c8 Mon Sep 17 00:00:00 2001 From: Aliaksandr Valialkin Date: Tue, 9 Mar 2021 13:12:01 +0200 Subject: [PATCH] docs/CHANGELOG.md: mention about improved query performance at https://github.com/VictoriaMetrics/VictoriaMetrics/commit/18fe0ff14bc78860c5569e2b70de1db78fac61be --- docs/CHANGELOG.md | 2 ++ 1 file changed, 2 insertions(+) diff --git a/docs/CHANGELOG.md b/docs/CHANGELOG.md index fdfbdcd814..7a4fb6f238 100644 --- a/docs/CHANGELOG.md +++ b/docs/CHANGELOG.md @@ -6,10 +6,12 @@ - `histogram_avg(buckets)` - returns the average value for the given buckets. - `histogram_stdvar(buckets)` - returns standard variance for the given buckets. - `histogram_stddev(buckets)` - returns standard deviation for the given buckets. +* FEATURE: reduce median query duration by up to 2x. See https://github.com/VictoriaMetrics/VictoriaMetrics/commit/18fe0ff14bc78860c5569e2b70de1db78fac61be * FEATURE: vmagent: add ability to replicate scrape targets among `vmagent` instances in the cluster with `-promscrape.cluster.replicationFactor` command-line flag. See [these docs](https://victoriametrics.github.io/vmagent.html#scraping-big-number-of-targets). * FATURE: vmagent: accept `scrape_offset` option at `scrape_config`. This option may be useful when scrapes must start at the specified offset of every scrape interval. See [these docs](https://victoriametrics.github.io/vmagent.html#troubleshooting) for details. * FEATURE: vmauth: allow using regexp paths in `url_map`. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1112) for details. + * BUGFIX: vmagent: prevent from high CPU usage bug during failing scrapes with small `scrape_timeout` (less than a few seconds). * BUGFIX: vmagent: reduce memory usage when Kubernetes service discovery is used in big number of distinct jobs by sharing the cache. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1113 * BUGFUX: avoid `duplicate time series` error if `prometheus_buckets()` covers a time range with distinct set of buckets.
