VictoriaMetrics/VictoriaMetrics v1.41.0 on GitHub

Changes since v1.40.1

FEATURE: reuse timestamp blocks for adjancent metric blocks with identical timestamps. This reduces disk space usage when scraping targets containing metrics with identical names such as node_cpu_seconds_total, histograms, quantiles, etc. Important: this changes on-disk data format. This makes impossible downgrading to releases below v1.41.0. These releases may panic with the following error after downgrading:
```
       cannot read next block: invalid TimestampsBlockOffset at block header at offset ...
```
FEATURE: initial implementation of Graphite Metrics API - see these docs.
FEATURE: vmagent: add endpointslices discovery type to kubernetes_sd_config. This is similar to prometheus/prometheus#6838 , which has been added in Prometheus v2.21. See https://github.com/prometheus/prometheus/releases/tag/v2.21.0
FEATURE: vmagent: add __meta_dns_srv_record_target and __meta_dns_srv_record_port labels to dns_sd_config. This syncs dns service discovery with Prometheus 2.21 - see https://github.com/prometheus/prometheus/releases/tag/v2.21.0 and prometheus/prometheus#7678
FEATURE: vmagent: allow setting multiple identical -remoteWrite.url values. This may be useful when each url is authenticated via different -remoteWrite.basicAuth.username. See #755
FEATURE: vmalert: update groups on config reload only if changes detected. This should speed up config reload for big number of groups when only a small part of these groups are updated. See #691
FEATURE: vmalert: add Group name as label to generated alerts and timeseries. See #611
FEATURE: support composite durations like Prometheus 2.21 does. The following durations are supported now: 1h5m35s or 1s543ms. See https://github.com/prometheus/prometheus/releases/tag/v2.21.0 and prometheus/prometheus#7713
FEATURE: add a jitter to -http.connTimeout in order to protect from Thundering herd problem when many connections are re-established at the same time.
FEATURE: allow passing timestamp via timestamp query arg when ingesting data at /api/v1/import/prometheus. See these docs. See #750
FEATURE: update Go builder from v1.15.1 to v1.15.2. This fixes the following issues in Go runtime: https://github.com/golang/go/issues?q=milestone%3AGo1.15.2+label%3ACherryPickApproved
BUGFIX: vmagent: do not reset the remaining rows when pushing a part of data to remote storage during big scrapes. See #753
BUGFIX: vmbackup, vmrestore: do not set AWS config profile to default by default, since it may break default AWS auth mechanism. See #726
BUGFIX: do not store inf values, since they may lead to significant precision loss for previously stored values. See #752
BUGFIX: skip infinite values when calculating smooth_exponential() function from MetricsQL. This should help with missing results in ttf() function. See #757
BUGFIX: adjust integrate() calculations to be more similar to calculations from InfluxDB. See #701
