This can be useful in the following queries:
drop_empty_series(temperature <= 30) default 40
This query drops temperature series with all the values bigger than 30 on the selected time range,
while replacing gaps in the remaining series with 40.
The query without drop_empty_series:
(temperature <= 30) default 40
would leave all the temperature series with all the values bigger than 30 on the selected time range,
and replace all their values with 40. This is not what could be epxected in some cases

This reverts commit 3d7a77bf82.
Reason for revert: relative links do not work properly at GitHub code
and at GitHub wiki. For example, the following page contains broken links
before reverting this commit:
https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/docs/VictoriaLogs/CHANGELOG.md
It is always better to use absolute links thank relative links, since the page contents
can be copy-n-pasted to other pages, which are located in vastly different directories,
and all the links will remain working.
* fixed error when creating a full backup using the `-origin` flag (#5144)

This is a follow-up for f60c08a7bd
Changes:
- Make sure all the urls related to NewRelic protocol start from /newrelic . Previously some urls were started from /api/v1/newrelic
- Remove /api/v1 part from NewRelic urls, since it has no sense
- Remove automatic transformation from CamelCase to snake_case for NewRelic labels and metric names,
since it may complicate the transition from NewRelic to VictoriaMetrics. Preserve all the metric names and label names,
so users could query metrics and labels by the same names which are used in NewRelic.
The automatic transformation from CamelCase to snake_case can be added later as a special action for relabeling rules if needed.
- Properly update per-tenant data ingestion stats at app/vmagent/newrelic/request_handler.go . Previously it was always zero.
- Fix NewRelic urls in vmagent when multitenant data ingestion is enabled. Previously they were mistakenly started from `/`.
- Document NewRelic data ingestion url at docs/Cluster-VictoriaMetrics.md
- Remove superflouos memory allocations at lib/protoparser/newrelic
- Improve tests at lib/protoparser/newrelic/*
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3520
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4712
- Make more clear the docs at docs/enterprise.md, so readers could figure out faster
on how to obtain enterprise key and how to pass it to VictoriaMetrics Enterprise components.
- Fix examples at docs/enterprise.md, which were referring to non-existing `-license-file` command-line flag.
The `-licenseFile` command-line flag must be used instead.
- Improve the description of `-license*` command-line flags, so users could understand
faster how to use them.
- Improve the warning message, which is emitted when the deprecated -eula command-line flag is passed,
so the user could figure out how to switch faster to -license* command-line flags.
- Disallow running VictoriaMetrics components with both -license and -licenseFile command-line flags.
- Disallow running VictoriaMetrics components when -licensFile points to an empty file.
- Consistently use the phrase "This flag is available only in Enterprise binaries" across
all the enterprise-specific command-line flags.
- Remove unneeded level of indirection for `noLicenseMessage` and `expiredMessage` string contants
in order to improve code readability and maintainability.
- Remove unneded `return` statements after `logger.Fatalf()` calls, since these calls exit the app and never return.
- Make sure that the info log message about successful license verification is emitted
when the license is verified successfully. Previously the error message could be logged
when the license payload is invalid or if it misses some required features.
This reverts commit a8345bb1b9
Reason for revert: VictoriaMetrics binaries are consistently created inside `bin` directory at the root of the repository
when running `make <vm-app>` according to https://docs.victoriametrics.com/#how-to-build-from-sources
If some dev environments create binaries inside random directories, then it is better to provide docs
at https://docs.victoriametrics.com/#how-to-build-from-sources on how to setup these IDEs, so they
consistently create binaries at bin/* directory at the root of the repository instead of trying to add
random ignore rules inside .gitignore.
As for the data directories created by VictoriaMetrics components, they may be created at random places too,
so there is little sense in trying to add ignore rules for all these directories inside .gitignore.
It is better to document that the built binaries must be consistently started from the repository root,
so data directories are created at the repository root. The .gitignore already contains rule
for blocking common data directories, which can be created by VictoriaMetrics components at the repository root.
- Reduce vertical space usage, so more information is available on the screen without the need to scroll.
- Show information for lines with higher values at the top of the legend under the graph.
This should simplify graph analysis when it contains many lines.
Fix vminsert/vmstorage/vmselect metrics filtering when dashboard is used
to display data from many sub-clusters with unique job names.
Before, only one specific job could have been accounted for component-specific panels,
instead of all available jobs for the component.

reduce lock contention for heavy aggregation requests
previously lock contetion may happen on machine with big number of CPU due to enabled string interning. sync.Map was a choke point for all aggregation requests.
Now instead of interning, new string is created. It may increase CPU and memory usage for some cases.
