Disabled Features
Here is a list of features that are disabled by default since they are breaking changes or are considered experimental. Their behaviour can change in future releases which will be communicated via the release changelog.
You can enable them using the --enable-feature flag with a comma separated list of features.
They may be enabled by default in future versions.
@ Modifier in PromQL
--enable-feature=promql-at-modifier
The @ modifier lets you specify the evaluation time for instant vector selectors,
range vector selectors, and subqueries. More details can be found here.
Negative offset in PromQL
--enable-feature=promql-negative-offset
In contrast to the positive offset modifier, the negative offset modifier lets one shift a vector into the future. An example in which one may want to use a negative offset is reviewing past data and making temporal comparisons with more recent data.
More details can be found here.
## Remote Write Receiver
--enable-feature=remote-write-receiver
The remote write receiver allows Prometheus to accept remote write requests from other Prometheus servers. More details can be found here.
