- Remove unrelated changes - Refactor code out of the API module - that is already getting pretty crowded. - Don't track reference for AddFast in remote write. This has the potential to consume unlimited server-side memory if a malicious client pushes a different label set for every series. For now, its easier and safer to always use the 'slow' path. - Return 400 on out of order samples. - Use remote.DecodeWriteRequest in the remote write adapters. - Put this behing the 'remote-write-server' feature flag - Add some (very) basic docs. - Used named return & add test for commit error propagation Signed-off-by: Tom Wilkie <tom.wilkie@gmail.com>

# 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](https://github.com/prometheus/prometheus/blob/master/CHANGELOG.md).
|
||
|
||
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`
|
||
|
||
This feature lets you specify the evaluation time for instant vector selectors,
|
||
range vector selectors, and subqueries. More details can be found [here](querying/basics.md#@-modifier).
|
||
|
||
## Remote Write Receiver
|
||
|
||
`--enable-feature=remote-write-receiver`
|
