Combine Appender.Add and AddFast into a single Append method. (#8489) 
This moves the label lookup into TSDB, whilst still keeping the cached-ref optimisation for repeated Appends.

This makes the API easier to consume and implement.  In particular this change is motivated by the scrape-time-aggregation work, which I don't think is possible to implement without it as it needs access to label values.

always pass with empty exp_alerts, and never with non-empty exp_alerts.

Tom Wilkie d479151f1f Various enhancements and refactorings for remote write receiver: 
- 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

Merge pull request #8432 from roidelapluie/backfillpanic 
backfill: move checkErr before we close the mmaped file
 2021-02-03 16:32:35 +01:00
Julien Pivotto 9334269f2b backfill: move checkErr before we close the mmaped file 
When printing the error, we still need access to the mmapped byte array
of the file. Therefore, we make sure that we run it before closing the
file.

I could have done something more complex like a defer, or not closing
the file, knowing that we would exit the program anyway. However, I
think that in case we extend this in the future, or this is copy/paster
elsewhere, we should continue closing the file. As it is small enough, I
went for the solution to call the function 3 times instead of playing
with a defer.

'@ <timestamp>' modifier (#8121) 
This commit adds `@ <timestamp>` modifier as per this design doc: https://docs.google.com/document/d/1uSbD3T2beM-iX4-Hp7V074bzBRiRNlqUdcWP6JTDQSs/edit.

An example query:

```
rate(process_cpu_seconds_total[1m]) 
  and
topk(7, rate(process_cpu_seconds_total[1h] @ 1234))
```

which ranks based on last 1h rate and w.r.t. unix timestamp 1234 but actually plots the 1m rate.

Backfilling: fast-path for non-consecutive blocks (#8324) 
* Backfilling: optimize for non-consecutive blocks

When you have missing data for > 2 hours, you spend a lot of time
re-reading the complete file. It is not optimal.

This introduces a fastpath for this scenario.

Next, we do parse the metric even when we know we will not use it, based
on its timestamp. This only computes the metric when we know its
timestamp is right.
