Dieter Plaetinck	cda025b5b5	TSDB: demistify SeriesRefs and ChunkRefs (#9536 ) * TSDB: demistify seriesRefs and ChunkRefs The TSDB package contains many types of series and chunk references, all shrouded in uint types. Often the same uint value may actually mean one of different types, in non-obvious ways. This PR aims to clarify the code and help navigating to relevant docs, usage, etc much quicker. Concretely: * Use appropriately named types and document their semantics and relations. * Make multiplexing and demuxing of types explicit (on the boundaries between concrete implementations and generic interfaces). * Casting between different types should be free. None of the changes should have any impact on how the code runs.

Tom Wilkie	7369561305	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.

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 Signed-off-by: Tom Wilkie <tom.wilkie@gmail.com>	4 years ago
