Björn Rabenstein	d677aa4b29	storage: Consolidate iterator method names (Values -> At) (#9888 ) `BufferedSeriesIterator` and `MemoizedSeriesIterator` use a method called `Values` for exactly the purpose for which all other iterators of the same kind use a method called `At`. That alone is confusing, but on top of that, the `Values` method only returns a single sample, not multiple values. I assume the naming has historical reasons. This commit makes it more consistent. It is now easier to read, and now `BufferedSeriesIterator` and `MemoizedSeriesIterator` implement `chunkenc.Iterator` like many other iterators, too.

Ganesh Vernekar	2a3d62ac84	Revert "promql: Remove unused Point.MarshalJSON method (#9860 )" (#9864 ) This reverts commit `427425cc9f`. Signed-off-by: Ganesh Vernekar <ganeshvern@gmail.com>	3 years ago
Björn Rabenstein	427425cc9f	promql: Remove unused Point.MarshalJSON method (#9860 ) JSON marshaling is only needed for the HTTP API. Since Point is such a frequently marshaled type, it gets an optimized treatment directly in web/api/v1/api.go. The MarshalJSON method still provided in the promql package is therefore unused and its existence is confusing. Signed-off-by: beorn7 <beorn@grafana.com>	3 years ago

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.
