Dieter Plaetinck	0fac9bb859	Add basic initial developer docs for TSDB (#9451 ) * Add basic initial developer docs for TSDB There's a decent amount of content already out there (blog posts, conference talks, etc), but: * when they get stale, they don't tend to get updated * they still leave me with questions that I'ld like to answer for developers (like me) who want to use, or work with, TSDB What I propose is developer docs inside the prometheus repository. Easy to find and harness the power of the community to expand it and keep it up to date. * perfect is the enemy of good. Let's have a base and incrementally improve * Markdown docs should be broad but not too deep. Source code comments can complement them, and are the ideal place for implementation details.

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. TODO: Implement BlockSeriesRef where appropriate (for a future PR) Signed-off-by: Dieter Plaetinck <dieter@grafana.com> * feedback Signed-off-by: Dieter Plaetinck <dieter@grafana.com> * agent: demistify seriesRefs and ChunkRefs Signed-off-by: Dieter Plaetinck <dieter@grafana.com>	3 years ago
