Bryan Boreham	3da2c99ffd	tsdb/index: don't call ExpandPostings in a benchmark This allocates memory for all the returned values, which skews the result. We aren't trying to benchmark `ExpandPostings`, so just step through all the values without storing them to consume them. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	2 years ago

Oleg Zaytsev	701545286d	Pop intersected postings heap without popping (#10092 ) See this comment for detailed explanation: https://github.com/prometheus/prometheus/pull/9907#issuecomment-1002189932 TL;DR: if we don't call Pop() on the heap implementation, we don't need to return our param as an `interface{}` so we save an allocation. This would be popped for every label value, so it can be thousands of saved allocations here (see benchmarks). Signed-off-by: Oleg Zaytsev <mail@olegzaytsev.com>	3 years ago

This avoid expanding postings (and thus having all of them in memory at any point). Slightly slower than the expanding postings version for some cases, but definitely pays the price once the cardinality grows. Still offers 10x latency improvement where previous latencies were reaching 1s.

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.

Bryan Boreham	9dfdc3eb36	Speed up BenchmarkPostings_Stats (#9213 ) The previous code re-used series IDs 1-1000 many times over, so a lot of time was spent ensuring the lists of series were in ascending order. The intended use of `MemPostings.Add()` is that all series IDs are unique, and changing the benchmark to do this lets it finish ten times faster.
