NOTE: in lazySeriesSet in theory we could just panic, I think however we can totally just return error, it will panic in expand anyway.

Load only some offsets into the symbol table into memory. Rather than keeping the entire symbol table in memory, keep every nth offset and walk from there to the entry we need. This ends up slightly slower, ~360ms per 1M series returned from PostingsForMatchers which is not much considering the rest of the CPU such a query would go on to use. Make LabelValues use the postings tables, rather than having to do symbol lookups. Use yoloString, as PostingsForMatchers doesn't need the strings to stick around and adjust the API call to keep the Querier open until it's all marshalled. Remove allocatedSymbols memory optimisation, we no longer keep all the symbol strings in heap memory. Remove LabelValuesFor and LabelIndices, they're dead code. Ensure we've still tests for label indices, and add missing test that we can work with old V1 Format index files. PostingForMatchers performance is slightly better, with a big drop in allocation counts due to using yoloString for LabelValues: benchmark old ns/op new ns/op delta

Load only some offsets into the symbol table into memory. Rather than keeping the entire symbol table in memory, keep every nth offset and walk from there to the entry we need. This ends up slightly slower, ~360ms per 1M series returned from PostingsForMatchers which is not much considering the rest of the CPU such a query would go on to use. Make LabelValues use the postings tables, rather than having to do symbol lookups. Use yoloString, as PostingsForMatchers doesn't need the strings to stick around and adjust the API call to keep the Querier open until it's all marshalled. Remove allocatedSymbols memory optimisation, we no longer keep all the symbol strings in heap memory. Remove LabelValuesFor and LabelIndices, they're dead code. Ensure we've still tests for label indices, and add missing test that we can work with old V1 Format index files. PostingForMatchers performance is slightly better, with a big drop in allocation counts due to using yoloString for LabelValues: benchmark old ns/op new ns/op delta

Load only some offsets into the symbol table into memory. Rather than keeping the entire symbol table in memory, keep every nth offset and walk from there to the entry we need. This ends up slightly slower, ~360ms per 1M series returned from PostingsForMatchers which is not much considering the rest of the CPU such a query would go on to use. Make LabelValues use the postings tables, rather than having to do symbol lookups. Use yoloString, as PostingsForMatchers doesn't need the strings to stick around and adjust the API call to keep the Querier open until it's all marshalled. Remove allocatedSymbols memory optimisation, we no longer keep all the symbol strings in heap memory. Remove LabelValuesFor and LabelIndices, they're dead code. Ensure we've still tests for label indices, and add missing test that we can work with old V1 Format index files. PostingForMatchers performance is slightly better, with a big drop in allocation counts due to using yoloString for LabelValues: benchmark old ns/op new ns/op delta

tsdb: Added ChunkQueryable implementations to db; unified MergeSeriesSets and vertical to single struct. (#7069) * tsdb: Added ChunkQueryable implementations to db; unified compactor, querier and fanout block iterating. Chained to https://github.com/prometheus/prometheus/pull/7059 * NewMerge(Chunk)Querier now takies multiple primaries allowing tsdb DB code to use it. * Added single SeriesEntry / ChunkEntry for all series implementations. * Unified all vertical, and non vertical for compact and querying to single merge series / chunk sets by reusing VerticalSeriesMergeFunc for overlapping algorithm (same logic as before) * Added block (Base/Chunk/)Querier for block querying. We then use populateAndTomb(Base/Chunk/) to iterate over chunks or samples. * Refactored endpoint tests and querier tests to include subtests.
