* tsdb: Unit test query overlapping in order and ooo head Signed-off-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> * TSDB: Merge overlapping head chunk The basic idea is that getOOOSeriesChunks can populate Meta.Chunk, but since it only returns one Meta per overlapping time-slot, that pointer may end up in a Meta with a head-chunk ID. So we need HeadAndOOOChunkReader.ChunkOrIterable() to call mergedChunks in that case. Previously, mergedChunks was checking that meta.Ref was a valid OOO chunk reference, but it never actually uses that reference; it just finds all chunks overlapping in time. So we can delete that code. Signed-off-by: Bryan Boreham <bjboreham@gmail.com> Co-authored-by: György Krajcsovits <gyorgy.krajcsovits@grafana.com> |
