Hi,
I meet a scenario that one device has 300k measurements. When we read one time series in a TsFile, we need to deserialize 300k TimeseriesMetadata, which costs about 250ms (just for reading metadata of one tsfile). This may cause the query much slow. As this scenario is not rare, I think this should be optimized by adding more indexes in TsFileMetadata. Thanks, -- Jialin Qiao School of Software, Tsinghua University 乔嘉林 清华大学 软件学院
