## Description Now, we will create QueryDataSource for each sensor in one query. QueryDataSource contains two file lists, one for seq files and another one for unseq files. This means, if we have 90,000 files and 1,000 sensors in one query, we will occupy 90,000 * 1,000 * 24B(about 2GB memory footprint) which will cause OOM problems. However, we can let all sensors in one virtual sg share the same QueryDataSource, and save its own seq and unseq cursor in SeriesReader. -- This is an automated message from the Apache Git Service.
