Description

Phenomenon

Cross compaction select one unseq file but cannot select any seq files.

 

After preliminary investigation, it is found that there are indeed a large number of unseq files which do not overlap with any seq files. There are two specific cases: 1. The devices under the unseq files do not exist in the seq files. 2. The device of the unseq file exists in the seq file, but unseqDevice.startTime>seqDevice.endTime.
