---------------------------------

             Summary: Do not cross-compact unseq files when there are 
non-compacted old unseq files
                 Key: IOTDB-1398
                 URL: https://issues.apache.org/jira/browse/IOTDB-1398
             Project: Apache IoTDB
          Issue Type: Bug
          Components: Compaction
            Reporter: Tian Jiang
            Assignee: Tian Jiang
             Fix For: 0.13.0


Current file selection for cross compaction (involving both seq files and unseq 
files) may choose unseq files and skip some older files, resulting in 
over-written data reappear.

The selection should be terminated once an unfeasible unseq file is detected, 
which should be left for future compaction.
