Thanks Lingzhe for propose this problem. Data correctness is indeed a very important issue. If the accuracy of data can not be guaranteed, the impact on the business is unknown. In the previous versions, we lost data several times before, which also exposed the defects of our test. Bugs are inevitable, but if there is data loss? Can we have other plans to get the data back?

Because of this bug, we will release 0.12.2 and 0.11.5 soon. Before new version released, we can set the parameter enable_unseq_compaction in conf/iotdb-engine.properties to false. In this way, we can disable cross space compaction and avoid this bug.
