### Search before asking - [X] I searched in the [issues](https://github.com/apache/iotdb/issues) and found nothing similar. ### Version Centos 7.4 0.13.4 ### Describe the bug and provide the minimal reproduce step After migrating data from another iotdb instance to the new one, there are a lot of files in unsequence folder, and the total file size is about 11G, meanwhile, the query performance is very poor for some query sql, which takes about 80+ seconds to finish the query. ### What did you expect to see? the file size in unsequence folder decrease after run MERGE command in CLI and the query cost should be under 1s. ### What did you see instead? nothing happen after running the MERGE command. ### Anything else? _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
