   > Can I append data to the file ?
   
   可以，可以使用`RestorableTsFileIOWriter` 实现追加写；
   Yes, you can use `RestorableTsFileIOWriter` to append data to an existed TsFile.
   
   > Can I modify data in a  TsFile?
   
   不行， TsFile不能做数据修改，这种情况下要么使用IoTDB，要么自己组织多个TsFile并用后者替代前者的数据。
   No, you can not modify data in a TsFile. If you need to modify data, use IoTDB interface, or you can manage several TsFiles and use the latter version to cover the previous versions.
