> For each data file TsFile, we generate a TsFileResource, which contains the time interval of paths in this file.  The TsFileResource is used as a time filter to locate data.
> Currently, all TsFileResources are cached in memory (TsFileManagement.java).
> This may cause OOM. We need to control its memory.
