[GitHub] [doris] BePPPower opened a new issue, #15456: [Enhancement](file reader) Refactor file reader
BePPPower opened a new issue, #15456:
URL: https://github.com/apache/doris/issues/15456
### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues.
### Description
Currently, there are two sets of file readers in Doris. We need to integrate the old file reader into the new file reader.
The purposes of the new file reader are:
1. Simplifies the file reader interface, and abstracts the file system to facilitate access to different storage media.
Accessing different storage media will have different file systems (except `streamLoadPipe`), and file readers are
generated from corresponding file system。
2. Prepare for the introduction of File Cache in the future.
We will import file cache for accessing `RemoteFileSystem` (such as HdfsFileSystem and S3FileSystem), and the logic of the file cache will be hidden inside the file reader so that for the upper-layer caller, the change of the file cache does not need to modify the upper-layer calling logic
