| `exclude_path` | Set one or multiple shell patterns separated by commas to exclude files matching certain criteria. For example, `exclude_path *.gz,*.zip`. | _none_ |
| `exit_on_eof` | When reading a file, exit as soon as it reaches the end of the file. Used for bulk load and tests. | `false` |
| `file_cache_advise` | Set the `posix_fadvise` in `POSIX_FADV_DONTNEED` mode. This reduces the usage of the kernel file cache. This option is ignored if not running on Linux. | `on` |

| `Unicode.Encoding` | Set the Unicode character encoding of the file data. This parameter requests two-byte aligned chunk and buffer sizes. If data isn't aligned for two bytes, Fluent Bit will use two-byte alignment automatically to avoid character breakages on consuming boundaries.
