## File Rotation / 文件轮转
|
||||
|
||||
- basic rotation is size-based / 当前基础轮转为按文件大小触发
|
||||
- `file_rotation(max_bytes, max_backups=...)` controls threshold and retained backups / `file_rotation(max_bytes, max_backups=...)` 控制触发阈值和保留备份数
|
||||
- JSON config uses `sink.rotation.max_bytes` and `sink.rotation.max_backups` / JSON 配置使用 `sink.rotation.max_bytes` 与 `sink.rotation.max_backups`
