存储适配器

ChunkFlow 通过适配器支持多种存储后端。

可用适配器

LocalStorageAdapter

在本地文件系统上存储分片。

const storage = new LocalStorageAdapter("./storage");

OSSStorageAdapter

在阿里云 OSS 上存储分片。

const storage = new OSSStorageAdapter({
  region: "oss-cn-hangzhou",
  accessKeyId: "your-key",
  accessKeySecret: "your-secret",
  bucket: "your-bucket",
});

自定义适配器

实现 StorageAdapter 接口：

interface StorageAdapter {
  saveChunk(chunkHash: string, data: Buffer): Promise<void>;
  getChunk(chunkHash: string): Promise<Buffer>;
  chunkExists(chunkHash: string): Promise<boolean>;
  chunksExist(chunkHashes: string[]): Promise<boolean[]>;
  getChunkStream(chunkHash: string): Promise<ReadableStream>;
}
