createFileSystemS3MultipartResumeStore

function createFileSystemS3MultipartResumeStore(options: FileSystemS3MultipartResumeStoreOptions): S3MultipartResumeStore;

Defined in: src/providers/web/S3Provider.ts:188

File-system backed S3MultipartResumeStore that survives process restarts. Each in-flight multipart upload is checkpointed to a single JSON file in options.directory after every part. On retry the upload reuses the stored uploadId and skips parts that S3 has already accepted.

The implementation writes atomically (<file>.tmp then rename) so a crash mid-write cannot leave a corrupt checkpoint.

Parameters

Parameter	Type
options	FileSystemS3MultipartResumeStoreOptions

Returns

S3MultipartResumeStore

Example

import { createFileSystemS3MultipartResumeStore, createS3ProviderFactory }
  from "@zero-transfer/sdk";

const resumeStore = createFileSystemS3MultipartResumeStore({
  directory: "./.zt-s3-resume",
});

const factory = createS3ProviderFactory({
  multipart: { enabled: true, resumeStore },
});
