Object Upload

In OBS, objects are basic data units that users can perform operations on. OBS Java SDK provides abundant APIs for object upload in the following methods:

  • Streaming upload
  • File-based upload
  • Multipart upload
  • Appendable Upload
  • Resumable upload

For steaming upload, appendable upload, and file-based upload, data to be uploaded at a time cannot be larger than 5 GB. If the file is larger than 5 GB, multipart upload (whose part size is smaller than 5 GB) is suitable.
