What it is and what it does

ibm-cos-sdk-s3transfer is a Python library for transferring data to and from IBM Cloud Object Storage using an S3-compatible API. It wraps the lower-level ibm-cos-sdk-core dependency to provide a higher-level transfer manager interface.

The package is in abandoned maintenance: the repository is archived, the last commit was 2026-04-14, and it is marked as Development Status Alpha. It will not receive updates, security patches, or bug fixes. If you depend on IBM COS transfers, you should verify whether IBM provides an actively maintained alternative or whether ibm-cos-sdk-core is still supported.

Use it for:

Transfer large files to IBM COS with automatic multipart handling.
Download objects from IBM COS in a managed way.
Integrate IBM COS storage into data pipeline or backup workflows.
Migrate data between local storage and IBM Cloud Object Storage.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Manages transfers to and from IBM Cloud Object Storage using an S3-compatible interface, handling upload, download, and multipart operations.

No. The package is abandoned (no commits since 2026-04-14, archived repository) and will not receive maintenance or security updates. High install friction from a compiled dependency compounds the risk. Use only if locked into an existing deployment and unable to migrate to an actively maintained alternative.

Installing ibm-cos-sdk-s3transfer

Before you install

High install friction due to a compiled dependency (ibm-cos-sdk-core). The package is abandoned with no commits since 2026-04-14 and an archived repository; it will not receive updates or security patches.

License in practice

Licensed under Apache License 2.0 (permissive), allowing commercial and private use with minimal restrictions, though you assume responsibility for issues since the project is no longer maintained.

Quickstart

pip install ibm-cos-sdk-s3transfer

from ibm_cos_sdk_s3transfer import S3Transfer

transfer = S3Transfer(client)

Requires ibm-cos-sdk-core, a compiled dependency that may require build tools; Python 3.8 or later.
