Yandex Object Storage is an S3-compatible object storage service from Yandex Cloud for storing and retrieving any amount of data at any time. It supports standard S3 API operations including upload, download, and listing objects.
With the Yandex Object Storage integration in AACFlow, you can:
- Upload Object: Store files and data to a bucket with a specified key/path
- Download Object: Retrieve files and objects from a bucket by key
- List Objects: Enumerate objects in a bucket with optional prefix filtering
This integration enables file storage, data pipeline workflows, and cloud-based document management for applications running on Yandex Cloud.
Usage Instructions
Integrate Yandex Object Storage into the workflow to manage files in your buckets. Requires an Access Key ID and Secret Access Key from your Yandex Cloud service account. Create service account keys in the Yandex Cloud console under IAM → Service Accounts.
