Realtime Compute for Apache Flink:Artifacts

Last Updated:Aug 06, 2026

When you create a workspace, Realtime Compute for Apache Flink creates several directories in the Object Storage Service (OSS) bucket that you provide. These directories store files used or created by your Flink jobs, including checkpoints, savepoints, logs, and JAR packages. This topic describes these directories and explains how to manage your artifacts.

OSS bucket

Directory contents

If you select an OSS bucket as your storage type, Realtime Compute for Apache Flink creates the following directories in that bucket.

Directory

Contents

artifacts

Stores uploaded JAR packages, additional dependencies, and Python files and their dependencies.

sql-artifacts

Stores files required by registered user-defined functions and connectors.

flink-jobs

Stores high availability (HA) information and checkpoint data for Flink jobs.

flink-savepoints

Stores savepoint files generated when you click Create Savepoint in the Flink console.

flink-sessionclusters

Stores high availability (HA) information and checkpoint data for session clusters.

plan

Stores resource configuration information when you use expert mode.

logs

Stores job logs if you configure your job to output logs to OSS.

Manage artifacts

When using an OSS bucket, you can only upload, download, and delete files in the artifacts directory from the Flink console.

  1. Log on to the Realtime Compute for Apache Flink console.

  2. In the Actions column for the target workspace, click Console.

  3. In the Object Storage Service (OSS) console, configure a cross-origin resource sharing (CORS) rule for the OSS bucket associated with your workspace.

    If a cross-origin resource sharing (CORS) rule is not configured, file uploads may fail due to cross-origin restrictions. When you configure the CORS rule, set the Origin to https://vvpsg.console.alibabacloud.com, allow all Methods (select all), and set the Allowed Headers to *.

  4. In the left-side navigation pane, click Artifacts. You can perform the following operations.

    Actions

    Description

    Upload Artifact

    Click Upload Artifact and select a local file, or drag the file directly into the artifact list area.

    After the upload, the file path is oss://<Your bound OSS Bucket name>/artifacts/namespaces/<Project name>/<File name>. You can click the file name to copy the path.

    For more information about the project name, see View and delete a project.

    Download Artifact

    In the Actions column, click Download to save the artifact to your local machine.

    Delete Artifact

    In the Actions column, click Delete to permanently remove the artifact from the OSS bucket.

Transfer acceleration

If you experience slow uploads or downloads of large files over long distances, you can enable transfer acceleration. To enable it, turn on the Transfer Acceleration switch in the upper-right corner of the page.

Note

To use this feature, you must first enable transfer acceleration for your OSS bucket. Enabling this feature incurs additional data transfer costs. For more information about billing, see Transfer acceleration fees.
