Hi all, is Minio S3 supported as a blob storage for saving checkpoints?

Hi @René Yes it is. You would need to configure the following fields if memory serves me right (it's been awhile since I tried it) In your Flink config s3.endpoint (Minio Endpoint) s3.path.style.access s3.access-key s3.secret-key Then set your checkpoint directory using s3 path. Please see the docs here for more info: https://nightlies.apache.org/flink/flink-docs-release-1.20/docs/deployment/filesystems/s3/#configure-non-s3-endpoint
