Fields

access_key: Option<String>

The access key used to authenticate with the storage provider.

If not provided, rclone will fall back to environment-based credentials, such as RCLONE_S3_ACCESS_KEY_ID. In Kubernetes environments using IRSA (IAM Roles for Service Accounts), this can be left empty to allow automatic authentication via the pod’s service account.

bucket: String

The name of the storage bucket.

This may include a path to a folder inside the bucket (e.g., my-bucket/data).

checkers: Option<i64>

The number of checkers to run in parallel. Default: 20

endpoint: Option<String>

The endpoint URL for the storage service.

This is typically required for custom or local S3-compatible storage providers like MinIO. Example: http://localhost:9000

Relevant rclone config key: endpoint

fail_if_no_checkpoint: bool

When true, the pipeline will fail to initialize if fetching the specified checkpoint fails (missing, download error). When false, the pipeline will start from scratch instead.

False by default.

flags: Option<Vec<String>>

Extra flags to pass to rclone.

WARNING: Supplying incorrect or conflicting flags can break rclone. Use with caution.

Refer to the docs to see the supported flags:

• Global flags
• S3 specific flags

ignore_checksum: Option<bool>

Set to skip post copy check of checksums, and only check the file sizes. This can significantly improve the throughput. Defualt: false

multi_thread_cutoff: Option<String>

Use multi-thread download for files above this size. Format: [size][Suffix] (Example: 1G, 500M) Supported suffixes: k|M|G|T Default: 100M

multi_thread_streams: Option<i64>

Number of streams to use for multi-thread downloads. Default: 10

provider: Option<String>

The name of the cloud storage provider (e.g., "AWS", "Minio").

Used for provider-specific behavior in rclone. If omitted, defaults to "Other".

See rclone S3 provider documentation

pull_interval: i64

The interval (in seconds) between each attempt to fetch the latest checkpoint from object store while in standby mode.

Applies only when start_from_checkpoint is set to latest.

Default: 10 seconds

region: Option<String>

The region that this bucket is in.

Leave empty for Minio or the default region (us-east-1 for AWS).

retention_min_age: i64

The minimum age (in days) a checkpoint must reach before it becomes eligible for deletion. All younger checkpoints will be preserved.

Default: 30

retention_min_count: i64

The minimum number of checkpoints to retain in object store. No checkpoints will be deleted if the total count is below this threshold.

Default: 10

secret_key: Option<String>

The secret key used together with the access key for authentication.

If not provided, rclone will fall back to environment-based credentials, such as RCLONE_S3_SECRET_ACCESS_KEY. In Kubernetes environments using IRSA (IAM Roles for Service Accounts), this can be left empty to allow automatic authentication via the pod’s service account.

standby: bool

When true, the pipeline starts in standby mode; processing doesn’t start until activation (POST /activate). If this pipeline was previously activated and the storage has not been cleared, the pipeline will auto activate, no newer checkpoints will be fetched.

Standby behavior depends on start_from_checkpoint:

• If latest, pipeline continuously fetches the latest available checkpoint until activated.
• If checkpoint UUID, pipeline fetches this checkpoint once and waits in standby until activated.

Default: false

start_from_checkpoint: Option<StartFromCheckpoint>

transfers: Option<i64>

The number of file transfers to run in parallel. Default: 20

upload_concurrency: Option<i64>

The number of chunks of the same file that are uploaded for multipart uploads. Default: 10
