MinIO RELEASE.2022-10-08T20-11-00Z
The Batch Framework was introduced with the replicate
job type in the mc
RELEASES.2022-10-08T20-11-00Z.
Overview
The MinIO Batch Framework allows you to create, manage, monitor, and
execute jobs using a YAML-formatted job definition file (a "batch
file"). The batch jobs run directly on the MinIO deployment to take
advantage of the server-side processing power without constraints of the
local machine where you run the MinIO Client <minio-client>
.
A batch file defines one job task.
Once started, MinIO starts processing the job. Time to completion depends on the resources available to the deployment.
If any portion of the job fails, MinIO retries the job up to the number of times defined in the job definition.
The MinIO Batch Framework supports the following job types:
Job Type | Description |
---|---|
replicate |
Perform a one-time replication procedure from one MinIO location to another MinIO location. |
keyrotate |
Perform a one-time process to cycle the sse-s3 or sse-kms <minio-sse-data-encryption>
cryptographic keys on objects. |
MinIO Batch CLI
- Install the
MinIO Client <minio-client>
- Define an
alias <mc alias set>
for the MinIO deployment
The mc batch
commands
include
mc batch generate |
|
mc batch start |
|
mc batch list |
|
mc batch status |
|
mc batch describe |
Access to mc batch
You can use MinIO's Policy Based Access Control <minio-policy>
and
the administrative policy actions <minio-policy-mc-admin-actions>
to restrict who can start a batch job, retrieve a list of running jobs,
or describe a running job.
Job Types
Replicate
Use the replicate
job type to create a batch job that
replicates objects from one MinIO deployment to another MinIO
target.
MinIO Server RELEASE.2023-05-04T21-44-30Z
replicate
batch jobs also support mc mirror
-like behavior when
presented an S3-compatible source or target.
At least one of the deployment locations, either the source or the
target, must be local
. The definition file can limit the
replication by bucket, prefix, and/or filters to only replicate certain
objects.
MinIO Server RELEASE.2023-04-07T05-28-58Z
You can replicate from a remote MinIO deployment to the local deployment that runs the batch job.
For example, you can use a batch job to perform a one-time
replication sync to push objects from a bucket on a local deployment at
minio-local/invoices/
to a bucket on a remote deployment at
minio-remote/invoices
. You can also pull objects from the
remote deployment at minio-remote/invoices
to the local
deployment at minio-local/invoices
.
The advantages of Batch Replication over mc mirror
include:
- Removes the client to cluster network as a potential bottleneck
- A user only needs access to starting a batch job with no other permissions, as the job runs entirely server side on the cluster
- The job provides for retry attempts in event that objects do not replicate
- Batch jobs are one-time, curated processes allowing for fine control replication
- (MinIO to MinIO only) The replication process copies object versions from source to target
MinIO Server RELEASE.2023-02-17T17-52-43Z
Run batch replication with multiple workers in parallel by specifying
the MINIO_BATCH_REPLICATION_WORKERS
environment
variable.

Key Rotate
MinIO RELEASE.2023-04-07T05-28-58Z
Use the keyrotate
job type to create a batch job that
cycles the sse-s3 or sse-kms keys <minio-sse-data-encryption>
for encrypted objects.
The YAML configuration supports filters to restrict key rotation to a specific set of objects by creation date, tags, metadata, or kms key. You can also define retry attempts or set a notification endpoint and token.
