## Batch Jobs Terminology

### Job
A job is the basic unit of work for MinIO Batch Job. A job is a self describing YAML, once this YAML is submitted and evaluated - MinIO performs the requested actions on each of the objects obtained under the described criteria in job YAML file.

### Type

The MinIO server requires an available KMS to en/decrypt SSE-S3 encrypted objects. Therefore it is possible to erase or lock some or all encrypted objects. For example in case of a detected attack or other emergency situations the following actions can be taken:

```

Description of the configuration parameters used above -

- `policies[].name` - name of the policy to create, must be a string with length > 0
- `policies[].statements[]` - list of statements, includes actions and resources

```sh
tar xvfz prometheus-*.tar.gz
cd prometheus-*
```

Prometheus server is a single binary called `prometheus` (or `prometheus.exe` on Microsoft Windows). Run the binary and pass `--help` flag to see available options

```sh
./prometheus --help
usage: prometheus [<flags>]

The Prometheus monitoring server

```

    // Due to current generics limitations, a constructor of the empty type must be provided.
    instance := grid.NewStream[*Payload, *Req, *Resp](h, newPayload, newReq, newResp)
	
    // Tweakable options
    instance.WithPayload = true // default true when newPayload != nil
    instance.OutCapacity = 1    // default
    instance.InCapacity = 1     // default true when newReq != nil
	

## MinIO Deployment on Kubernetes

There are multiple options to deploy MinIO on Kubernetes:

metadata                                                                                                                                                                       100%  226    16.6KB/s   00:00

```

## Advanced options

### Change default FTP port

Default port '8021' can be changed via

```
--ftp="address=:3021"
```

### Change FTP passive port range

- For Veeam Backup with Immutability, you can choose a number of restore points or days to make backups immutable.

## Publish MinIO events via PostgreSQL

> NOTE: Until release RELEASE.2020-04-10T03-34-42Z PostgreSQL notification used to support following options:
>
> ```
> host                (hostname)           Postgres server hostname (used only if `connection_string` is empty)

Let's take for example a set of 12 compute nodes with an aggregate memory of _1.2TiB_, we need to do following settings for optimal results. Add the following optimal entries for _core-site.xml_ to configure _s3a_ with **MinIO**. Most important options here are

```
cat ${HADOOP_CONF_DIR}/core-site.xml | kv-pairify | grep "mapred"

mapred.maxthreads.generate.mapoutput=2 # Num threads to write map outputs
mapred.maxthreads.partition.closer=0 # Asynchronous map flushers
