- Source location from where the objects must be copied from
- Target location from where the objects must be copied to
- Fine grained filtering is available to pick relevant objects from source to copy from

MinIO batch jobs framework also provides

- Retrying a failed job automatically driven by user input
- Monitoring job progress in real-time

Each process, or "runtime", applies different constraints to the code that runs in that process.
For example, each process has different supported JVMs and a different set of services available for dependency injection.
While a lot of Gradle source code runs only in the Gradle daemon, not all of it does and so, when working on some source code it is important to be aware of the runtimes in which it will run.

#### 3.2.a Automatic removal of noncurrent versions keeping only most recent ones immediately (MinIO only extension)

This is available only on MinIO as an extension to the NewerNoncurrentVersions feature. The following rule makes it possible to remove older noncurrent versions

#### Common information available in all requests

- `aws:CurrentTime` - This can be used for conditions that check the date and time.
- `aws:EpochTime` - This is the date in epoch or Unix time, for use with date/time conditions.

> NOTE: A zero value of `requests_max` means MinIO will automatically calculate requests based on available RAM size and that is the default behavior.

### Configuring connection (wait) deadline

This value works in conjunction with max connection setting, setting this value allows for long waiting requests to quickly time out when there is no slot available to perform the request.

```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>]
