- 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
- Send notifications upon completion or failure to user configured target

Following YAML describes the structure of a replication job, each value is documented and self-describing.

        fmt.Println("Got result", resp)
        // Return the response for reuse
		instance.PutResponse(resp)
        return nil
    })
```

There are handlers for requests with:
 * No input stream: `RegisterNoInput`.
 * No initial payload: `RegisterNoPayload`.

Note that Responses sent for serialization are automatically reused for similar requests.

Add the following optimal entries for `hive-site.xml` to configure Hive with **MinIO**.

```
hive.blobstore.use.blobstore.as.scratchdir=true
hive.exec.input.listing.max.threads=50
hive.load.dynamic.partitions.thread=25
hive.metastore.fshandler.threads=50
hive.mv.files.threads=40
mapreduce.input.fileinputformat.list-status.num-threads=50
```

access to port 9000

```sh
iptables -A INPUT -p tcp --dport 9000 -j ACCEPT
service iptables restart
```

Below command enables all incoming traffic to ports ranging from 9000 to 9010.

```sh
iptables -A INPUT -p tcp --dport 9000:9010 -j ACCEPT
service iptables restart
```

## Test MinIO Connectivity

(*) Parquet is disabled on the MinIO server by default. See below how to enable it.

## Enabling Parquet Format

Parquet is DISABLED by default since hostile crafted input can easily crash the server.

If you are in a controlled environment where it is safe to assume no hostile content can be uploaded to your cluster you can safely enable Parquet.

		object_context = event["getObjectContext"]

		# Get the presigned URL to fetch the requested
		# original object from MinIO
		s3_url = object_context["inputS3Url"]

		# Extract the route and request token from the input context
		request_route = object_context["outputRoute"]
		request_token = object_context["outputToken"]

		# Get the original S3 object using the presigned URL
		r = requests.get(s3_url)

Such objects do not produce efficient [`LZ compression`](https://en.wikipedia.org/wiki/LZ77_and_LZ78)
which is a fitness factor for a lossless data compression.

Pre-compressed input typically compresses in excess of 2GiB/s per core,
so performance impact should be minimal even if precompressed data is re-compressed.
Decompressing incompressible data has no significant performance impact.

`xl-meta` accepts zip files as input and will output all `xl.meta` files found within the archive. For example:

```
$ mc support inspect play/test123/test*/xl.meta
mc: File data successfully downloaded as inspect.6f96b336.zip
$ xl-meta inspect.6f96b336.zip
