## How to enable Fan-Out Uploads ?

Fan-Out uploads are automatically enabled if `x-minio-fanout-list` form-field is provided with the PostUpload API, to keep things simple higher level APIs are provided in our SDKs for example in `minio-go` SDK:

```

  "z.a"(%arg0) : (f32) -> ()
  func.return %arg0 : f32
}
// CHECK: x.a
// CHECK: y.a
// CHECK: z.a
// CHECK: return
// CHECK-NOT: call
// CHECK: }

// -----

// CHECK-LABEL: @fanout
func.func @fanout(%arg0: f32) -> (f32) attributes {ignore_side_effects_for_testing} {
  %0 = "x.a"(%arg0) : (f32) -> (f32)
  %1 = "y.a"(%0) : (f32) -> (f32)
  %2 = "y.b"(%0) : (f32) -> (f32)
  %3 = "y.c"(%0) : (f32) -> (f32)

}

// Options are optional arguments to NewReaderWithOpts, Options
// simply converts positional arguments to NewReader() into a
// more flexible way to provide optional inputs. This is currently
// used by the FanOut API call mostly to disable expensive md5sum
// calculation repeatedly under hash.Reader.
type Options struct {
	MD5Hex     string
	SHA256Hex  string
	Size       int64
	ActualSize int64
	DisableMD5 bool

// Infer tensor shapes through abstract interpretation.
// If assume_valid_feeds is true, it can help infer shapes in the fanout of fed

MinIO supports all the exchanges available in [RabbitMQ](https://www.rabbitmq.com/). For this setup, we are using `fanout` exchange.

	// TODO these are used together to bucket items by namespace and then batch them up for processing.
	// The technique is valuable for rollup activities to avoid fanout and reduce resource contention.
	// We could move this into a library if another component needed it.
	// queue is indexed by namespace, so that we bundle up on a per-namespace basis
