...but continue reading below to see how to overcome that.

## Return Type and Data Filtering

Let's continue from the previous example. We wanted to **annotate the function with one type**, but we wanted to be able to return from the function something that actually includes **more data**.

                    });
                    // Remove duplicates (equal adjacent elements) - a new, un@Incubating type will be here twice, as 2 errors are reported; use stringified JSON to compare
                    // Filtering an array is NOT in place
                    result.acceptedApiChanges = result.acceptedApiChanges.filter((item, pos, ary) => (!pos || (JSON.stringify(item) != JSON.stringify(ary[pos - 1]))));
                    return result;

	"math"
	"math/bits"

// Mask allows filtering by a bitset mask.
type Mask uint64

const (
	// MaskAll is the mask for all entries.
	MaskAll Mask = math.MaxUint64
)

// MaskFromMaskable extracts mask from an interface.
func MaskFromMaskable(m Maskable) Mask {
	return Mask(m.Mask())
}

// Contains returns whether *all* flags in other is present in t.
func (t Mask) Contains(other Mask) bool {

- 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

    credentials:
      accessKey: minioadmin
      secretKey: minioadmin
    # sessionToken: SESSION-TOKEN # Optional only available when rotating credentials are used

  # NOTE: All flags are optional
  # - filtering criteria only applies for all source objects match the criteria
  # - configurable notification endpoints
  # - configurable retries for the job (each retry skips successfully previously replaced objects)

  # If "TPROXY", use iptables TPROXY to redirect to Envoy.
  # The "TPROXY" mode preserves both the source and destination IP
  # addresses and ports, so that they can be used for advanced filtering
  # and manipulation.
  # The "TPROXY" mode also configures the sidecar to run with the
  # CAP_NET_ADMIN capability, which is required to use TPROXY.

 * of project dependencies. This optimizes module loading during runtime, as we will only load external
 * modules that are not loaded transitively by other project modules.
 *
 * We perform this filtering, since if we simply include all external dependencies, regardless of whether
 * they are already loaded transitively, there is a measurable performance impact during module-loading.
