### SIG Multi-cluster (formerly known as SIG Federation)

[SIG Multi-cluster][] is responsible for infrastructure that supports
the efficient and reliable management of multiple Kubernetes clusters,
and applications that run in and across multiple clusters.

For the 1.8 release, SIG Multicluster focussed on expanding the set of

* A new client `k8s.io/client-go/metadata.Client` has been added for accessing objects generically. This client makes it easier to retrieve only the metadata (the `metadata` sub-section) from resources on the cluster in an efficient manner for use cases that deal with objects generically, like the garbage collector, quota, or the namespace controller. The client asks the server to return a `meta.k8s.io/v1 PartialObjectMetadata` object for list, get, delete, watch, and patch...

of this functionality is to improve efficiency: manually freeing memory
before a garbage collection delays that cycle. Less frequent cycles means
the CPU cost of the garbage collector is incurred less frequently.

This functionality in this package is mostly captured in the Arena type.
Arenas allocate large chunks of memory for Go values, so they're likely to
be inefficient for allocating only small amounts of small Go values. They're

   * efficiency. The base class implementation determines successive Unicode code points and invokes
   * {@link #escape(int)} for each of them. If the semantics of your escaper are such that code
   * points in the supplementary range are either all escaped or all unescaped, this method can be
   * implemented more efficiently using {@link CharSequence#charAt(int)}.

in mind. It is strongly typed and garbage-collected and has explicit
support for concurrent programming.  Programs are constructed from
