### SIG Scalability

[SIG Scalability][] is responsible for scalability testing, measuring and
improving system performance, and answering questions related to scalability.

For the 1.8 release, SIG Scalability focused on automating large cluster
scalability testing in a continuous integration (CI) environment. The SIG
defined a concrete process for scalability testing, created

or, for function parameters and results, the signature
of a <a href="#Function_declarations">function declaration</a>

storage for a named variable.

Calling the built-in function <a href="#Allocation"><code>new</code></a>
or taking the address of a <a href="#Composite_literals">composite literal</a>
allocates storage for a variable at run time.

- Fixes creationTimestamp: null causing unnecessary writes to etcd ([#116865](https://github.com/kubernetes/kubernetes/pull/116865), [@alexzielenski](https://github.com/alexzielenski)) [SIG API Machinery and Testing]
- Revised the logic for DaemonSet rolling update to exclude nodes if scheduling constraints are not met.
