-
What work did the SIG do this year that should be highlighted?
- We helped validating scalability and reliability impact of many features across whole year.
- We extended scalability testing framework and built a number of new optional tests to cover other usecases (e.g. batch workloads)
-
What initiatives are you working on that aren't being tracked in KEPs?
- Localized scalability/performance improvements across the codebase, e.g.:
- Improved LIST calls performance for rare selectors
- Optimizing kube-apiserver compression
- Optimizing watch by reducing number of allocations
- Improved kube-apiserver graceful shutdown
- All the improvements to scalability test frameworks in perf-tests
- Localized scalability/performance improvements across the codebase, e.g.:
-
KEP work in 2022 (v1.24, v1.25, v1.26):
- SIG Scalability doesn't own non-test code, so all below are officially tracked by other SIGs, but are driven (or co-driven) by SIG Scalability.
- Stable
- Beta
- 1040 - Priority and Fairness for API Server Requests - 1.24, 1.25, 1.26
- 1669 - Proxy Terminating Endpoints - 1.26
- Alpha
- Pre-alpha
- 3157 - Watch List - 1.26

What areas and/or subprojects does your group need the most help with? Any areas with 2 or fewer OWNERs? (link to more details)
- Each SIG Scalability subproject could benefit from additional hands. However, the Scalability Test Frameworks and Scalability and Performance tests and validation are the ones with the lower barier to entry - see perf-tests repository. Other areas require both very deep and wide understanding of Kubernetes before making reasonable contributions.
-
What metrics/community health stats does your group care about and/or measure?
- We care mostly about metrics for our main repository perf-tests. We measure them through devstats. We keep track of number of reviewers, opened issues and PRs merged.
-
Does your CONTRIBUTING.md help new contributors engage with your group specifically by pointing to activities or programs that provide useful context or allow easy participation?
- Yes, CONTRIBUTING.md points to maintained list of issues with label
good first issue
.
- Yes, CONTRIBUTING.md points to maintained list of issues with label
-
If your group has special training, requirements for reviewers/approvers, or processes beyond the general contributor guide, does your CONTRIBUTING.md document those to help existing contributors grow throughout the contributor ladder?
- We don't have any special requirements for reviewers/approvers, but most of core areas of sig-scalability require very deep and wide understanding of the whole Kubernetes. It is much easier to start with our testing infrastructure.
-
Does the group have contributors from multiple companies/affiliations?
- Yes, we have contributors from multiple companies.
-
Are there ways end users/companies can contribute that they currently are not? If one of those ways is more full time support, what would they work on and why?
- End users usually come with questions about scalability, they rarely want to contribute.
- End user could also help us by providing and documenting their scalability needs to help us better define our goals.
