- v0.2.0 Release

Agenda
- Topology aware routing feature update.
- Removing node taints when Spegel is deployed.
- Remove resolve self check and disable fallback registry by default.
- Share specific problem related to my benchmark pipeline (httpReadSeeker).
Notes
- During benchmarking of image pulls through images (1GB to 30GB) flaky errors related to http read seek errors.
- Explore further simplifying the uninstall process by offering a separate chart to do this on all nodes.
- Sheriffo will create a issue sharing logs to help reproducing the error.
- There may be a need to create a SystemD deployment mechanism for Spegel to enable node local deployment.

Agenda
- Kubecon updates!
- Successful happy-path testing on GKE GCP.
- Thundering Herd load testing.
- Status of requested features.
Notes
- JP is looking at doing a POC with Spegel at Netflix.
- Happy path testing with Spegel shows that it is faster than Dragonfly.
- Thundering heard problem causes issues when multiple clients are hitting the same instance.
- Need some sort of solution to backoff in these kinds of scenarios.
- Some concerns were raised about the long term future of Spegel as it is a project run by a single maintainer. This is a valid point that we don't really have a solution of right now as the amount of contributions from third parties is low.

Agenda
Notes
- Vlad is going to test Spegel on EKS to validate functionaility.
- Dragonfly seems to be to complicated to setup which is pusing a lot of users to Spegel.
- Should consider writing a blog post comparing Spegel to Drangonfly.
- Lazy loading verification is a useful feature to be used together with Spegel. Verifying and documentign compatibility would be helpful.
- Network topology awaremness would be a huge cost saver for larger users. Also would improve performance.
- Airgap cluster when network connection or registry goest down is very useful.

Agenda
Notes
- Sheriffo has been benchmarking Spegel to see how it could be used at Huawei. Initial testing shows pull time or a 30GB image from upstream is around 11 minutes while from Spegel is 6 minutes. This still does not solve the initial pull problem before images can be pulled from Spegel.
- There are many avenues to explore performance improvements that could increase speed when pulling large images.
