The instability issue detected in release 1.6.0 was tracked back after a lot of community testing. 1.6.1 was released with the stability fix and other critical bug fixes. A 1.6.2 release is considered solely for updated Kubernetes release support. Scale testing is still an issue. The first changes to add scale testing are in progress. Delivery is still planned for 1.7.0. ## Community Health: 9 new Jira accounts were requested. 63 new Jiras created and 56 resolved, with corresponding GitHub PRs: 57 created and 56 resolved. Christmas and Chinese new year have impacted the activity in the community more than in previous years. Expecting activity to pick up again in the next period.
## Description: The mission of Apache YuniKorn is the creation and maintenance of software related to a standalone resource scheduler responsible for scheduling batch jobs and long-running services on large scale distributed systems running in on-premises environments as well as different public clouds ## Project Status: Current project status: Ongoing, with high activity. Issues for the board: We are working through a possible copyright issue in which a 3rd party created a service related to YuniKorn using the YuniKorn name. They have since replaced YuniKorn with unicorn. We think this is not a good enough name separation. ## Membership Data: Apache YuniKorn was founded 2022-03-16 (3 years ago) There are currently 37 committers and 29 PMC members in this project. The Committer-to-PMC ratio is roughly 5:4. Community changes, past quarter: - No new PMC members. Last addition was Chia-Ping Tsai on 2024-03-07. - No new committers. Last addition was Kuan Po Tseng on 2024-03-15. ## Project Activity: Recent releases: 1.6.0 was released on 2024-09-17. 1.5.2 was released on 2024-07-29. 1.5.1 was released on 2023-05-16. Release 1.6.0 has shown some instability in auto scaling clusters. The community is actively investigating the root cause. Scale testing is still an issue. At CoC some of the PMC members spoke with Apache INFRA and we have a path forward that still needs executing. The planning is to make this part of our 1.7.0 release . ## Community Health: 12 new Jira accounts were requested. 175 new Jiras created and 200 resolved, with corresponding GitHub PRs: 183 created and 191 resolved. Multiple community members gave talks at CoC NA. Constructive discussions around the project direction and releases were held during the conference days. We also received and answered questions from other Apache projects on possible integrations.

Issues for the board: No issues to report. ## Membership Data: Apache YuniKorn was founded 2022-03-16 (2 years ago) There are currently 37 committers and 29 PMC members in this project. The Committer-to-PMC ratio is roughly 5:4. Community changes, past quarter: - No new PMC members. Last addition was Chia-Ping Tsai on 2024-03-07. - No new committers. Last addition was Kuan Po Tseng on 2024-03-15. ## Project Activity: Recent releases: 1.5.2 was released on 2024-07-29. 1.5.1 was released on 2023-05-16. 1.5.0 was released on 2024-03-14. After the 1.5.0 release focus shifted to fixing the detected regression in a patch release. The effort was spread over two patch releases. The undetected regression showed the limitations of our current end to end and scale testing setup. The main issue for the community is that we have no ability to run scale tests for each release in a large, hundreds of nodes, Kubernetes cluster. To help with scale testing the community has reached out to AWS to help fill that gap. AWS is willing to sponsor these runs with AWS credits. We are still working through the details on this and hope to use it for the next minor release. Work on the next minor release's features is still progressing. The planned date for this 1.6.0 release has been moved out to next month to compensate for time and effort the two patch releases have taken. ## Community Health: 13 new Jira accounts were requested. 182 new Jiras created and 162 resolved, with corresponding GitHub PRs: 170 created and 175 resolved. A slightly lower number than most quarters due to the patch release focus. The fortnightly community sync is well attended. Most discussions start on slack which often end up in jiras being created. Relevant details are copied from slack to jira. This does require some coaching for new community members. A group of APAC based community members gave a talk at CoC ASIA. CoC NA has multiple talks linked to the project scheduled.

The 1.5.0 release was released as planned, it included 219 jiras. Shortly after release a regression was detected in large busy clusters. The community is finishing up a patch release to mitigate this issue. Work on the next minor release's features is still progressing. The planned date for this 1.6.0 release has not changed. ## Community Health: 21 new Jira accounts were requested. 218 new Jiras created and 250 resolved, with corresponding GitHub PRs: 223 created and 231 resolved. The community came together quickly after noticing a regression in the latest release 1.5.0. Dividing work to speed up the test, analysis and dev cycle as much as possible. Dependency updates are scheduled again as part of the patch release. Target is to fix all known CVEs before a release.

Last addition was Hsuan Zong Wu on 2023-09-06. ## Project Activity: Recent releases: 1.4.0 was released on 2023-11-20. 1.3.0 was released on 2023-06-12. The 1.4.0 release was large with a total of 300 jiras fixed (after cleanup). The community is finishing up release 1.5.0. The release planning has worked around Lunar New Year dates and creating a smaller release than 1.4.0. We have started working on major features for 1.6.0. ## Community Health: 9 new Jira accounts were requested. 276 new Jiras created and 237 resolved, with corresponding GitHub PRs: 218 created and 223 resolved. Translating documentation was taking a lot of time as documents that are getting translated were more complex. The Chinese speaking part of the community has now started a vote to remove the Chinese documentation to reduce maintenance. The YuniKorn web UI is getting some well deserved attention from a group of new contributors. Dependency updates are scheduled before every release, this provides a more structured approach to fixing CVEs. Target is to fix all known CVEs before a release.

The community is in the middle of the 1.4.0 release. Working on the last jiras to be included for a release mid November. YuniKorn as a community gave four presentations at community over code. One presentation for KubeCon NA 2023 in Chicago was accepted. ## Community Health: 31 new Jira accounts were requested. 206 new Jiras created and 203 resolved, with corresponding GitHub PRs: 226 created and 203 resolved. GitHub reviews for the translated documentation are taken more time as the documents that are translated are more complex. We're working on some long term goals around: performance and plugin deployment GA. Part of this goal is a large refactor that has just started to simplify the Kubernetes shim. Delivery spread over at least two releases. This should help not only stability and performance but also invite more contributions. CVEs in dependencies are occurring regularly, a more structured approach to include the updates with fixes needs to be setup by the community.
