• CC: Maccabee Levine
  • Continued discussion about AWS cost increases, especially due to Eureka.  ACRG will present at next CC meeting on 9/9.
  • Agenda(s) for CC and cross-council meetings at WOLFcon.
• PC: Tod Olson
  • Discussion of module review process, moved out of pilot into accepted
• RMS Group (today):
  • CSP release cadence: Release on demand (not fixed 2 week or 4 week cadence)
  • Stay on Spring Boot 3.3 for Ramsons
    • Upgrade to 3.4 in Sunflower. This means we'd be unsupported for some period of time. If we're lucky and there aren't any Critical/High security vulnerabilities in these frameworks, all is good. However, if there are, we would be in the position where now we need to get teams to drop what their doing and upgrade unexpectedly, backporting the changes to Ramsons. 
    • Upgrade Ramsons to 3.4 if there's a security vulnerability between 2025-05-23 (End of Support of Spring Boot 3.3) and Trillium release Q4 2025 (= End of Support of Ramsons); this results in a huge CSP and requires extensive testing

  • TC - review possibility to get enterprise support from Spring Framework

    • 500 $ per Pod or Core: https://itprice.com/vmware-price-list/academic%20spring%20runtime.html

    • FOLIO devOps to change CI pipelines, Docker hub repositories, etc. to support closed source

  • Reserve time in Trillium to upgrade to version 3.5

    • This requires (milestone or) release candidate versions of Spring Boot for FOLIO bug fest if Trillium bug fest starts November 2025 or earlier.
• Security Team: 
  • ongoing triage of potential vulnerabilities
  • Jiras gets unembargoed when closed (when fixed or security group approves as not affected).
• Tri-council Application Formalization:  
  • Discussion of impact of dual okapi/eureka envs on cost and what exit from okapi in community envs would require
  • Discussion of application spreadsheets created by Charlotte and Kirstin
  • Discussion of WolfCon session

• 28 Aug 2024 - Dedicated Discussion: Refine the OST process to ensure better coordination between SysOps and the TC
• 02 Sep 2024 - US holiday (regular TC meeting moved to Wed)
• 04 Sep 2024 - Regular TC Meeting
• 09 Sep 2024 - Regular TC Meeting
• 11 Sep 2024 - Dedicated discussion: Continuation of architectural decision-making discussion

• mod-marc-migrations working on game plan
• tcr-42 waiting on PC approval
• tcr-45 moved to Ingolf Kuss via rotation
  

All

All

Need to log decisions for the following:  (see above)

• Discussions on the necessity of a Wednesday meeting to address the OST process and involvement of Sysops.

Check Recurring Calendar

• Spring Boot 3.4 (and Spring Framework 6.2)
  • Today RMS group has made the decision, see Liaison Updates section above.
• Sunflower
  
  • The Spring Boot support period of 12 months for a single minor release has the same length as FOLIO's support period of ~ 12 months, however, these periods usually don't align.
  • Regarding Backend "First Party Libraries / Frameworks": A library/framework needs to support only one of the versions allowed in the "Third Party Libraries / Frameworks" list. This should be clarified in the description.
  • Adding folio-s3-client to first party libraries and the AWS and MinIO clients to third party libraries. folio-s3-client is an abstraction for the AWS and MinIO client.
  • Java 21
    • No objections from developers, the migration from 17 to 21 will be easy, simply bump the folio-java-docker image in the Dockerfile and the jenkins-slave-docker image in the Jenkinsfile.
    • Need to contact DevOps whether they can provide a Java 21 version of folio-java-docker and jenkins-slave-docker before the Sunflower development starts; recent commits (folio-java-docker history, jenkins-slave-docker history) have been made by David Crossley, John Malconian, and Julian Ladisch.

There has been a long discussion 3-4 years ago about how FOLIO should handle reference data upon upgrades. See these links for background:

• Original problem statement
• Input from SysOps SIG
• Proposals considered by Tech Council working group
• Recommendation from Tech Council working group

Previous Notes:

Background and Problem Statement

• The issue at hand involves the handling of reference data during system upgrades. In previous upgrades, some institutions experienced data loss where customized reference data was overwritten by default settings during the upgrade process.
• This problem was particularly highlighted in recent upgrade cycles, prompting a need for a more robust solution to preserve institution-specific customizations.

Existing Solutions and Approaches

• Circulation Module Example:

  • The circulation module had addressed this issue by implementing a solution where reference data is only installed during the initial setup and skipped in subsequent upgrades unless new data is introduced in the upgrade. This approach prevents the overwriting of existing customized data.
  • The TC discussed whether this solution could be standardized and applied across other modules facing similar issues.

• Challenges with Current Approach:

  • While the circulation module's solution is effective for preserving existing data, it does not account for scenarios where the reference data schema changes in new versions (e.g., adding new fields or making structural changes). In such cases, simply skipping the installation might not be sufficient, and more complex handling might be required.

Discussion Points

• Standardization Across Modules:
  • The TC debated whether a similar approach should be mandated across all modules to ensure consistency and prevent data loss during upgrades. However, it was noted that this might require module-specific adjustments, depending on how each module manages its reference data.
• Need for a Broader Solution:
  • There was recognition that a broader, more flexible solution might be necessary to handle various scenarios, such as changes in reference data structures. This could involve more sophisticated checks during the upgrade process to determine whether and how data should be updated or preserved.

Potential Actions

• Subgroup Formation:
  • The idea of forming a new subgroup to focus on developing a comprehensive strategy for reference data handling during upgrades was floated. This subgroup could explore creating an RFC (Request for Comments) to propose a standardized approach across the project.
• Review of Previous Work:
  • It was suggested that before moving forward, the TC should review previous efforts and discussions on this topic, including past proposals and proof-of-concept work that may have stalled due to resource constraints. This review would help ensure that any new efforts build on previous work rather than starting from scratch.

Next Steps

• Further Discussion:
  • The TC agreed to revisit this discussion in the next meeting, with members encouraged to review past work and consider whether they are interested in participating in a potential subgroup. The goal would be to establish a clear path forward for managing reference data during upgrades across all modules.

Today:

• A subgroup should be formed to make progress on this.

Review decisions that are in progress.  Can any of them be accepted?  rejected?

Currently there is a PoC, developed by Maccabee Levine, of a utility to catalog Github PRs that have been labeled with the "breaking change" label. We would like to get developer feedback on the feasibility of this label being used more often, and the usefulness of this utility. 

Previous Notes:

• A workflow for these pages. When do they transition from one state to another. Do we even need statuses at all ?

Stripes architecture group has some questions about the Poppy release.

Zak: A handshake between developers, dev ops and the TC. Who makes that decision and how do we pass along that knowledge ? E.g. changes in Nodes and in the UI boxes. How to communicate this ? We have a large number of teams, all have to be aware of it.  TC should be alerted that changes are happening. We have a couple of dedicated channels for that. Most dev ops have subscribed to these channels. How can dev ops folk raise issues to the next level of community awareness ? There hasn't been a specific piece of TC to move that along.

Craig: There is a fourth group, "Capacity Planning" or "Release Planning". Slack is the de facto communication channel.  There are no objections to using Slack. An example is the Java 17 RFC. 

Craig: The TC gets it on the agenda and we will discuss it. The TC gets the final say.

Marc Johnson: We shouldn’t use the DevOps Channel. The dev ops folks have made it clear that it should only be used for support requests made to them.

Jakub: Our responsibility is to avoid piling up technical debt.

Marc: Some set of people have to actually make the call. Who lowers the chequered flag ?

Craig: It needs to ultimately come to the TC at least for awareness. There is a missing piece. Capacity Planning needs to provide input here. 

Marc: Stakeholders / Capacity Planning could make that decision. Who makes the decision ? Is it the government or is it some parts of the body ?

Marc: the developers community, the dev ops community and sys ops are involved. For example the Spring Framework discussion or the Java 17 discussion. But it was completely separate to the TC decision. It is a coordination and communication effort.

Marc: Maybe the TC needs to let go that they are the decision makers so that they be a moderating group.

Jakub: I agree with Marc. But we are not a system operating group. Dependency management should be in the responsibility of Release management. There are structures in the project for that.

Jason Root: I agree with Jakub and with Marc also. Policies should drive operational/release/support aspects of Folio.

Jason Root: If the idea of “support” is that frameworks are supported, then of course the project should meet that.

Marc Johnson
Some group needs to inform OleksAii when a relevant policy event occurs.
These documents effectively ARE the manifestation of the policy.

Craig: This is a topic for the next Monday session.

Craig to see if Oleksii Petrenko could join us to discuss the process for updating the officially supported technologies lists.

Possible topic/activity for a Wednesday session:

Discuss/brainstorm:

• Ideas for the type of developer-facing documentation we think would be most helpful for new developers
• How we might bring existing documentation up to date and ensure it's consistent 
• etc.
