Reminder(s)

  • Go RFC still open - admin action required, only a PoC - nothing formal required other than closing the pull request.
  • Still Need Decision Log record for application formalization, Go, configuration RFCs. Todd mentions having the record all one place is useful
1 minDecision LogAll

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

  • Decentralized configuration - Florian is working on this, will come back around next week.
    • Write-up in draft, can be accepted. Florian says it's pretty settled
  • Go programming language

Officially Supported Technologies (OST)

All

Check Recurring Calendar

    • Message to channels about RFCs.  Due end of next week.  Craig McNally and Jenn Colt will confer about posting to the listed channels.  Maybe find automation.
    • Need to Review comments on Sunflower page and move to accepted if no further changes are required.
      Julian wants to go to JDK 21, LTS version, Marc concerned about the Operations work this will incur, Taras agrees this will take some heavy lifting

  • Julian Ladisch: "See https://folio-project.slack.com/archives/C01HUKJCMC7/p1722859432396769 why I suggest to consider bumping the Officially Supported Technology version for Spring Boot (and Spring Framework) for Ramsons." (Spring Boot 3.3 to 3.4) This is a regularly scheduled release, giving developers a head's up would be a good thing.
  • Not clear on Sunflower version scope timeline and supported vert.x version

    Several more action items on Officially Supported Tech page. SysOps needs to be included in the informational process.

Time PermittingReference Data Upgrade

Hold until after Aug 2.

In the Sys Ops SIG meeting the topic of Reference Data Upgrades came up. The SIG thinks that the solution of this problem for mod-inventory-storage is not enough, but that this problem needs to be solved in a general way, for all modules.

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


Previous Notes:

Marc Johnson points out he remembers a difference set of formal processes for this from the previous subgroup

Jason R. asks if the issue is that you cannot specify per-module what type of data to load, or that no matter what is specified the upgrade process overrides it

Marc mentions that the proposal to correct this by Vince is a very involved and complex workflow. There has been no developer resources allocated to correct this issue and address the proposal

No easy solution to this problem because the original default data is lost to time and change

Will reach out to Julian Ladisch when he returns

Notes:

Ingolf Kuss is on vacation.  Lets wait until Julian and Ingolf are both here.


Today:

  • Maccabee Levine Is this the same as the PC subgroup working to improve sample data?
    • Marc Johnson Not sure.
    • Tod Olson Thought we were taking about the same thing as the group a lot of people were on for a while.
    • Craig McNally Reference data working group a couple years ago is what sysops is taking about.  Not sure if it's the same as the sample data group.
    • Tod Olson Was much more involved the last time.
    • Maccabee Levine Just make sure the two groups are aware of each other.
  • When Ingolf Kuss returns, can get more info.
  • Tod Olson This new PC group is about sample data.  Years ago data was contributed.  Now new functionality, there are no sample data test cases.
  • Maccabee Levine Example, in snapshot there are no orders connected to any invoices.
  • Tod Olson Reference data can be customized (i.e. material types) or added to, but often is not.  Some stable conventions are needed for the reference environments.  It's a fuzzy boundary.

Reacted to " actually it also re..." with 👍
10:48:52 From Julian Ladisch to Everyone:
Vert.x 4 will remain supported for 2 years.

10:54:01 From Julian Ladisch to Everyone:
The futurization of Vert.x has been communicated in RMB 32.0:

https://github.com/folio-org/raml-module-builder/blob/master/doc/futurisation.md
Vert.x has deprecated the callback methods so that deprecation warnings pop up in IDEs and linters like sonar.
10:55:13 From Taras to Everyone:
AWS S3: AWS SDK for Java v2 must be used
MinIO: need to review with the DevOps community which versions are in use currently. https://github.com/minio/minio/releases/tag/RELEASE.2024-07-16T23-46-41Z is the last stable release.
Kafka (MSK): 3.5.1 or higher (https://docs.aws.amazon.com/msk/latest/developerguide/supported-kafka-versions.html

Topic Backlog

Decision Log ReviewAll

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

Translation SubgroupAllSince we're having trouble finding volunteers for a subgroup, maybe we can make progress during a dedicated discussion session?
Communicating Breaking ChangesAll

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. 

Officially Supported Technologies - UpkeepAll

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.


Dev Documentation VisibilityAll

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.
API linting within our backend modulesAll

https://folio-project.slack.com/archives/CAQ7L02PP/p1713343461518409


Hello team, I would like to discuss API linting within our backend modules. Some time ago, we transitioned our linting process from Jenkins to GitHub Actions as outlined in https://folio-org.atlassian.net/browse/FOLIO-3678. I am assuming that this move was done via some technical council decision. Please correct me if I'm wrong.
In my observations, I've found two problems:
  1. Schema linting does not occur if the schemas are in YAML format.
  2. There are issues with resolving some deeper references during API linting.
Although I'm unsure about how to improve the existing linting implementations within Folio, I propose to consider an open-source solution that handles OpenAPI linting effectively and allows us to define custom rules. For your reference: https://stoplight.io/open-source/spectral A test of this solution can be found in this PR: https://github.com/folio-org/mod-search/pull/567. The same PR also provides an example of custom rule definition: https://github.com/folio-org/mod-search/pull/567/files#diff-d5da7cb43c444434994b76f3b04aa6e702c09e938de09dbc09d72569d611d9ab.Also, by employing 'Spectral', I discovered AsyncAPI (https://www.asyncapi.com/en), an API design tool similar to OpenAPI but for asynchronous interactions. I suggest that we consider using AsyncAPI in FOLIO to generate documentation for Kafka interactions.


PR TemplatesAll

https://folio-project.slack.com/archives/CAQ7L02PP/p1713445649504769

Hello team, Small request to consider.
Regarding pr templates.
  1. From my perspective, pr template is not good idea. Even the biggest open source projects that are contributed by many people don't have any pr template. Currently what we have for acq modules https://github.com/folio-org/mod-orders-storage/blob/master/PULL_REQUEST_TEMPLATE.md
  2. These pr template is inconsistent in different teams.
What I suggest is that, pr template shouldn't be any instructions, because most developer who are creating pr have already understand the rules. If we put just two section into template, it will encourage developers to write more about their work and that lead to knowledge  sharing among developers.
Java 21All

Proposed Mod KafkaAll

https://folio-project.slack.com/archives/CAQ7L02PP/p1714471592534689

Mike Taylor

Proposal. If and only if a FOLIO instance is running Kafka, it should insert and enable a module called mod-kafka, which consists entirely of a module descriptor that says it provides the interface kafka. The purpose is so that other modules can use the standard <IfInterface> and similar tools to determine whether they should attempt Kafka operations. Rationale: the FOLIO ILS depends absolutely on Kafka, but other uses of the platform will not. One such example: a dev platform that includes only mod-users, used as a source of change events for Metadb.
