Notes
- Announcements
- Upcoming sprint - focusing on fedora 4/5 migration, container support, valkyrie compatibility (if anyone is available to test, otherwise will likely focus on unimplemented search API)
- Fedora User group meeting was successful, slides are online now. There's another one for european timezones in about 2 weeks.
- Breaking Changes
- no new ones
- Mementos
- Binary/Description mementos - reached a conclusion on this last week, to version them together
- Deleting Mementos
- Fedora 5 allows you to delete mementos. That is not possible in Fedora 6 without rewriting the OCFL object.
- Support for delete of mementos is MAY in a specification
- Conclusion is to disallow, Peter will add it to the breaking changes document
- PR Round Up
- Need to wrap up the fcrepo-storage-ocfl so that PR can be opened against fedora core before the sprint
- Will add jiras to document the changes
- We will move fcrepo-storage-ocfl into the fcrepo4 core github organization
- Is it time to rename fcrepo4 organization to fcrepo?
- We will move almost everything in it over to the new name, old path should redirect
- Danny and Andrew will tag team this next week
- Fedora 6 Testing
- Pilot Testing
- NLM has mysql setup, sometimes there are some db connection issues
- Index came up in a reasonable amount of time. Is just 100 migrated records.
- Updated migration util keeps stopping when it hits bad ids, when it is unable to resolve an internal id to a fedora object. Previously it did not halt.
- Calvin will create a Jira ticket to flag this issue, indicate the desired behavior
- Thomas will be able to test migration from 3 to 6 in the next 3-4 weeks
- Emory has gotten support to invest time in testing
- NLM has mysql setup, sometimes there are some db connection issues
- Test tooling
- Andrew has been testing jmeter tests on AWS, using mariadb in docker. First test died in less than 100k objects, something DB related. Will try again with beefier instance.
- Pilot Testing
- High Availability
- How far is fedora 6 from supporting this?
- Transactions are central to the databases, so it would probably work as long as the databases are used across fedoras
- Need object locking
- Need to have shared staging for changes, and shared OCFL storage/repository
- Could fedora be setup with one writer and many readers?
- There is no way to tell fedora 6 that it is in read only
- If you don't use any other ACLs, you could configure a read only root WebACL for some servers to block writes
- Danny will start a document for this topic and the discussion so far
- How far is fedora 6 from supporting this?
Actions
- Danny Bernstein to ensure that a JIRA exists for scenario of transaction does not succeed completely, but rollback does succeed (see: 2020-08-13- Fedora Tech Meeting)
- Peter Winckles to create a JIRA to investigate support for optimistic locking and mutable head (see: 2020-08-13- Fedora Tech Meeting)
- Who: Clarify in documentation that multiple simultaneous writes to OCFL are not supported
- migration-utils - translating RELS-EXT/INT into RDF in Fedora 6: is the functionality there? If not, add it.
