\uD83D\uDDE3 Discussion topics

Notes

✅ Action items

• ✅ Check on if more work needs to be done to cover all the predicates from hyrax so that they get persisted to Fedora with a real URI, particularly FITS ones.

Discussed Items:

Nick Homenda is the new Hyrax PO - unable to attend this meeting

• Rebekah Kati will continue to attend because of UNC’s interest.

Fedora 6.5.1 RC still available for testing - has anyone had a chance from this group to look?

• Includes Emory’s feature for OCFL relative paths

• Encoded slashes Fedora ticket in review (https://fedora-repository.atlassian.net/browse/FCREPO-3933?src=confmacro )

  • Not tagged to 6.5.1 - do we need this sooner than later?

  • Dan Field working on it; PR submitted; no harm in creating a RC 2, releasing after the holidays, not a lot of testing done

  • Daniel Pierce will help test 6.5.1 RC.

• Randall Floyd noted bug in 6.5.0: Fedora returns an error if encoded

slash in path;

• Hyrax/Valkyrie has workarounds for it, but would be nice to not to

need it; it would be good to include fix in next RC

• Dan Field will get updated RC in Docker Hub

• Daniel Pierce: Sirenia spec tests all passing, except for custom SQL

queries; working on organizing tests

Performance Testing

• Julie Hardesty: is goal to get this work included in Nurax, then run

performance tests?

• Daniel Pierce: Yes

  • Emily Porter: Emory can also do some anecdotal performance testing;

maybe some comparison testing with pg-nurax

Nurax Challenges: getting enough data in repo for good performance testing

• Brad Watson: may be able to help generate content (100,000 small

files) -- scripted backend

Emory noted issues with concurrency in AWS when doing performance testing

• Emily: parallel processing with multiple processes can slow system

down

• Collin Brittle: set up autoscaling with sidekiq and EC2

• Daniel Pierce: metrics feature of Fedora used at Emory to help investigate?

• Collin Brittle: bottlenecks are lower, in infrastructure

• Emily: haven't stress-tested Fedora yet; Fedora persistence seems to be quick and stable

• Daniel will add Fedora metrics to docker compose

Daniel: use Postgres as Fedora database?

Dan Field: Postgres is most tested, but others also use MariaDB

Arran: Dan will release new RC, will get it into Fedora docker; then into Nurax, and performance testing will continue

Next meeting:

Scheduled for Dec 27th - proposal of a new meeting? Or wait until Jan?

Cancel Dec. 27th meeting; Arran will check in in early January to see where things are at; we'll

communicate asynchronously

• Cancel Dec. 27th meeting
• Arran will check in January to see where testing is at
• Dan Field will release updated RC, with encoded slash PR fix
