Notes
- Jira move was done yesterday, but we need to setup some proxy server to redirect to the new server. Permissions on the old site should be made read-only. If you had an account before, you can use the reset password link to get access to the account.
- Plan is to have some camel-toolbox release at the time of the Fedora 6.0.0 production release.
- Modeshape PR needs to be reviewed and then merged and then a release of Fedora 5.1. Open PR to be reviewed/tested/merged.
- Fedora 6 Release
- Aim for a release for the week of the 24th assuming no issues are discovered.
- Above RC would put a release date at the week of June 14th.
- Danny to test core dump and post results of memory analysis.
- Some migration-utils metrics to test performance of migrations.
- Performance related issues.
- FCREPO-3695 and FCREPO-3696 should be resolved by https://github.com/fcrepo/fcrepo/pull/1896
- FCREPO-3697 is not started but should wait for above PR to be merged.
- Also https://github.com/fcrepo/fcrepo/pull/1895 for adding search transactions and making the updating of the search index synchronous with the other operations.
- Some updates
- Add some caching for ocfl mapping queries and containment queries.
- Newly discovered memory leak
- Question of OCFL performance issues when writing to NAS and isolon. Option to not calculate a checksum at the OCFL level and just use the one calculated in Fedora.
- Some of the other tickets are already in review
Actions
- Look through migration util commits since December to see if there are any potential causes of performance drop off.
