- Performance and scale hackathon
- ModeShape 5 issue
- JMeter tests with MySQL
- Test results
- Request on root resource with a million children fails to respond
- University of Michigan can fund a hack house for performance and scale work
- Can hopefully schedule for this Fall, but the calendar is getting close
- Maybe in Ann Arbor?
- Nick can probably go
- Esme’s calendar is already pretty full
- https://jira.duraspace.org/browse/FCREPO-2060
- Related to PostgreSQL 9.3
- Not seeing an issue with later versions
- No issues with MySQL
- Probably should just recommend using PostgreSQL 9.4+
- Ingest seems to be about 15% faster with Mode5 compared with Mode4
- Esme has done test #4 thoroughly
- Will do test #2 with Mode5
- Has not done test #1 due to lack of disk space
- Currently we only have tests for #1-4
- Andrew will write test #5 and Esme will provide the file
- Esme will run test #3 until running out of disk space
- Need to do some analysis of the test results
- Are these results adequate for the kinds of use cases people actually have?
- Can we push Fedora to its absolute limit in terms of how many resources it can contain?
- Failing to get a count of all child resources
- We can probably work around this by disabling the count
- A better solution would be to store the state, but this is could be tricky
- Or we could stop counting after x children (e.g. there are 1000+ children)
- We do something similar in the HTML UI - we only list the first 100 links
- You can already do this in a REST request by adding a limit
- Andrew will implement a fix
- Is there a real use case for knowing the number of children?
