Time/PlaceThis meeting is a hybrid teleconference and IRC chat. Anyone is welcome to join...here's the info: AttendeesAgenda- Performance status and next-steps
- 30 seconds on Fedora 3. Maybe 1 minute.
- Versioning design questions and issues
- fcr:versions endpoint
- default behavior
- scope for impending release
- Admin search: expectations and current capabilities
- Ingesting files larger than RAM (works in some Infinispan configs but not others)
Previous Actions
StatusOsmanEsme- Updating benchtool to add support for performing read/update/delete operations, and allowing selecting random number generation impl. at runtime (some people report much faster performance with XORShiftRNG, I see much faster performance with java.util.Random).
- Re-testing large-scale ingest with updated benchtool, to be able to test read/update/delete operations on large-scale repo.
- Testing ingest of large files with different Infinispan backends to diagnose problems.
Mike- Spent some time determining the best way to show that versioning works in fedora 4 and how users should be exposed to it in the pre-beta release.
- Making small fixes to enable demonstration of the feature
- Doing some preliminary design work on the future of this functionality
Eric- began implementing file watcher to provide dynamic filesystem federation
- started looking at messaging module and solr indexing schemes
- code review and documentation
FrankAdamChrisBen Scott- Finished documenting some test profiles – still need to move cluster platform specs to platform profiles
- Read up on Modeshape, Inifinspan
- More documentation tasks (About page), acceptance testing (versioning and search)
- AuthZ/no Authz performance testing (slow progress)
Greg- Working on a content model examples project, with models verified via node types API
- Converted UNC preserved object model to a node type..
- UNC cluster is now ready for benchmarks, test platform documented
- Running minimal config test (single node) and setting up cluster config (4, then 8 nodes)
YeAndrew- Fedora Sponsors meeting today (x2)
- Will be soliciting module configuration management needs/expectations
- All fedora-dev-on-sourceforge emails have been migrated, finishing member migration
- Move "Fedora Futures" wiki-space this weekend?
- Received UI feedback from Robin Dean at Colorado Alliance of Research Libraries
- Fedora website redesign, should be released next week
Minutes- Concern, having consistent approaches
- What are people doing
- Esme: working on benchtool, adds read/update/delete capabilities
- Repeating 500-GB ingest in F3 and F4
- Looking at testing profiles in wiki
- Scott: Has created wiki testing workflows
- Make sure benchtool readme is complete
- Final product: big table with profiles
- Need to surface results and issues as soon as possible
- Ben: ran benchtool with YourKit listening
- Looking into addressing memory-leaks
- Will want to share profiling results, need a download location
Fedora 3- Bug report related to F3
- There is a ticket
- Very surprised the issue was not caught in release/integration testing
Versioning- Cleaning up implementation for the next release
- Version endpoint currently returns RDF that is questionably useful
- Would prefer to return an RDF list of versions
- Need to turn what ModeShape provides into a useful response
- Short-term goals
- Can see a previous version
- Can get a previous version - FedoraContent will not currently work with versions
- Toogle versioning
- Can rollback - later
- Currently versioning is a performance hit
- Need to note if F3 versioning is turned on in testing
- The current F4 versioning is the "worst case scenario", maximum versioning
- Future: need to enable default of versioning off...
Admin Search- Need to clarify current status
- If properties are not defined in node-types, they will not be indexed
- Default indexing dcterms
- Expectations
- identifiers
- enable indexing, but limiting access to certain search results
Ingesting files larger than RAM- "file" config enables ingesting content of size larger than RAM
- Esme, Frank, and Ben working it
Status Review- Greg is working on mapping F3 to F4 content models
- Scott is also interested in this
- Greg to create ticket
