topics:
clustering:
andrew:
ongoing conversation w/ modeshape
HA
- testing on amazon (1-8 nodes) benchtool
- shared S3 bucket
- load balance and configuration robust
- new node joining into shared replication ok
scalability
- heavy writes and reads
- throughput increase w/ added nodes?
- capability of a subset of data to be replicated
- capablity of a subset of data to exist on a # of nodes (redundancy)
-infinispan ongoing development
martin:
- PAAS - redhat openshift, modeshape, HA proxy, further investigation with fedora4
esme/andrew
- multiple machine high level deployment - split-brain concerns with striped related objects
- use cases?
mike:
- fedora3 vs 4 performance, good ingest speed in fedora3
- https://wiki.duraspace.org/display/FF/Performance
andrew:
- fedora4 transactions greatly improve performance
martin:
- amazon s3?
- andrew - node cluster inter-recognition,many infinispan configuration options
- http://infinispan.org/docs/7.0.x/user_guide/user_guide.html
andrew:
- video summaries? mike: through hangouts
- martin - great idea!
next sprint:
- eric,kevin,chris,andrew
federation and authz
- https://wiki.duraspace.org/display/FF/Federation+and+Authorization+ongoing+issues
- Esme/martin: linking to policies rather than within object allowing more centralized configuration
- andrew: working together with UNC next sprint
- Andrew details:
- modeshape pluggable AUTH/N
- external AUTH integration
- Eric - architectural planning decision
- Martin - AUTH concerns of frameworks (hydra/islandora) using fedora4
- level in stack of AUTH responsibility
- Esme: some current support at the hydra level
- possbilities at both islandora and fedora level
