Minutes

Guava requirement in validation fragment
- Issue created, not high priority
Base index exceptions with Papyrus
- Cannot reproduce, we won’t investigate for now
API tools errors
- Gábor and Zoltán had some issues with this
Rete performance optimization
- Experiments with Eclipse Collections
- Use specialized tuples for common sizes
- Both result in significant memory reduction in CPS benchmark
Base index refactor
- Introduce new variant for instance store using internal IDs
Java 8 BREE in EC vs. VIATRA
- Maybe provide BREE restricted fragments to provide collections
Local search only on query runtime context
- Working version ready
- Some serious performance regressions on initial measurements
  - Possibly related to derived features not available in index
Release schedule suggestion:
- Plan to contribute 1.6.1 for Oxygen.1 (September 27, 2017)
  - Release planned around end July
- Plan to contribute 1.7.0 for Photon M4
Document VIATRA related Eclipse Preferences to docs
- TODO Ábel: initiate place in doc and document experimental TP indexing
Builder performance
- István: seems to be the most important user problem
- Possible directions:
  - Generate less files per pattern
  - Add caches in several places to improve runtime performance
  - Access metamodels through Xtext index
DRed tests and Poset comparator bug
- TODO Tamás: please deal with these topics
