Minutes
- DRED measurements for recursive examples
- Tried on some examples
- Model not big enough, no significant slowdown found
- (And no slowdown expected, DRed should theoretically handle this case without a performance loss)
- Regression between 1.2 and 1.5
- Slow editor and code generation performance (may be related to type inferrer)
- Proxy and dangling edge corner case where match set changed
- Will need some detailed testing to improve on both
- Istvan: 1.5.2
- Switch back default for Eval node caching
- Hot-fixes for regressions
- Tutorial CQ started, will probably transition wiki content as well
- DSE Editor demo
- Xtext based DSL for the DSE API
- Generates Java code from the config
- Currently does not really abstract from Java API
- On GitHub under VIATRA org
- Not planned for Eclipse.org contribution
- InGraph demo
- Presented at FOSDEM
- Gabor also went to OCIM
- Incremental query evaluation for OpenCypher
