Also, since M5 the DSL layer, the representation layer and the implementation layer are highly decoupled, so we can much more easily hack around with the internals than before. I think two main architectural areas are to be covered: - Dynamic streams usage: the current DSL is very rigid as in the layout of the streams are mostly static after being materialized. We need to solve this in a way that is not a collection of ad-hoc hacks and has similar safety properties than the most common stream stages. - Graph interpreter support: this will allow us to expose much richer APIs than the current FlexiMerge/FlexiRoute and unify it with the PushPullStage infrastructure. It will allso allow users to demarcate regions of a graph they want to map to an actor. I.e. you will be able to execute a complex graph/flow inside one actor instead one actor for each stage. I believe this will also improve performance. Performance optimizations should not interfere with the above goals, therefore we are not jumping right into them, but we are very eager! -Endre > thanks > G > > On Wednesday, 27 May 2015 13:49:10 UTC+2, drewhk wrote: >> >> Hi, >> >> At the current point the aim of streams 1.0 was to reach a desired >> functionality level.
