Specification of various Window and Trigger APIs in Samza
- Defined APIs for specifying different types of windows - sessions,
tumbling, global and keyed variants.
- Defined APIs for specifying early and late triggers for a window.
- Standardized all above Window types to be expressed as a combination of
default, early and late triggers.
- Defined classes for different types of trigger specifications.
- Hide the WindowState class from programmers and move it from samza-api to
samza-operator. We can choose to add it later if need be.
- Removed some implementation classes in Window and Trigger. We can revisit
them later when we implement Windows.
- New API for specifying Time durations meaningfully in Samza.
- Unit tests for most of the above changes.
- Misc. Documentation, readability related changes to public APIs.
