designpatterndemo is an open-source project about design pattern examples.
It contains two parts:
part1: most examples in the book 《大话设计模式》, and UML diagrams;
part2: a model task schedule framework, it will be separaeted to be a
independent project in the future. The framework executes R task(R language)
or SQL task with multiply threads. It is a light framework and will be a
stable and high performance framework. It will support DAG tasks like Spark DAG.
Comparing with Spark, while executing DAG tasks, it handles them all in one node
with multiply threads. It is not designed to handle big data.
To get started using designpatterndemo, the full documentation for this release can be
found under the doc/ directory. Now documents are not enough, they are under developed.
