EasyScheduler
Easy Scheduler is a distributed workflow task scheduling system, which mainly resolve the problem of "complicated task dependencies but cannot directly monitor the health status of tasks". Easy Scheduler assembles tasks in a DAG manner and can monitor the running status of tasks in real time. Meanwhile, It supports operations such as retry, recovery failure from the specified node, pause and kill tasks.中文描述：Easy Scheduler是一个分布式工作流任务调度系统，主要解决"错综复杂的任务依赖关系，而不能直观监控任务健康状态等问题"。Easy Scheduler以DAG流式的方式将Task组装起来，并可实时监控任务的运行状态，同时支持重试、从指定节点恢复失败、暂停及Kill任务等操作。EasyScheduler由在工作流调度方面工作多年的多位小伙伴研发而成，致力于成为大数据平台的中流砥柱，使调度变得更加容易，更可以从其中文名“易调度”看出我们的初衷，如果你对目前市面上的调度不够满意，非常欢迎使用易调度，欢迎大家加入进来，提出需求，也欢迎贡献代码
flink-recommandSystem-demo
:helicopter::rocket:基于Flink实现的商品实时推荐系统。flink统计商品热度，放入redis缓存，分析日志信息，将画像标签和实时记录放入Hbase。在用户发起推荐请求后，根据用户画像重排序热度榜，并结合协同过滤和标签两个推荐模块为新生成的榜单的每一个产品添加关联产品，最后返回新的用户列表。
flink-sql-lineage
FlinkSQL字段血缘解决方案及源码。FlinkSQL field lineage solution and source code, The core idea is to parse SQL through Calcite to generate a RelNode tree of relational expressions. Then get the optimized logical paln through optimization stage, and finally call Calcite RelMetadataQuery to get the lineage relationship at the field level.
flink-sql-security
FlinkSQL的行级权限解决方案及源码，支持面向用户级别的行级数据访问控制，即特定用户只能访问授权过的行，隐藏未授权的行数据。此方案是实时领域Flink的解决方案，类似离线数仓Hive中Ranger Row-level Filter方案。
