Rocketmq Streams SQL

Rocketmq Streams SQL 为 Rocketmq Streams 的开发提供了基于SQL的开发体验， 让基于消息队列的流式开发更加容易；

Features

• 采用标准的流式SQL规范，可以与其他的流计算框架如Flink完美兼容；
• 兼容Flink自带的udf、udaf和udtf，除此之外，用户还可以通过实现相关接口来轻松扩展函数；

TableStream Example

    import com.alibaba.rsqldb.clients.*;
    String sql="CREATE FUNCTION now as 'com.sql.Function';\n"
                           + "CREATE TABLE graph_vertex_proc (\n"
                           + "  `time` varchar,\n"
