# StreamQL

![JAVA 8](https://img.shields.io/badge/JDK-1.8+-brightgreen.svg)

Stream + Druid Sql Parser = StreamQL

## 使用

```java

public static void main(String[] args) {

    StreamQL.sql("select * from '/test/1'")

            .build()

            .execute((table) ->

                    getMessage().stream()

                    .filter(data -> data.getTopic().equals(table)))

            .forEach(System.out::println);

}

private static List getMessage() {

    List data = new ArrayList<>();

    for (int i = 0; i < 10; i++) {

        Message message = new Message();

        message.setId(i);

        message.setTopic("/test/" + i);

        message.setClientId("clientId" + i);

        message.setTimestamp(System.currentTimeMillis());

        data.add(message);

    }

    return data;

}

```
