presto-gateway 试用以及docker 镜像制作

presto-gateway 是 lyft 团队开源 的prestodb 的工具.以下是一个简单的试用，以及碰到问题的解决
还有就是docker 镜像的制作

Dockerfile

很简单，本地构建然后基于jdk 基础镜像，制作docker 镜像

• 构建方法

  因为默认官方在运行的时候出现了一个索引的bug(主要是因为api 状态处理引起的)，所以使用了我自己的版本

git clone https://github.com/rongfengliang/presto-gateway.git

cd presto-gateway 

mvn clean pacakge

• Dockerfile

FROM azul/zulu-openjdk-alpine:8u222

LABEL AUTHOR="dalongrong"

LABEL EMAIL="1141591465@qq.com"

LABEL VERSION="1.6.1"

WORKDIR /

COPY gateway/target/gateway-1.6.1-jar-with-dependencies.jar /gateway.jar

COPY config.yml.template /config.yml.template

COPY entrtypoint.sh /entrtypoint.sh

RUN chmod +x /entrtypoint.sh

EXPOSE 8888 

ENTRYPOINT [ "/entrtypoint.sh"]

集成gateway 试用

• docker-compose 文件

version: "3"

services:

  proxy:

     image: dalongrong/presto-gateway:1.6.1

     ports:

     - "8888:8888"

     - "8082:8082"

     - "8083:8083"

     build: ./

     volumes:

     - "./config.yml.template:/config.yml.template"

  presto1:

     image: starburstdata/presto

     ports:

     - "8080:8080"

  presto2:

     image: starburstdata/presto

     ports:

     - "8081:8080"

nodejs client 调用

为了使用方便，修改了一现有nodejs 的presto client 支持presto-gateway

• 代码

var presto = require('@dalongrong/presto-client');

var client = new presto.Client({

  user: 'appdemo',

  host: "localhost",

  port: 8888

});

​

client.execute({

  query: 'select * from nation2',

  catalog: 'memory',

  schema: 'default',

  source: 'nodejs-client',

  routingGroup: 'scheduled',

  state: function (error, query_id, stats) {

    console.log(error)

    console.log({

      message: "status changed",

      id: query_id,

      stats: stats

    });

  },

  columns: function (error, data) {

    console.log({

      resultColumns: data

    });

  },

  data: function (error, data, columns, stats) {

    console.log(data);

  },

  success: function (error, stats) {

    console.log(stats)

  },

  error: function (error) {

    console.log(error)

  }

});

访问界面效果

说明

对于使用可以参考官方文档，官方的截图目前有点问题，但是presto-gateway是一个很不错的工具，可以简化我们对于presto 的管理
