用于复制到Redshift的Java SDK [英] Java sdk for copying to Redshift

问题描述

是否可以通过java jdbc连接从S3向Redshift触发复制命令?

Is it possible to fire a copy command from S3 To Redshift through java jdbc connection?

示例: 从's3://'凭据复制测试'aws_access_key_id = xxxxxxx; aws_secret_access_key = xxxxxxxxx'

Example: copy test from 's3://' CREDENTIALS 'aws_access_key_id=xxxxxxx;aws_secret_access_key=xxxxxxxxx'

推荐答案

可以尝试以下代码

String dbURL = "jdbc:postgresql://x.y.us-east-1.redshift.amazonaws.com:5439/dev";
String MasterUsername = "userame";
String MasterUserPassword = "password";

           Connection conn = null;
            Statement stmt = null;
            try{
               //Dynamically load postgresql driver at runtime.
               Class.forName("org.postgresql.Driver");


               System.out.println("Connecting to database...");
               Properties props = new Properties();


               props.setProperty("user", MasterUsername);
               props.setProperty("password", MasterUserPassword);
               conn = DriverManager.getConnection(dbURL, props);
               stmt = conn.createStatement();
               String sql="copy test from 's3://' CREDENTIALS     'aws_access_key_id=xxxxxxx;aws_secret_access_key=xxxxxxxxx'"
                int j = stmt.executeUpdate(sql);

                stmt.close();
               conn.close();
            }catch(Exception ex){
               //For convenience, handle all errors here.
               ex.printStackTrace();
            }
