AWS Kinesis Firehose到Redshift的记录应如何格式化? [英] How should records be formatted for AWS Kinesis Firehose to Redshift?

问题描述

请考虑以下内容:

• Redshift中一个名为"people"的表，其中包含字段ID，名称和年龄
• 称为"people"的运动型流水流，配置为写入"people"表，并且"Redshift表列"的值为"id，name，age"

目前尚不清楚如何格式化数据" blob.这是一个代码示例，其中数据用制表符分隔:

It's not clear how to format the 'Data' blob. Here's an example of what the code looks like with the data separated by tabs:

let AWS = require('aws-sdk');
let firehose = new AWS.Firehose();
let params = {
  DeliveryStreamName: 'people',
  // id,name,age
  Records: [{Data: '4ccf6d3a-acdf-11e5-ad54-28cfe91fa8f1\tBob\tSmith'}]
};
firehose.putRecordBatch(params, (err, result) => {
  console.log(err || result);
});

以下是我检查过的一些文档:

Here are some of the docs I have checked:

• http://docs.aws.amazon.com/firehose/Latest/APIReference/API_PutRecordBatch.html
• http://docs.aws.amazon. com/firehose/latest/dev/writing-with-sdk.html
• http://docs.aws.amazon. com/AWSJavaScriptSDK/latest/AWS/Firehose.html#putRecordBatch-property

• http://docs.aws.amazon.com/firehose/latest/APIReference/API_PutRecordBatch.html
• http://docs.aws.amazon.com/firehose/latest/dev/writing-with-sdk.html
• http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/Firehose.html#putRecordBatch-property

推荐答案

答案在这里:

http://docs.aws. amazon.com/redshift/latest/dg/copy-parameters-data-format.html

字段必须为管道'|'默认情况下分隔.行应该用换行符分隔.

Fields need to be pipe '|' separated by default. Rows should be separated by new lines.

更新后的更正代码:

let AWS = require('aws-sdk');
let firehose = new AWS.Firehose();
let params = {
  DeliveryStreamName: 'people',
  // id,name,age
  Records: [{Data: '4ccf6d3a-acdf-11e5-ad54-28cfe91fa8f1|Bob|Smith\n'}]
};
firehose.putRecordBatch(params, (err, result) => {
  console.log(err || result);
});
