您如何通过 AWS Quicksight 连接到 Redshift Spectrum 上的外部架构/表？
[英]How do you connect to an external schema/table on Redshift Spectrum through AWS Quicksight?
问题描述
I have spun up a Redshift cluster and added my S3 external schema by running
我已经启动了一个 Redshift 集群并通过运行添加了我的 S3 外部架构
CREATE EXTERNAL SCHEMA s3 FROM DATA CATALOG
DATABASE '<aws_glue_db>'
IAM_ROLE '<redshift_s3_glue_iam_role_arn>';
to access the AWS Glue Data Catalog.访问 AWS Glue 数据目录。 Everything is fine on Redshift, I can query data and all is well. Redshift 上一切正常，我可以查询数据并且一切正常。 On Quicksight, however, the table is recognized but is empty.然而，在 Quicksight 上，该表被识别但为空。
Do i have to move the data into Redshift?我是否必须将数据移动到Redshift 中？ If so, would the only reason I should be using Redshift be to process Parquet files?如果是这样，我应该使用 Redshift 的唯一原因是处理 Parquet 文件吗？

You should be able to select external tables from redshift, I think the role you're using is missing access to s3您应该能够从 redshift 中选择外部表，我认为您使用的角色缺少对 s3 的访问权限
