[使用复制命令将GeoJSON文件加载到redshift中

Question

我有一个文件，其中包含我想使用AWS加载到Tableau中的空间数据。我找到了文档，其中指出Amazon Redshift通过GEOMETRY数据类型支持GeoJSON数据。我设法通过以下查询将数据上传到S3存储桶中并在Redshift集群中创建表：

CREATE TABLE public.data (
  PC6 VARCHAR(100),
  Aantal_adr INTEGER,
  geometry GEOMETRY,
  Gemeente2019 INTEGER,
  Wijk2019 INTEGER,
  Buurt2019 INTEGER
);

但是，当我要将GeoJSON文件从S3加载到表中时，表仍然为空，我什至没有收到错误。如何使它工作？

我使用了以下命令：

COPY public.data
FROM 's3://path/folder/data.json'
CREDENTIALS 'aws_access_key_id=x;aws_secret_access_key=y'
json 'auto'
region 'eu-west-1';

这是我的数据示例：

当前不支持将GeoJSON直接加载到GEOMETRY列中。但是，我们将考虑将其添加到路线图中。当发布新功能时，它们会在论坛顶部的常规维护公告中予以注明。

您只能从文本或CSV格式的数据中复制到GEOMETRY列。数据必须采用扩展的众所周知的二进制（EWKB）格式的十六进制形式… https://docs.aws.amazon.com/redshift/latest/dg/copy-usage_notes-spatial-data.html
