在AWS Athena中的json文件中存储多个元素

问题1：在AWS Athena的json文件中存储多个元素

我需要将我的json文件重写为

{“ eventId”：“ 1”，“ eventName”：“ INSERT”，“ eventVersion”：“ 1.0”，“
eventSource”：“ aws：dynamodb”，“ awsRegion”：“ us-west-2”，“ image” ：{“
Message”：“新项！”，“ Id”：101}}，{“ eventId”：“ 2”，“ eventName”：“ MODIFY”，“
eventVersion”：“ 1.0”，“ eventSource”：“ aws：dynamodb“，” awsRegion“：” us-
west-2“，” image“：{” Message“：”此项已更改“，” Id“：101}}，{” eventId“：” 3“， “
eventName”：“ REMOVE”，“ eventVersion”：“ 1.0”，“ eventSource”：“ aws：dynamodb”，“
awsRegion”：“ us-west-2”，“ image”：{“ Message”：“此项目已更改“，” Id“：101}}

那意味着

删除方括号[]将每个元素放在一行中

{.....................}{.....................}{.....................}

问题2。 访问非线性json属性

CREATE EXTERNAL TABLE IF NOT EXISTS <tablename> (  `eventId` string,  `eventName` string,  `eventVersion` string,  `eventSource` string,  `awsRegion` string,  `image` struct <`Id` : string,       `Message` : string>)ROW FORMAT SERDE 'org.openx.data.jsonserde.JsonSerDe'WITH SERDEPROPERTIES (  'serialization.format' = '1',   "dots.in.keys" = "true") LOCATION 's3://exampletablewithstream-us-west-2/';

查询：

select image.Id, image.message from <tablename>;
