AWS Athena 分区键变为“varchar”
[英]AWS Athena Partition Keys becomes as 'varchar'
问题描述
For example, I have a two partition keys that are account_id as int and record_date as date.
例如，我有两个分区键，分别是作为 int 的 account_id 和作为日期的 record_date。 When I executed a query, Athena says these are varchar.当我执行查询时，Athena 说这些是 varchar。 I have to query with 'key'.我必须用“钥匙”查询。 Is it a usual case or I did something wrongly?这是常见情况还是我做错了什么？

If you use a data crawler for partition repair and crawler configuration not set as don't change schema, crawler changes partition keys type as string.如果您使用数据爬虫进行分区修复并且爬虫配置未设置为不更改架构，则爬虫会将分区键类型更改为字符串。
