ユーザーはSnowflakeにロードする半構造化データを持っていますが、そのデータに対してどのような操作を実行する必要があるのかがわかりません。このような状況において、Snowflakeはどのようなタイプの列の使用を推奨しますか?
正解:D
When dealing with semi-structured data in Snowflake, and the specific types of operations to be performed on the data are not yet determined, Snowflake recommends using the VARIANT data type. The VARIANT type is highly flexible and capable of storing data in multiple formats, including JSON, AVRO, BSON, and more, within a single column. This flexibility allows users to perform various operations on the data, including querying and manipulation of nested data structures without predefined schemas.
