Target customers: all users. New Functionality/Specification: When users temporarily query Parquet files on OSS, they previously needed to create an external table, specify the columns and field types of the Parquet file, and maintain partitions based on the file directory in OSS. If the Parquet file changed later, they would need to recreate the external table. MC now supports schema-less queries for Parquet format files, allowing direct reading of Parquet files pointing to an OSS location. Known columns can be read in SQL, simplifying the creation and maintenance of external tables and enhancing the user experience.
