Serde Property The statement to increase the Serde property is as follows: ALTER TABLE TABLE_NAME SET SERDE serde_class_name [with Serdeproperties serde_properties] ALTER TABLE table_name SET S Erdeproperties (property_name = Property_value,property_name = Property_value, ...) This statement allows the addition of custom metadata to the Serde object. The Serde property is passed to the table Serde when Serde is initialized by hive. Modifying the s

A partitioned column is also not an actual field in a table, but one or more pseudo-columns. This means that the information and data of the partition column are not actually saved in the data file of the table.
