What does SerDe in Hive mean?
In Hive, SerDe stands for Serializer/Deserializer, which is an interface used for reading and writing data in Hive. SerDe is responsible for serializing data into byte streams to store in Hive tables and deserializing byte streams back into raw data when needed. SerDe allows Hive to interact with different data formats such as JSON, CSV, Avro, etc., and perform conversions between different data formats. By customizing SerDe, users can enhance Hive’s functionality to support more data formats. SerDe plays a crucial role in Hive, enabling it to handle a variety of data formats and provide flexibility and scalability.
