Hi,

I have started learning hive and stuck with this term SerDe. I was going through a blog where it was written this term and nothing was explained. Can anyone explain this term?

Hey,

The SerDe interface allows you to instruct Hive as to how a record be processed. A SerDe is a combination of a Serializer and a Deserializer. The Deserializer interface takes a string or binary representation of a record, and translate it into a Java object that Hive can manipulate. The Serializer, however, will take a Java object that Hive has been working with, and turn it into something that Hive can write to HDFS or another supported system.
