JSON SerDe libraries - Amazon Athena

JSON SerDe libraries

In Athena, you can use SerDe libraries to deserialize JSON data. Deserialization converts the JSON data so that it can be serialized (written out) into a different format like Parquet or ORC.


The Hive and OpenX libraries expect JSON data to be on a single line (not formatted), with records separated by a new line character. The Amazon Ion Hive SerDe does not have that requirement and can be used as an alternative because the Ion data format is a superset of JSON.
