How to access a DynamoDB table from Spark SQL?

0

[https://docs.aws.amazon.com/emr/latest/EMR-Serverless-UserGuide/using-ddb-connector.html#using-ddb-connector-query](This doc page) describes connecting to dynamodb from spark, however it is incomplete.

In particular, I want to know about

val dataFrame = sparkSession.sql("SELECT DISTINCT feature_class \
    FROM ddb_features \
    ORDER BY feature_class;")

Where is ddb_features configured to point to the Features table in DynamoDB? Also, what library do I need to pull in?
