However, you can create a … 2019-03-23 Implicitly Declare a Schema¶. To create a Dataset from MongoDB data, load the data via MongoSpark and call the JavaMongoRDD.toDF() method. Despite toDF() sounding like a DataFrame method, it is part of the Dataset API and returns a Dataset. The dataset's schema is inferred whenever data is read from MongoDB and stored in a Dataset without specifying a schema-defining Java bean. When using filters with DataFrames or the Python API, the underlying Mongo Connector code constructs an aggregation pipeline to filter the data in MongoDB before sending it to Spark. Use filter() to read a subset of data from your MongoDB collection.

However, we recommend using the Snowflake Connector for Spark because the connector, in conjunction with the Snowflake JDBC driver, has been optimized for transferring large amounts of data between the two systems. spark-submit command including mysql connector 0 Cannot build a scala program “sbt package” failed with Exception in thread “main” java.sql.SQLException: No suitable driver Apache Spark.
