class DefaultSource extends RelationProvider with SchemaRelationProvider with CreatableRelationProvider with Logging

Cassandra data source extends RelationProvider, SchemaRelationProvider and CreatableRelationProvider. It's used internally by Spark SQL to create Relation for a table which specifies the Cassandra data source e.g.

CREATE TEMPORARY TABLE tmpTable USING org.apache.spark.sql.cassandra OPTIONS ( table "table", keyspace "keyspace", cluster "test_cluster", pushdown "true", spark.cassandra.input.fetch.size_in_rows "10", spark.cassandra.output.consistency.level "ONE", spark.cassandra.connection.timeout_ms "1000" )

    Creates a new relation for a cassandra table.

    Creates a new relation for a cassandra table. The parameters map stores table level data. User can specify vale for following keys

    table -- table name, required keyspace -- keyspace name, required cluster -- cluster name, optional, default name is "default" pushdown -- true/false, optional, default is true Cassandra connection settings -- optional, e.g. spark.cassandra.connection.timeout_ms Cassandra Read Settings -- optional, e.g. spark.cassandra.input.fetch.size_in_rows Cassandra Write settings -- optional, e.g. spark.cassandra.output.consistency.level

    When push_down is true, some filters are pushed down to CQL.
