7. final class DataFrameWithTime extends DataFrame with Serializable

   

8. class DataFrameWriterJavaFunctions extends AnyRef

   

9. class DummyRDD extends RDD[InternalRow]

   

10. case class ExternalClusterMode(sc: SparkContext, url: String) extends ClusterMode with Product with Serializable

    

    A regular Spark/Yarn/Mesos or any other non-snappy cluster.

11. case class ExternalEmbeddedMode(sc: SparkContext, url: String) extends ClusterMode with Product with Serializable

    

    This is for the "old-way" of starting GemFireXD inside an existing Spark/Yarn cluster where cluster nodes themselves boot up as GemXD cluster.

12. final class Keyword extends AnyRef

    

13. case class LocalMode(sc: SparkContext, url: String) extends ClusterMode with Product with Serializable

    

    The local mode which hosts the data, executor, driver (and optionally even jobserver) all in the same node.

14. final class SampleDataFrame extends DataFrame with Serializable

    

15. trait SampleDataFrameContract extends AnyRef

    

16. abstract class SnappyBaseParser extends Parser

    

    Base parsing facilities for all SnappyData SQL parsers.

17. class SnappyContext extends SQLContext with Serializable with internal.Logging

    

    Main entry point for SnappyData extensions to Spark.

    Main entry point for SnappyData extensions to Spark. A SnappyContext extends Spark's org.apache.spark.sql.SQLContext to work with Row and Column tables. Any DataFrame can be managed as SnappyData tables and any table can be accessed as a DataFrame. This integrates the SQLContext functionality with the Snappy store.

    When running in the embedded mode (i.e. Spark executor collocated with Snappy data store), Applications typically submit Jobs to the Snappy-JobServer (provide link) and do not explicitly create a SnappyContext. A single shared context managed by SnappyData makes it possible to re-use Executors across client connections or applications.

    SnappyContext uses a HiveMetaStore for catalog , which is persistent. This enables table metadata info recreated on driver restart.

    User should use obtain reference to a SnappyContext instance as below val snc: SnappyContext = SnappyContext.getOrCreate(sparkContext)

18. abstract class SnappyDDLParser extends SnappyBaseParser

    

19. case class SnappyEmbeddedMode(sc: SparkContext, url: String) extends ClusterMode with Product with Serializable

    

    The regular snappy cluster where each node is both a Spark executor as well as GemFireXD data store.

    The regular snappy cluster where each node is both a Spark executor as well as GemFireXD data store. There is a "lead node" which is the Spark driver that also hosts a job-server and GemFireXD accessor.

20. class SnappyParser extends SnappyDDLParser

    

21. class SnappySession extends SparkSession with internal.Logging

    

22. class SnappySqlParser extends AbstractSqlParser

    

23. case class SplitClusterMode(sc: SparkContext, url: String) extends ClusterMode with Product with Serializable

    

    This is for the two cluster mode: one is the normal snappy cluster, and this one is a separate local/Spark/Yarn/Mesos cluster fetching data from the snappy cluster on demand that just remains like an external datastore.

24. type Strategy = SparkStrategy

26. class TimeEpoch extends AnyRef

    

    Manages a time epoch and how to index into it.
