PySpark is the Python API for Spark.
Public classes:
- L{SparkContext<pyspark.context.SparkContext>}
Main entry point for Spark functionality.
- L{RDD<pyspark.rdd.RDD>}
A Resilient Distributed Dataset (RDD), the basic abstraction in Spark.
- L{Broadcast<pyspark.broadcast.Broadcast>}
A broadcast variable that gets reused across tasks.
- L{Accumulator<pyspark.accumulators.Accumulator>}
An "add-only" shared variable that tasks can only add values to.
- L{SparkConf<pyspark.conf.SparkConf>}
For configuring Spark.
- L{SparkFiles<pyspark.files.SparkFiles>}
Access files shipped with jobs.
- L{StorageLevel<pyspark.storagelevel.StorageLevel>}
Finer-grained cache persistence levels.
Spark SQL:
- L{SQLContext<pyspark.sql.SQLContext>}
Main entry point for SQL functionality.
- L{SchemaRDD<pyspark.sql.SchemaRDD>}
A Resilient Distributed Dataset (RDD) with Schema information for the data contained. In
addition to normal RDD operations, SchemaRDDs also support SQL.
- L{Row<pyspark.sql.Row>}
A Row of data returned by a Spark SQL query.
Hive:
- L{HiveContext<pyspark.context.HiveContext>}
Main entry point for accessing data stored in Apache Hive..
