    Core Spark functionality.

    Core Spark functionality. org.apache.spark.SparkContext serves as the main entry point to Spark, while org.apache.spark.rdd.RDD is the data type representing a distributed collection, and provides most parallel operations.

    In addition, org.apache.spark.rdd.PairRDDFunctions contains operations available only on RDDs of key-value pairs, such as groupByKey and join; org.apache.spark.rdd.DoubleRDDFunctions contains operations available only on RDDs of Doubles; and org.apache.spark.rdd.SequenceFileRDDFunctions contains operations available on RDDs that can be saved as SequenceFiles. These operations are automatically available on any RDD of the right type (e.g. RDD[(Int, Int)] through implicit conversions.

    Java programmers should reference the org.apache.spark.api.java package for Spark programming APIs in Java.

    Classes and methods marked with Experimental are user-facing features which have not been officially adopted by the Spark project. These are subject to change or removal in minor releases.

    Classes and methods marked with Developer API are intended for advanced users want to extend Spark through lower level interfaces. These are subject to changes or removal in minor releases.

trait TypeApiOps extends Serializable

Client-side (spark-api) type operations for the Types Framework.

This trait consolidates all client-side operations that a data type must implement to be usable in the Spark SQL API layer. All methods are mandatory because a type cannot function correctly without string formatting (needed for CAST to STRING, EXPLAIN, SHOW) or encoding (needed for Dataset[T] operations).

This single-interface design was chosen over separate FormatTypeOps/EncodeTypeOps traits to make it clear what a new type must implement - there is one mandatory interface, and it contains everything required. Optional capabilities (e.g., proto, Arrow, JDBC) are defined as separate traits that can be mixed in incrementally.

RELATIONSHIP TO TypeOps:

  • TypeOps (catalyst): Server-side operations - physical types, literals, conversions
  • TypeApiOps (spark-api): Client-side operations - formatting, encoding

The split exists because sql/api cannot depend on sql/catalyst. For TimeType, TimeTypeOps (catalyst) extends TimeTypeApiOps (sql-api) to inherit both sets of operations.
