    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.

Type Members

  1. class TimeTypeApiOps extends TypeApiOps

    Client-side (spark-api) operations for TimeType.

    Client-side (spark-api) operations for TimeType.

    This class implements all TypeApiOps methods for the TIME data type:

    • String formatting: uses FractionTimeFormatter for consistent output
    • Row encoding: uses LocalTimeEncoder for java.time.LocalTime

    RELATIONSHIP TO TimeTypeOps: TimeTypeOps (in catalyst package) extends this class to inherit client-side operations while adding server-side operations (physical type, literals, etc.).

    Since

    4.2.0

  2. trait TypeApiOps extends Serializable

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

    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.

    Since

    4.2.0

Value Members

  1. object TypeApiOps extends Serializable

    Factory object for creating TypeApiOps instances.

    Factory object for creating TypeApiOps instances.

    Returns Option to serve as both lookup and existence check - callers use getOrElse to fall through to legacy handling. The feature flag check is inside apply(), so callers don't need to check it separately.
