Amazon Glue Scala DynamicRecord class

Package: com.amazonaws.services.glue

class DynamicRecord extends Serializable with Writable with Cloneable

A DynamicRecord is a self-describing data structure that represents a row of data in the dataset that is being processed. It is self-describing in the sense that you can get the schema of the row that is represented by the DynamicRecord by inspecting the record itself. A DynamicRecord is similar to a Row in Apache Spark.

Def addField

def addField( path : String,
              dynamicNode : DynamicNode
            ) : Unit 

Adds a DynamicNode to the specified path.

Def dropField

 def dropField(path: String, underRename: Boolean = false): Option[DynamicNode]

Drops a DynamicNode from the specified path and returns the dropped node if there is not an array in the specified path.

Returns a scala.Option Option (DynamicNode).

Def setError

def setError( error : Error )

Sets this record as an error record, as specified by the error parameter.

Returns a DynamicRecord.

Def isError

def isError

Checks whether this record is an error record.

Def getError

def getError

Gets the Error if the record is an error record. Returns scala.Some Some (Error) if this record is an error record, or otherwise scala.None .

Def clearError

def clearError

Set the Error to scala.None.None .

Def write

override def write( out : DataOutput ) : Unit 

Def readFields

override def readFields( in : DataInput ) : Unit 

Def clone

override def clone : DynamicRecord 

Clones this record to a new DynamicRecord and returns it.

Def schema

def schema

Gets the Schema by inspecting the record.

Def getRoot

def getRoot : ObjectNode 

Gets the root ObjectNode for the record.

Def toJson

def toJson : String 

Gets the JSON string for the record.

Def getFieldNode

def getFieldNode( path : String ) : Option[DynamicNode] 

Gets the field's value at the specified path as an option of DynamicNode.

Returns scala.Some Some (DynamicNode) if the field exists, or otherwise scala.None.None .

Def getField

def getField( path : String ) : Option[Any] 

Gets the field's value at the specified path as an option of DynamicNode.

Returns scala.Some Some (value).

Def hashCode

override def hashCode : Int 

Def equals

override def equals( other : Any )

DynamicRecord object

object DynamicRecord

Def apply

def apply( row : Row,
           schema : SparkStructType )

Apply method to convert an Apache Spark SQL Row to a DynamicRecord.

Returns a DynamicRecord.
