Class SparkSQL

java.lang.Object
software.amazon.awssdk.services.glue.model.SparkSQL
All Implemented Interfaces:
Serializable, SdkPojo, ToCopyableBuilder<SparkSQL.Builder,SparkSQL>
@Generated("software.amazon.awssdk:codegen") public final class SparkSQL extends Object implements SdkPojo, Serializable, ToCopyableBuilder<SparkSQL.Builder,SparkSQL>

Specifies a transform where you enter a SQL query using Spark SQL syntax to transform the data. The output is a single DynamicFrame.

  • Method Details

    • name

      public final String name()

      The name of the transform node.

      Returns:
      The name of the transform node.

    • hasInputs

      public final boolean hasInputs()
      For responses, this returns true if the service returned a value for the Inputs property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • inputs

      public final List<String> inputs()

      The data inputs identified by their node names. You can associate a table name with each input node to use in the SQL query. The name you choose must meet the Spark SQL naming restrictions.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasInputs() method.

      Returns:
      The data inputs identified by their node names. You can associate a table name with each input node to use in the SQL query. The name you choose must meet the Spark SQL naming restrictions.

    • sqlQuery

      public final String sqlQuery()

      A SQL query that must use Spark SQL syntax and return a single data set.

      Returns:
      A SQL query that must use Spark SQL syntax and return a single data set.

    • hasSqlAliases

      public final boolean hasSqlAliases()
      For responses, this returns true if the service returned a value for the SqlAliases property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • sqlAliases

      public final List<SqlAlias> sqlAliases()

      A list of aliases. An alias allows you to specify what name to use in the SQL for a given input. For example, you have a datasource named "MyDataSource". If you specify From as MyDataSource, and Alias as SqlName, then in your SQL you can do:

      select * from SqlName

      and that gets data from MyDataSource.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasSqlAliases() method.

      Returns:
      A list of aliases. An alias allows you to specify what name to use in the SQL for a given input. For example, you have a datasource named "MyDataSource". If you specify From as MyDataSource, and Alias as SqlName, then in your SQL you can do:

      select * from SqlName

      and that gets data from MyDataSource.

    • hasOutputSchemas

      public final boolean hasOutputSchemas()
      For responses, this returns true if the service returned a value for the OutputSchemas property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • outputSchemas

      public final List<GlueSchema> outputSchemas()

      Specifies the data schema for the SparkSQL transform.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasOutputSchemas() method.

      Returns:
      Specifies the data schema for the SparkSQL transform.

    • toBuilder

      public SparkSQL.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<SparkSQL.Builder,SparkSQL>
      Returns:
      a builder for type T

    • builder

      public static SparkSQL.Builder builder()

    • serializableBuilderClass

      public static Class<? extends SparkSQL.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
