Class HiveJsonSerDe

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

The native Hive / HCatalog JsonSerDe. Used by Firehose for deserializing data, which means converting it from the JSON format in preparation for serializing it to the Parquet or ORC format. This is one of two deserializers you can choose, depending on which one offers the functionality you need. The other option is the OpenX SerDe.

  • Method Details

    • hasTimestampFormats

      public final boolean hasTimestampFormats()
      For responses, this returns true if the service returned a value for the TimestampFormats 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.

    • timestampFormats

      public final List<String> timestampFormats()

      Indicates how you want Firehose to parse the date and timestamps that may be present in your input data JSON. To specify these format strings, follow the pattern syntax of JodaTime's DateTimeFormat format strings. For more information, see Class DateTimeFormat. You can also use the special value millis to parse timestamps in epoch milliseconds. If you don't specify a format, Firehose uses java.sql.Timestamp::valueOf by default.

      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 hasTimestampFormats() method.

      Returns:

    • toBuilder

      public HiveJsonSerDe.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<HiveJsonSerDe.Builder,HiveJsonSerDe>
      Returns:
      a builder for type T

    • builder

      public static HiveJsonSerDe.Builder builder()

    • serializableBuilderClass

      public static Class<? extends HiveJsonSerDe.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.

    • sdkFieldNameToField

      public final Map<String,SdkField<?>> sdkFieldNameToField()
      Specified by:
      sdkFieldNameToField in interface SdkPojo
      Returns:
      The mapping between the field name and its corresponding field.
