    Enum Constants
    Enum Constant and Description
    `READ_TOO_MANY_TOMBSTONES` The data node read too many tombstones when attempting to execute a read query (see tombstone_failure_threshold).
    `UNKNOWN` The reason for the failure was none of the below reasons or was not recorded by the data node.

    - #### UNKNOWN

          public static final RequestFailureReason UNKNOWN

      The reason for the failure was none of the below reasons or was not recorded by the data node.

    - #### READ_TOO_MANY_TOMBSTONES

          public static final RequestFailureReason READ_TOO_MANY_TOMBSTONES

      The data node read too many tombstones when attempting to execute a read query (see tombstone_failure_threshold).

  - ### Field Detail

    - #### code

          public final int code

      The code to be serialized as an unsigned 16 bit integer

    - #### VALUES

          public static final RequestFailureReason[] VALUES

  - ### Method Detail

    - #### values

          public static RequestFailureReason[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (RequestFailureReason c : RequestFailureReason.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static RequestFailureReason valueOf(java.lang.String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `java.lang.IllegalArgumentException` - if this enum type has no constant with the specified name
        `java.lang.NullPointerException` - if the argument is null

    - #### fromCode

          public static RequestFailureReason fromCode(int code)
