Enum UnderStorageType

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<UnderStorageType>
    @ThreadSafe
public enum UnderStorageType
extends java.lang.Enum<UnderStorageType>
    Specifies the type of data interaction with Alluxio's Under Storage. This is not applicable for reads. Only writing temporary data is suggested to use type NO_PERSIST where writing to Under Storage will be skipped and data may be lost when evicted from Alluxio storage.

      • values

        public static UnderStorageType[] 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 (UnderStorageType c : UnderStorageType.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static UnderStorageType 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

      • isSyncPersist

        public boolean isSyncPersist()
        Returns:
        whether the data should be persisted to the under storage synchronously

      • isAsyncPersist

        public boolean isAsyncPersist()
        Returns:
        whether the data should be persisted to the under storage asynchronously
