      • Backward

        public static final SchemaAutoUpdateCompatibilityStrategy Backward
        Messages written in the previous schema can be read by the new schema. To be backward compatible, the new schema must not add any new fields that don't have default values. However, it may remove fields.

      • Forward

        public static final SchemaAutoUpdateCompatibilityStrategy Forward
        Messages written in the new schema can be read by the previous schema. To be forward compatible, the new schema must not remove any fields which don't have default values in the previous schema. However, it may add new fields.

      • AlwaysCompatible

        public static final SchemaAutoUpdateCompatibilityStrategy AlwaysCompatible
        Always Compatible - The new schema will not be checked for compatibility against old schemas. In other words, new schemas will always be marked assumed compatible.

      • BackwardTransitive

        public static final SchemaAutoUpdateCompatibilityStrategy BackwardTransitive
        Be similar to Backward. BackwardTransitive ensure all previous version schema can be read by the new schema.

      • ForwardTransitive

        public static final SchemaAutoUpdateCompatibilityStrategy ForwardTransitive
        Be similar to Forward, ForwardTransitive ensure new schema can be ready by all previous version schema.

    • Method Detail

      • values

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

      • valueOf

        public static SchemaAutoUpdateCompatibilityStrategy 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
