    • METADATA_NO_FALLBACK

      public static final Cluster.LbSubsetConfig.LbSubsetMetadataFallbackPolicy METADATA_NO_FALLBACK
       No fallback. Route metadata will be used as-is.
       
      METADATA_NO_FALLBACK = 0;
    • FALLBACK_LIST

      public static final Cluster.LbSubsetConfig.LbSubsetMetadataFallbackPolicy FALLBACK_LIST
       A special metadata key ``fallback_list`` will be used to provide variants of metadata to try.
       Value of ``fallback_list`` key has to be a list. Every list element has to be a struct - it will
       be merged with route metadata, overriding keys that appear in both places.
       ``fallback_list`` entries will be used in order until a host is found.
      
       ``fallback_list`` key itself is removed from metadata before subset load balancing is performed.
      
       Example:
      
       for metadata:
      
       .. code-block:: yaml
      
       version: 1.0
       fallback_list:
       - version: 2.0
       hardware: c64
       - hardware: c32
       - version: 3.0
      
       at first, metadata:
      
       .. code-block:: json
      
       {"version": "2.0", "hardware": "c64"}
      
       will be used for load balancing. If no host is found, metadata:
      
       .. code-block:: json
      
       {"version": "1.0", "hardware": "c32"}
      
       is next to try. If it still results in no host, finally metadata:
      
       .. code-block:: json
      
       {"version": "3.0"}
      
       is used.
