      • TYPE

        public static final GraphPropertyConfig.Field TYPE
        type of property (Note: date is deprecated, use one of local_date / time / timestamp / time_with_timezone / timestamp_with_timezone instead). vertex/edge are place-holders for the type specified in vertex_id_type/edge_id_type fields.
      • DEFAULT

        public static final GraphPropertyConfig.Field DEFAULT
        default value to be assigned to this property if datasource does not provide it. In case of date type: string is expected to be formatted with yyyy-MM-dd HH:mm:ss. If no default is present (null), non-existent properties will contain default Java types (primitives) or empty string (string) or 01.01.1970 00:00 (date).
      • COLUMN

        public static final GraphPropertyConfig.Field COLUMN
        name or index (starting from 1) of the column holding the property data. If it is not specified, the loader will try to use the property name as column name (for CSV format only)
      • STORES

        public static final GraphPropertyConfig.Field STORES
        A list of storage identifiers that indicate where this property resides.
      • MAX_DISTINCT_STRINGS_PER_POOL

        public static final GraphPropertyConfig.Field MAX_DISTINCT_STRINGS_PER_POOL
        [only relevant if string_pooling_strategy is indexed] amount of distinct strings per property after which to stop pooling. If the limit is reached an exception is thrown. If set to null, the default value from the global PGX configuration will be used.
      • STRING_POOLING_STRATEGY

        public static final GraphPropertyConfig.Field STRING_POOLING_STRATEGY
        which string pooling strategy to use. If set to null, the default value from the global PGX configuration will be used.
      • AGGREGATE

        public static final GraphPropertyConfig.Field AGGREGATE

Field names containing dots are possible, in this case the dots need to be escaped using backslashes to resolve ambiguities. Only the exactly specified object are loaded, if they are non existent, the default value is used
      • GROUP_KEY

        public static final GraphPropertyConfig.Field GROUP_KEY
        [currently unsupported] can only be used if the property / key is part of the grouping expression
      • DROP_AFTER_LOADING

        public static final GraphPropertyConfig.Field DROP_AFTER_LOADING
