    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      AUTO_REFRESH
      if true the graph gets refreshed automatically in periodic intervals.
      CREATE_EDGE_ID_INDEX
      if true, an index is prepared during loading which enables retrieval of edge paths
      CREATE_EDGE_ID_MAPPING
      if true, a mapping is prepared during loading which enables edge key arguments and filters containing edge keys
      CREATE_LABEL_HISTOGRAM
      whether a label histogram needs to be generated when the graph is loaded
      CREATE_VERTEX_ID_INDEX
      if true, an index is prepared during loading which enables retrieval of vertex paths
      CREATE_VERTEX_ID_MAPPING
      if true, a mapping is prepared during loading which enables vertex arguments and vertex filters
      FETCH_INTERVAL_SEC
      (only relevant if the format supports delta updates) the interval in which the graph source is queried for changes
      LOAD_EDGE_LABEL
      whether or not to load the edge label if it is available
      LOAD_VERTEX_LABELS
      whether or not to load the vertex label if it is available
      LOADING_PROGRESS_REPORTING_FREQUENCY
      indicates at what frequency the loading of vertices and edges should be logged.
      PARTITION_DISCARD_DEFAULT_VALUES
      [relevant for partition_while_loading]when partition_while_loading is specified, if set to by_label, the properties that contain only default values are removed from vertex and edge providers.
      PROPERTY_VALUE_DELIMITER
      if null read the whole string value as label.
      SKIP_EDGES
      whether or not to load the edges
      SKIP_VERTICES
      whether or not to load the vertices
      SNAPSHOTS_SOURCE
      source of graph snapshots: if REFRESH, new snapshots can be created only by reading the graph again via this config (e.g., with `readGraphWithProperties`), or equivalently via auto-refresh if enabled; if CHANGE_SET, new snapshots can be added only via changesets by any session.
      STRICT_MODE
      if true, exceptions are thrown and logged with ERROR level whenever loader encounters problems with input file, such as invalid format, repeated keys, missing fields, mismatches and other potential errors.
      UPDATE_INTERVAL_SEC
      the interval in which a new snapshot is created, either by reloading the entire graph or if the format supports delta-updates, out of the cached changes.
      UPDATE_PROPERTIES_IN_PLACE
      if true, non-structural updates get applied to the graph in-place, else non-structural updates also cause new snapshots of the graph to be created.
      UPDATE_THRESHOLD
      (only relevant if the format supports delta updates) the maximum number of changes that are cached before a new snapshot is created.
      USE_VERTEX_PROPERTY_VALUE_AS_LABEL
      load the given property as vertex label.
