public static enum GraphLoadingConfig.Field extends java.lang.Enum<GraphLoadingConfig.Field> implements ConfigField
Enum Constant and 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_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
|
FILTER
if not
null , load subgraph specified by this filter |
FILTER_STRATEGY
the strategy to process the filter
|
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
|
PROPERTY_VALUE_DELIMITER
(only relevant for
use_vertex_property_value_as_label ) if null read the whole property value as label. |
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_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.
