graph_name	Yes	String	Graph name

Request Parameters

Table 2 Request body parameters
Parameter	Mandatory	Type	Description
edgesetPath	No	String	Edge file directory or name
edgesetFormat	No	String	Format of the edge data set. Currently, only the CSV format is supported. The CSV format is used by default.
vertexsetPath	No	String	Vertex file directory or name
vertexsetFormat	No	String	Format of the vertex data set. Currently, only the CSV format is supported. The CSV format is used by default.
schemaPath	No	String	OBS path of the metadata file of the new data
logDir	No	String	Directory for storing logs of imported graphs. This directory stores the data that fails to be imported during graph creation and detailed error causes.
parallelEdge	No	Object	How to process repetitive edges.
action	No	String	Processing mode of repetitive edges. The value can be allow, ignore, or override. The default value is allow. allow indicates that repetitive edges are allowed. ignore indicates that subsequent repetitive edges are ignored. override indicates that the previous repetitive edges are overwritten.
ignoreLabel	No	Boolean	Whether to ignore labels on repetitive edges. The value is true or false, and the default value is true. true: Indicates that the repetitive edge definition does not contain the label. That is, the <source vertex, target vertex> indicates an edge, excluding the label information. false: Indicates that the repetitive edge definition contains the label. That is, the <source vertex, target vertex, label> indicates an edge.
delimiter	No	Character	Field separator in a CSV file. The default value is comma (,). The default element separator in a field of the list/set type is semicolon (;).
trimQuote	No	Character	Field quote character in a CSV file. The default value is double quotation marks ("). They are used to enclose a field if the field contains separators or line breaks.
offline	No	Boolean	Whether offline import is selected. The value is true or false, and the default value is false. true: Offline import is selected. The import speed is high, but the graph is locked and cannot be read or written during the import. false: Online import is selected. Compared with offline import, online import is slower. However, the graph can be read (cannot be written) during the import.
obsParameters	Yes	Object	OBS parameters

Table 3 obsParameters parameters
Parameter	Mandatory	Type	Description
accessKey	Yes	String	User AK
secretKey	Yes	String	User SK

Response Parameters

Table 4 Response body parameters
Parameter	Type	Description

errorCode	String	System prompt code. If execution succeeds, this parameter may be left blank. If execution fails, this parameter is used to display the error code.
jobId	String	ID of an asynchronous job You can view the job execution status and obtain the return result by querying the job ID. For details, see Job Management APIs.
