Constructor Detail

OracleDataLoaderConfig

public OracleDataLoaderConfig()

Creates a new OracleDataLoader config object with default configuration settings.

Method Detail

getDirOrSqlldrPath

public java.lang.String getDirOrSqlldrPath()

Gets the database directory or SQL loader path to use for parallel data loading. If loading uses external tables, this parameter specifies the database directory where the graph files will be written into in order to be loaded using external tables. For loading using SQL loader, this parameter specifies the path where the sqlldr utility is located

getInstance

public static OracleDataLoaderConfig getInstance()

Create an OracleDataLoaderConfig with the default settings.

getInstance

public static OracleDataLoaderConfig getInstance(long lVertexSrcOffsetlines,
                                                 long lEdgeSrcOffsetlines,
                                                 long lVertexSrcMaxlines,
                                                 long lEdgeSrcMaxlines,
                                                 long lVertexIDOffset,
                                                 long lEdgeIDOffset,
                                                 int iDop,
                                                 int iPartitions,
                                                 int iOffset,
                                                 DataLoaderListener dll,
                                                 OraclePropertyGraphDataLoader.SPLITTER_TYPE splitterFlag,
                                                 java.lang.String szPrefix,
                                                 java.lang.String szDirOrSqlldrPath,
                                                 boolean bRebuildIndex,
                                                 java.lang.String szTbs,
                                                 java.lang.String szOptions)

Creates a new OracleDataLoader config object .

Parameters:

lVertexSrcOffsetlines - the line offset of vertices. Loading vertices after the offset. Default is 0.

lEdgeSrcOffsetlines - the line offset of edges. Loading edges after the offset. Default is 0.

lVertexSrcMaxlines - the max lines of vertices to be loaded. Default is -1 (i.e., load all vertices)

lEdgeSrcMaxlines - the max lines of edges to be loaded. Default is -1 (i.e., load all edges)

lVertexIDOffset - the offset of vertex ID. That is, the vertex ID would be vertexID+lVertexIDOffset. Default is 0

lEdgeIDOffset - the offset of edge ID. That is, the edge ID would be edgeID+lEdgeIDOffset. Default is 0

iDop - degree of parallelism. It has to be a positive integer.

iPartitions - number of partitions (i.e., data loading clients)

iOffset - offset of partitions. It is from 0 to iPartitions-1

dll - a DataLoaderListener object.

splitterFlag - the flag to set splitting: REGULARFILE, NAMEDPIPE, PIPEDSTREAM. Default value is REGULARFILE

szPrefix - the prefix used to generate splitted files for regular file or named pipe based splitting

szDirOrSqlldrPath - the database directory for external table based loading or the path to sqlldr

bRebuildIndex - setting the flag to true would disable indexes/constraints on the tables before loading data into the tables, and enable indexes/contraints on the tables after loading data into the tables

szTbs - tablespace name

szOptions - the extra options
