createDeferredSchemaIndex

public IndexCreator createDeferredSchemaIndex(Label label)

Description copied from interface: BatchInserter

Returns an IndexCreator where details about the index to create can be specified. When all details have been entered create must be called for it to actually be created. Creating an index enables indexing for nodes with the specified label. The index will have the details supplied to the returned index creator. Indexes created with the method are deferred until the batch inserter is shut down, at which point a background job will populate all indexes, i.e. the index is not available during the batch insertion itself. It is therefore advisable to create deferred indexes just before shutting down the batch inserter.

Specified by:

createDeferredSchemaIndex in interface BatchInserter

Parameters:

label - label on nodes to be indexed

Returns:

an IndexCreator capable of providing details for, as well as creating an index for the given label.

createDeferredConstraint

public ConstraintCreator createDeferredConstraint(Label label)

Description copied from interface: BatchInserter

Returns a ConstraintCreator where details about the constraint can be specified. When all details have been entered ConstraintCreator.create() must be called for it to actually be created. Creating a constraint will have the transaction creating it block on commit until all existing data has been verified for compliance. If any existing data doesn't comply with the constraint the transaction will not be able to commit, but fail in Transaction.close().

Specified by:

createDeferredConstraint in interface BatchInserter

Parameters:

label - the label this constraint is for.

Returns:

a ConstraintCreator capable of providing details for, as well as creating a constraint for the given label.

createNode

Specified by:

createNode in interface BatchInserter

Parameters:

createNode

public void createNode(long id,
              Map<String,Object> properties,

Specified by:

createNode in interface BatchInserter

Parameters:

id - the id of the node to create.

properties - map containing properties or null if no properties should be added.

setNodeProperties

public void setNodeProperties(long node,
                     Map<String,Object> properties)

Description copied from interface: BatchInserter

Sets the properties of a node. This method will remove any properties already existing and replace it with properties in the supplied map.

For best performance try supply all the nodes properties upon creation of the node. This method will delete any existing properties so using it together with BatchInserter.getNodeProperties(long) will have bad performance.

Sets the properties of a relationship. This method will remove any properties already existing and replace it with properties in the supplied map.

For best performance try supply all the relationship properties upon creation of the relationship. This method will delete any existing properties so using it together with BatchInserter.getRelationshipProperties(long) will have bad performance.

Specified by:

setRelationshipProperties in interface BatchInserter

Parameters:

After this method has been invoked any other method call to this batch inserter is illegal.

Specified by:

shutdown in interface BatchInserter
