creating multiple properties on a node using batch inserter

[John Fry]

Hi All,

when using the batch inserter java code below the property "name" doesn't appear on the node when I check it via a Cypher query.

The property "aka" does however appear on the node. If i don't add the "aka" property then the "name" property appears.

I have been scratching me head on this for a while now - I can't seem to create both "name" and "aka" properties.

Thanks for any help, John,

inserter.createDeferredSchemaIndex(MyLabel.Person).on("name").create();

...........

Map<String, Object> propertyName = new HashMap<String, Object>();

propertyName.put("name", nd.name);

long nodeId = -1;   

nodeId = inserter.createNode(propertyName, MyLabel.Person);

String[] aka = new String[nd.akaNames.size()];

aka = nd.akaNames.toArray(aka);        

Map<String, Object> propertyAka = new HashMap<String, Object>();

propertyAka.put("aka", aka);

inserter.setNodeProperties(nodeId, propertyAka);

here is what cypher returns

START a=node(4238335)

> return keys(a);

+---------+

| keys(a) |

+---------+

| ["aka"] |

+---------+

1 row

setNodeProperties overrides all properties

so the map you use there has to contain all the properties you want to have on your node

I see - thanks Michael.

According to the docs i should be able to do this a mix object that are strings or arrays of strings. Does this seem safe/reasonable?

String[] aka = new String[nd.akaNames.size()];

aka = nd.akaNames.toArray(aka);  

Map<String, Object> property = new HashMap<String, Object>();

property.put("name", nd.name);      

property.put("aka", aka);

long nodeId = -1;   

nodeId = inserter.createNode(property, MyLabel.Person);

Yes, that's totally doable

Tested and working - thank you.
