ArangoDB: Java: Create multiple documents

ArangoCollection interface provides 'insertDocument' method  which can take a colleciton of input documents and create them in one call.

 

Signature

<T> MultiDocumentEntity<DocumentCreateEntity<T>> insertDocuments(Collection<T> values) throws ArangoDBException;
<T> MultiDocumentEntity<DocumentCreateEntity<T>> insertDocuments(Collection<T> values, DocumentCreateOptions options) throws ArangoDBException;

 

You can provides additional options like waitForSync, overwrite, returnNew, returnOld etc., using DocumentCreateOptions.

 

Example

MultiDocumentEntity<DocumentCreateEntity<BaseDocument>> persistedDocs = collection.insertDocuments(Arrays.asList(empDocument1, empDocument2), docOptions);

Find the below working application.

		Collection<DocumentCreateEntity<BaseDocument>> docs = persistedDocs.getDocuments();

		for (DocumentCreateEntity<BaseDocument> doc : docs) {
			System.out.println("\n");
			System.out.println("id : " + doc.getId());
			System.out.println("key : " + doc.getKey());
			System.out.println("rev : " + doc.getRev());
			System.out.println("doc : " + doc.getNew());
		}

		// Dropping the collection and database
		collection.drop();
		arangoDatabase.drop();
		System.exit(0);
	}
}

Output
