Je vais intégrer mon application Neo4j avec Elasticsearch. Je vais essayer le plugin Neo4j suivant de GraphAware https://github.com/graphaware/neo4j-to-elasticsearchNeo4j 3.1.3 avec l'intégration d'Elasticsearch
Pourriez-vous dire s'il supporte la version Neo4j 3.1.3? Aussi, quelle version d'ES devrait être utilisée là? Supporte-t-il ES 5.3.0 par exemple?
À l'heure actuelle, j'ai installé Elasticsearch 5.3.0 localement. Aussi j'ai ajouté 2 pots:
graphaware-neo4j-to-elasticsearch-3.1.3.45.7.jar
graphaware-server-community-all-3.1.3.46.jar
à mon dossier Neo4j CE 3.1.3\plugins\.
Aussi, j'ai ajouté la configuration suivante (comme descrbed ici https://github.com/neo4j-contrib/neo4j-elasticsearch#example) lignes dans ma configuration de base de données (Neo4j Community Edition\neo4j.conf):
elasticsearch.host_name=http://localhost:9200
elasticsearch.index_spec=decisions:Decision(name,description)
Mais quand je l'insertion des données par rien du projet de printemps de données Neo4j arrive. Les index Elasticsearch sont toujours vides.
Qu'est-ce que je fais mal et comment le faire fonctionner?
MISE À JOUR
J'ai fait quelques progrès sur ce point:
Ceci est mon Neo4j.conf:
dbms.unmanaged_extension_classes=com.graphaware.server=/graphaware
com.graphaware.runtime.enabled=true
com.graphaware.module.ES.2=com.graphaware.module.es.ElasticSearchModuleBootstrapper
com.graphaware.module.UIDM.uuidProperty=ID()
com.graphaware.module.ES.node=hasLabel('Decision')
com.graphaware.module.ES.relationship=(false)
com.graphaware.module.ES.uri=localhost
com.graphaware.module.ES.port=9200
com.graphaware.module.ES.index=neo4j-index
Dans ma demande, j'ai une entité: Decision. Decision est un type complexe avec une grande hiérarchie parent:
Decision extends Commentable extends Votable extends Flaggable ... and so on.
En ce moment je suis d'ajouter ~ 60 noeuds de décision à ma base de données Neo4j mais je suis incapable de voir tous à ES. Je ne peux voir que le premier avec une duplication par classe parente dans la hiérarchie.
Ce que ce que j'ai maintenant:
$ curl -XGET 'http://127.0.0.1:9200/neo4j-index-node/_search?pretty=true&q=*:*'

Pourquoi tous les sous-classes de la décision (comme Votable, Likeable) y sont également dupliqués? Comme vous pouvez le voir dans ma config j'ai essayé d'exclure tout sauf:
com.graphaware.module.ES.node=hasLabel('Decision')
Mon but est d'indexer uniquement Decision noeuds à ES.
Aussi, pourquoi la seule décision unique de ~ 60 est-elle indexée là? Je pense que "_id": "null" à la sortie Elasticsearch JSON est lié à ce problème. Qu'est-ce que je fais mal ?
