Hi, I have configured batch loading (storage.batch-loading=true,schema.default = none,ids.block-size=100000). While importing data, I get the following exception :
java.lang.IllegalArgumentException: Property Key with given name does not exist: createdAt at org.janusgraph.graphdb.types.typemaker.DisableDefaultSchemaMaker.makePropertyKey(DisableDefaultSchemaMaker.java:46) at org.janusgraph.core.schema.DefaultSchemaMaker.makePropertyKey(DefaultSchemaMaker.java:73) at org.janusgraph.graphdb.transaction.StandardJanusGraphTx.getOrCreatePropertyKey(StandardJanusGraphTx.java:936) at org.janusgraph.graphdb.vertices.AbstractVertex.property(AbstractVertex.java:148) at org.janusgraph.core.JanusGraphVertex.property(JanusGraphVertex.java:72) at org.janusgraph.graphdb.util.ElementHelper.attachProperties(ElementHelper.java:80) at org.janusgraph.graphdb.tinkerpop.JanusGraphBlueprintsTransaction.addVertex(JanusGraphBlueprintsTransaction.java:124) at com.fujitsu.fnc.mlpce.tetopology.impl.GraphDBService.addVertex(GraphDBService.java:398) at com.fujitsu.fnc.mlpce.tetopology.impl.TeTopologyImpl.createNode(TeTopologyImpl.java:408) at com.fujitsu.fnc.mlpce.tetopology.impl.GraphTransactionWrapper.createNode(GraphTransactionWrapper.java:30) at com.fujitsu.fnc.mlpce.topology.mgr.impl.metaengine.WDMMetaEngineImpl.buildGDBNodes(WDMMetaEngineImpl.java:511) at com.fujitsu.fnc.mlpce.topology.mgr.impl.metaengine.WDMMetaEngineImplResyncWorker.call(WDMMetaEngineImplResyncWorker.java:43) at com.fujitsu.fnc.mlpce.topology.mgr.impl.metaengine.WDMMetaEngineImplResyncWorker.call(WDMMetaEngineImplResyncWorker.java:18) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748). And due to this, the total number of vertices and edges populated are lesser than it supposed to be. Why do we get this exception only in batch loading and any suggestions to resolve? |

Hi Suriya, See https://docs.janusgraph.org/basics/configuration-reference/#schema and https://docs.janusgraph.org/basics/schema/#defining-property-keys schema.default=none means property keys are not automatically created in the schema. You first have to add the createdAt property to the schema or choose a different schema option. HTH, Marc Hi, I have configured batch loading (storage.batch-loading=true, |

Hi,
Notice that you cannot use automatic schema creation feature and storage.batch-loading=true. If you enable storage.batch-loading than automatic schema creation feature disables. So, either disable storage.batch-loading or don't use automatic schema creation (explicitly define your schema). Best regards, Oleksandr |
