java code that i am using for data uploading: { int loopCounter = getTotalNoofRecorsdCountFromDB(); List<Data> data = getData fromDB(); JanusGraphTransaction tx = graph.newTransaction(); for (int i = 0; i < loopCounter; i++) { VerticesDTO vertex = data.get(i); Vertex v = tx.addVertex(T.label, "data", dataid, vertex.getDataId()); v.property("vlabel", "taglead"); v.property("prop1", vertex.getProp1()); v.property("prop2", vertex.getProp2()); v.property("prop3", vertex.getProp3()); v.property("prop4", vertex.getProp4()); v.property("prop5", vertex.getProp5()); v.property("prop6", vertex.getProp6()); v.property("prop7", vertex.getProp7()); List<String> prop8 = getProp8(); prop8.forEach(p -> v.property("prop8", p)); List<String> prop9 = getProp9(); prop9.forEach(p -> v.property("prop9", p)); List<String> prop10 = getProp10(); prop10.forEach(p -> v.property("prop10", p)); if(i%1000 ==0){ tx.commit(); } } tx.commit(); } Please suggest. ~AnkurG On Tuesday, September 26, 2017 at 11:05:28 AM UTC+5:30, Ankur Goel wrote:

http://docs.janusgraph.org/latest/config-ref.html#_ids I'd suggest trying to increase the ids.block-size, and perhaps adjusting the ids.renew-percentage. No idea what your graph loading code looks like, but you might want to commit() transactions in smaller batches. Also check out http://tinkerpop.apache.org/docs/current/tutorials/getting-started/#_loading_data On Tuesday, September 26, 2017 at 1:35:28 AM UTC-4, Ankur Goel wrote:

Hi, i have connected Janus to cassandra cluster: storage.hostname=x.x.x.1,x.x.x.2,x.x.x.3 ids.block-size=10000 storage.batch-loading=true storage.lock.wait-time=9000 storage.cassandra.read-consistency-level=ONE storage.cassandra.write-consistency-level=ALL query.force-index=false storage.connection-timeout=60000
storage.lock.retries=10 i am inserting vertex in large no through java code: getting below exception: 2017-09-26 10:55:05,577 WARN [JanusGraphID(4)(3)[0]] org.janusgraph.diskstorage.idmanagement.ConsistentKeyIDAuthority: Temporary storage exception while acquiring id block - retrying in PT0.6S: {} org.janusgraph.diskstorage.TemporaryBackendException: Wrote claim for id block [1, 80001) in PT0.324S => too slow, threshold is: PT0.3S at org.janusgraph.diskstorage.idmanagement.ConsistentKeyIDAuthority.getIDBlock(ConsistentKeyIDAuthority.java:276) at org.janusgraph.graphdb.database.idassigner.StandardIDPool$IDBlockGetter.call(StandardIDPool.java:288) at org.janusgraph.graphdb.database.idassigner.StandardIDPool$IDBlockGetter.call(StandardIDPool.java:255) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
