Here is the query i am doing g.V().has('type',textContains('car')).inE().has('timestamp',eq('')).inV().valueMap() The documentation says - JanusGraph is intelligent enough to use vertex-centric indices when available.

Does it still traverse through all edges or directly find the edges with empty timestamp ? I assume that Janus can only leverage a vertex centric index, if you specify the label, since that was the case in Titan and I don't think I heard about any changes in this area. So in cases where i need to do lot of traversal, ES is not helpful ? Again, ES is helpful for the initial vertex lookup. Once you start to traverse through the graph, you can only rely on vertex centric indices (or a good model that doesn't require much filtering). Also can you explain a bit more on OLAP query You can read up on OLAP here: http://docs.janusgraph.org/0.2.0-SNAPSHOT/hadoop-tp3.html ...and here: http://tinkerpop.apache.org/docs/current/reference/#_olap_hadoop_gremlin Cheers, Daniel On Thu, Sep 21, 2017 at 7:07 AM, Suny <sahi...@...> wrote: Thanks, All the in edges will have same label.

I have a type attribute on all vertices based on which i can differentiate group of vertices. The query i want to do is :> g.V().has('type',textContains('car')).inE().has('timestamp','').inV().valueMap() I created an index on type attribute. If I just query for :> g.V().has('type',textContains('car')) it is coming back very fast with result. If I add the traversal part it is slowing down. So, JG is using ES to retrieve the vertices of type 'car' and then for traversal it is using just JG. Can I make JG to use ES for traversal too ? If i add index on edge attribute 'timestamp', does this fasten the query ? Thanks -- You received this message because you are subscribed to the Google Groups "JanusGraph users" group.

Is it because for 1st query it gets the result using ES for the second query it gets vertex id's from ES but for getting attributes it needs to hit JG again ?

Also can you explain a bit more on OLAP query You can read up on OLAP here: http://docs.janusgraph.org/0.2.0-SNAPSHOT/hadoop-tp3.html ...and here: http://tinkerpop.apache.org/docs/current/reference/#_olap_hadoop_gremlin Cheers, Daniel On Thu, Sep 21, 2017 at 7:07 AM, Suny <sahi...@...> wrote: Thanks, All the in edges will have same label.

Can I make JG to use ES for traversal too ? ES is only useful for initial / global vertex lookups.

I have a type attribute on all vertices based on which i can differentiate group of vertices. The query i want to do is :> g.V().has('type',textContains('car')).inE().has('timestamp','').inV().valueMap() I created an index on type attribute. If I just query for :> g.V().has('type',textContains('car')) it is coming back very fast with result. If I add the traversal part it is slowing down. So, JG is using ES to retrieve the vertices of type 'car' and then for traversal it is using just JG. Can I make JG to use ES for traversal too ? If i add index on edge attribute 'timestamp', does this fasten the query ? Thanks -- You received this message because you are subscribed to the Google Groups "JanusGraph users" group.

When I do :> g.V().has('type',textContains('site')).valueMap() it is taking so much time to retrieve data. I have 1500 vertices of type car. Is it because for 1st query it gets the result using ES for the second query it gets vertex id's from ES but for getting attributes it needs to hit JG again ? Is there a way to fasten up the second query ?

Custom type Kryo serializers simone...@... #836 I'm running a JanusGraph 0.1 and I need to set a custom class as attribute type. package com.contentwise.janus.test; public class MyClass implements Comparable<MyClass> { private String title; private Integer rank; public MyClass(){ } public MyClass(String title, Integer rank){ this.title = title; this.rank = rank; } public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public Integer getRank() { return rank; } public void setRank(Integer rank) { this.rank = rank; } @Override public int compareTo(MyClass o) { return rank.compareTo(o.rank); } @Override public String toString(){ return "Compless[" + title + ", " + rank + "]"; } } I defined the following Janus serializer package com.contentwise.janus.test; import org.janusgraph.core.attribute.AttributeSerializer; import org.janusgraph.diskstorage.ScanBuffer; import org.janusgraph.diskstorage.WriteBuffer; import org.janusgraph.graphdb.database.serialize.attribute.IntegerSerializer; import org.janusgraph.graphdb.database.serialize.attribute.StringSerializer; public class MyClassSerializer implements AttributeSerializer<MyClass> { private final StringSerializer titleSerializer = new StringSerializer(); private final IntegerSerializer rankSerializer = new IntegerSerializer(); @Override public MyClass read(ScanBuffer buffer) { String title = titleSerializer.read(buffer); Integer rank = rankSerializer.read(buffer); return new MyClass(title, rank); } @Override public void write(WriteBuffer buffer, MyClass attribute) { titleSerializer.write(buffer, attribute.getTitle()); rankSerializer.write(buffer,attribute.getRank()); } } and then added the references in the janus-cassandra-es.properties file (I already defined the serializers for arrays and linkedmaps) attributes.custom.attribute10.attribute-class=java.util.ArrayList attributes.custom.attribute10.serializer-class=com.contentwise.janus.serializer.ArrayListSerializer attributes.custom.attribute11.attribute-class=java.util.LinkedHashMap attributes.custom.attribute11.serializer-class=com.contentwise.janus.serializer.LinkedHashMapSerializer attributes.custom.attribute12.attribute-class=com.contentwise.janus.test.MyClass attributes.custom.attribute12.serializer-class=com.contentwise.janus.test.MyClassSerializer Restarting the graph I was able to create new attributes of type MyClass using the console and I was able to perform some queries, too (ex. order by and filter) :remote connect tinkerpop.server conf/remote.yaml :> g.addV().property("uri", "tst://test") :> g.addV().property("uri", "tst://test/1").property("attr1", "AAA").property("attr2", 3).property("attr3", 2.23f).property("attr4", new com.contentwise.janus.test.MyClass('AAA', 3)).as("source").V().has("uri", "tst://test").addE("instance_of").from("source").outV() :> g.addV().property("uri", "tst://test/2").property("attr1", "BBB").property("attr2", 1).property("attr3", 2.2f).property("attr4", new com.contentwise.janus.test.MyClass('BBB', 1)).as("source").V().has("uri", "tst://test").addE("instance_of").from("source").outV() :> g.V().has("uri", "tst://test").in("instance_of").order().by("attr4", incr).values("attr4") Problems came out performing query from my app (trying both gremlin driver and java GVL).

Re: Janus Solr configuration Jason Plurad <plu...@...> #834 If you have a standalone Cassandra install, you can use cqlsh to drop the keyspace. For example, if you're using the default keyspace name: `$CASSANDRA_HOME/bin/cqlsh -e 'drop keyspace janusgraph'` If you are using Cassandra in the pre-packaged distribution, you can use the clean command on janusgraph.sh `cd $JANUSGRAPH_HOME bin/janusgraph.sh stop bin/janusgraph.sh clean` As you've noticed, Solr 4.3 is not a supported version. You'd be best off the with latest 5.z version. toggle quoted message Show quoted text On Friday, September 22, 2017 at 8:27:04 AM UTC-4, Ankur Goel wrote: Problem resolved: default global value is Cloud, after clearing cassandra it works.

I read the official documents and i'm not clear yet how a cluster is created. As i understood, most of the documents refer to the hbase or Cassandra cluster as the janusgraph cluster. My problem is how can we create a janusgraph/gremlin server cluster? 1) Do i only need to run janusgraph/gremlin servers in the same network so that they will create a cluster automatically? 2) Or is there a way to configure a cluster so that janusgraph instances will communicate with each other? 3) If there is no communication between the janusgraph/gremlin servers can't there be any transaction issues? For example one server adding a new node to a graph and at the same time another server is also adding a node which will make an inconsistency.

Re: ES with JG Jason Plurad <plu...@...> #831 1500 vertices is a fair amount, but how much data is getting returned in the valueMap? Is there a large number of properties in the map or perhaps are the values very large? Very easily could be the cost of serializing that map.

When I do :> g.V().has('type',textContains('site')).valueMap() it is taking so much time to retrieve data. I have 1500 vertices of type car. Is it because for 1st query it gets the result using ES for the second query it gets vertex id's from ES but for getting attributes it needs to hit JG again ? Is there a way to fasten up the second query ?

Re: Using ES for traversal queries ? Jason Plurad <plu...@...> #830 No, explain() doesn't give any clear indication currently whether an index will be utilized. I opened up an issue for that. What counts are you dealing with here? g.V().has('type',textContains('car')).count() g.V().has('type',textContains('car')).inE().count() g.V().has('type',textContains('car')).inE().has('timestamp',eq('')).count() toggle quoted message Show quoted text On Thursday, September 21, 2017 at 1:59:37 PM UTC-4, Suny wrote: I implemented vertex-centric index on edge label. Here is the query i am doing g.V().has('type',textContains('car')).inE().has('timestamp',eq('')).inV().valueMap() The documentation says - JanusGraph is intelligent enough to use vertex-centric indices when available.

Does it still traverse through all edges or directly find the edges with empty timestamp ? I assume that Janus can only leverage a vertex centric index, if you specify the label, since that was the case in Titan and I don't think I heard about any changes in this area. So in cases where i need to do lot of traversal, ES is not helpful ? Again, ES is helpful for the initial vertex lookup. Once you start to traverse through the graph, you can only rely on vertex centric indices (or a good model that doesn't require much filtering). Also can you explain a bit more on OLAP query You can read up on OLAP here: http://docs.janusgraph.org/0.2.0-SNAPSHOT/hadoop-tp3.html ...and here: http://tinkerpop.apache.org/docs/current/reference/#_olap_hadoop_gremlin Cheers, Daniel On Thu, Sep 21, 2017 at 7:07 AM, Suny <sahi...@...> wrote: Thanks, All the in edges will have same label.

If I just query for :> g.V().has('type',textContains('car')) it is coming back very fast with result. If I add the traversal part it is slowing down.

Re: Creating a janusgraph cluster Dilan Ranasinghe <dila...@...> #824 Thanks. There is a confusion for me with your explanation and the section http://docs.janusgraph.org/0.1.0/failure-recovery.html#_janusgraph_instance_failure . There it says "However, some schema related operations - such as installing indexes - require the coordination of all JanusGraph instances". If servers don't communicate with each other, is this coordination is achieved through the underline back-end (hBase)?

However, they can be clustered for example for load balancing. For your data consistency questions, you should read the documentation with special attention to hbase and data consistency. But one that may be overlooked is the ID allocation options - http://docs.janusgraph.org/latest/config-ref.html#_ids If there is something that the documentation doesn't address let us know what should be enhanced.

I read the official documents and i'm not clear yet how a cluster is created. As i understood, most of the documents refer to the hbase or Cassandra cluster as the janusgraph cluster. My problem is how can we create a janusgraph/gremlin server cluster? 1) Do i only need to run janusgraph/gremlin servers in the same network so that they will create a cluster automatically? 2) Or is there a way to configure a cluster so that janusgraph instances will communicate with each other? 3) If there is no communication between the janusgraph/gremlin servers can't there be any transaction issues? For example one server adding a new node to a graph and at the same time another server is also adding a node which will make an inconsistency.
