Bulk insert of a massive graph

[Nicolas]

Hi everybody,

We have a text file which represents the edges of a graph.
For example :
id1 id2
id2 id3
id3 id1
That means that there is an oriented edge from the vertex id1 to
the vertex id2, from the vertex id2 to the vertex id3 and from the
vertex id3 to the vertex id1.
This file size is about 38GB, it's about 50millions vertices and
2B edges.

What is the best way to load and store this graph in GraphDB ?
I red that there may be a way by inserting a JSon file using
Gremlin console but I'm not sure that it can work.

Thanks a lot.
Nicolas

Hi,

you could transform it in GraphML format and use this to import:

OrientGraph g = new OrientGraph(dbURL);

GraphMLReader.inputGraph(g, new FileInputStream(inputFile), 100000, null, null, null);

g.shutdown();

An example is this: https://raw.github.com/tinkerpop/gremlin/master/data/graph-example-2.xml

Slightly unrelated, but what would be the fastest/most efficient way of importing such a large quantity of graph data as this is something I'll need to be doing on a regular basis myself soon (I will be running hadoop jobs to generate graphs and importing these into OrientDB).

[Daniel Kersten]

I should also add that I can use the Java API for my imports (ie it does not need to be remote).

Hi,

Blueprints 2.0 has a BatchGraph wrapper:

https://github.com/tinkerpop/blueprints/wiki/Batch-Implementation

Blueprints is part of TinkerPop 2.0 stack which will be released tomorrow.

HTH,

Pierre

ps: Luca, does OrientDB provide a native Batch importer mechanism?

[Nicolas]

Hi everybody,

Thanks for all your answers which are really relevant. It will be
very helpful for us.
I will try both the solutions with XML and BatchGraph wrapper
today.

Hi,

there isn't a batch importer but just some recommendations to improve performance:

• don't use transactions
• turn off the cache

Look at: http://code.google.com/p/orient/wiki/PerformanceTuning#Massive_Insertion

Hi Luca,

By executing the piece of code you gave me, I have a big exception
stack that I don't succeed in interpretating. Have you any ideas of
what may be the problem ? Thanks.

It seems to be a memory problem or somtehing like that because it
works when I try to import a short file (10kB)...

Hi,

you have to reduce the transaction size, or better, totally remove the transactions on import.

Lvc@

[seralf]

wow, this seems really interesting, i need to check it! thanks :-)

[Nicolas]

Dear Luca,

Thanks for your answer.
I tried to remove the transactions by adding
"OGlobalConfiguration.BLUEPRINTS_TX_MODE.setValue(1);" or "-
Dblueprints.graph.txMode=1" as a JVM parameter but it still doen't
work.
Specifying that the mode is manual seems to be unsufficient.
What is the way to remove the transactions on import ?

Nicolas

Hi Nicolas,

starting from TinkerPop 2.0.0 the buffer has been removed in favor of BatchGraph: https://github.com/tinkerpop/blueprints/wiki/Batch-Implementation

Hi Luca,

So I moved to BatchGraph.
I have still the same problem, I don't succes in disabling
transactions :

Here is my code, I read a file with each line like that : "id1 id2"
which means that there is an edge between the vertex id1 and the

Hi,

that message is the fruit of a timeout: the timeout triggers out and dirty data remains in the socket. Can you bulk load records using the local protocol? This would improve A LOT the insertion.

Or you could run locally and run the server as embedded: http://code.google.com/p/orient/wiki/EmbeddedServer

This is a very powerful way to achieve super high speed and let the database to being used outside the JVM with Studio, console or external clients. Soon a new WiKi page about the all the available architectures with OrientDB with PRO/CONS.

Lvc@

[Nicolas]

Okay,
Yes, it's a better idea to use local protocol. Because, what I want to
do is only : bulk load fast and use gremlin console to query and
update the graph in local.

However, by using the local protocol :
Graph g = new OrientGraph("local:/home/nicolas/orienttest");
BatchGraph<OrientGraph> bg = BatchGraph.wrap(g, 10000);
Bulk load is still really slow... As you can see in one of my
precedent post, I read a file to load my graph. My file is about 38GB.
And now, to read an 50MB files, i need about 15 to 20 minutes.

What do i do wrong ? Is there a better way to bulk load in a local way
than the batchgraph ?

Hi,

the first thing is to enable the massive insert intent. Execute this just after opening the graph:

graph.getRawGraph().declareIntent( new OIntentMassiveInsert() );

Then is to disable transactions, but until the TinkerPop fix is ready you will go slowly.

Lvc@

[Marko Rodriguez]

Hi,

Then is to disable transactions, but until the TinkerPop fix is ready you will go slowly.

What fix are you talking about? Again, TransactionalGraph is just start/stopTransactions -- there is no notion of "transaction buffer." The best way to do things is in more big transaction ala:

long counter = 0;

while(...) {

// insert some data

if(++counter % 1000 == 0)

g.stopTransaction(SUCCESS);

}

Thanks,

Marko.

[Nicolas]

Hi,

Okay, with your method Marko and the line you gave me and that I
added Luca, it seems to work correctly and faster.
However, even if it's faster, to load 38GB, I will need a week.

So, if TransactionalGraph is just start/stop Transactions Marko,
is there a way to do bulk insert disabling transactions ?
I use the BatchGraph class to load data into Neo4j too and it's
the same matter.

Thanks a lot for your help,
Nico

[Luca Garulli]

Hi,

I followed the Marko's suggestion to provide a brand new ad-hoc implementation for batch inserts. It's identical to OrientGraph but:

• doesn't implement TransactionalGraph
• uses the Massive Insert intent

If you want to try it get this fork:

Hi Luca,

I just merged your code and added an OrientBatchGraphTest for only test suites that do NOT remove elements. As such, they pass. For those test suites that check the removing of elements, OrientBatchGraphTest fails -- is this correct? OrientBatchGraph is for insertion only?

Thanks Luca -- I appreciate the new feature.

Hi Luca,

   I tested the OrientBatchGraph but I don't succeed in running my program without exception.

   Here is my code : 

   OrientBatchGraph g = new OrientBatchGraph("local:/home/nicolas/Recherche/OrientDb/testdb");

BufferedReader buff = new BufferedReader(new FileReader("/home/nicolas/Recherche/file"));

String line="";

int left, right;

Vertex v1, v2;

String[] t;

while ((line = buff.readLine()) != null) {

t = line.split(" ");

left = Integer.parseInt(t[0]);

right = Integer.parseInt(t[1]);

v1 = g.getVertex(left);

v2=g.getVertex(right);

if (v1 == null) {

g.addVertex(left);

v1=g.getVertex(left);

}

if (v2 == null) {

g.addVertex(right);

v2=g.getVertex(right);

}

g.addEdge(left+"to"+right, v1, v2, "f");

}

g.shutdown();

buff.close();

The error is that when "g.addEdge(left+"to"+right, v1, v2, "f");" is executed, v1 and v2 are null. Do i use "getVertex" correctly ?

Thanks again ;)

Hi,

I didn't succeed in making it work with the 1.0.2-Snapshot. It didn't work neither with the 1.1 Snapshot.

I tried another way using a server with a lot of RAM : 64GB memory.
I used the OGraphDatabase to design my graph.
The loading is made in two phases :
-Firstly, I load the vertices in the database and I keep in a HashMap matching between the idTwitter and the vertex I loaded
-Secondly, I load the edges by using the HashMap to create the edges between the vertices representing the idTwitter.

During the load of the vertices, the RAM usage grows fast and then stops at 28GB and nothing seems to happen. Is there a RAM limitation in the OrientDB config ?

[Luca Garulli]

Hi,

the 1.0.2-Snapshot is quite old: it has been renamed 1.1.0-SNAPSHOT since 1-2 months.

Please use the 1.1.0-SNAPSHOT.

About your use case what is the JVM's heap? Are you following the suggestion in http://code.google.com/p/orient/wiki/PerformanceTuning ?

Hi,

how many vertices and edges are you loading?

First suggestion: keep in memory only the RID, not the entire ODocument:

HashMap<Integer, ORID> map = new HashMap<Integer, ORID>();

...

map.put(left, v.getIdentity());

...
v1 = (ODocument) map.get(left).getRecord();
...
v2 = (ODocument) map.get(right).getRecord();

...

Hi, 

Thanks for your quick answer. We are trying to load about 50 million vertices and 2 billion arcs. 

Your first suggestion improved the load of the vertices, however now the edges are loading 

really slowly (something like 100000 every 10 minutes...) 

Is there a way to speed up this insertion? (maybe with an index on the vertices or something?) 

[Luca Garulli]

You should know if the most of the time is spent on:

1. retrieve of the vertices. Fast solutions:
1. then create an index against the vertex's idTwitter field and remove the hashmap. This will reduce the memory used = less GC but the index will be always slower than a map in memory...
2. or don't use the massive insert = let to OrientDB to use the 2level cache. This could improve a lot if you've a lot of memory but it's not so distant by your initial solution to keep all the vertexes in memory inside a HashMap
2. save the vertex: this could be due to the auto-defragmentation of the underlying storage layer (works exactly like a file system). Fast solutions:
1. wait for the 1.2.0-SNAPSHOT that will improve this
2. or in the meanwhile enlarge the size occupied by the vertex in the storage by using the oversize. "OGraphVertex" class has 2 as factor of oversize but if you've many edges probably you could enlarge a bit and avoid on using the Tree to handle edge set... more on this in another email if this is the problem

Lvc@

[anthony]

So, I've tried looking into the first point by removing the use of massive insert. 

This has drastically reduced the speed of vertices insertion: it has inserted about 20 million 

vertices pretty fast, but won't insert another million (i have waited about an hour before posting). 

The memory stopped growing, like if the script was frozen.

Actually, when I first did the test inserting all vertices and then trying to add edges, the memory use 

was about 50% (we have 64 Go available). Like you said, this probably means that adding an index will not solve the problem, 

since retrieving the vertices should be done quite fast with the hashmap. 

So maybe the issue is located at the second point you mentioned? 

For some deadlines reasons, it would be so nice if we could load the graph before early august, so 

if the other solution is not too long to explain, I would be glad to read it :-)

[Luca Garulli]

Hi,

First: 2Billions of edges in 50millions of edges means that each vertex has about 40 edges. Are they equally distributed (or close to be equal) or are there some super-nodes that has many of them?

Second: you can have much more memory than 64Gb, but the bottleneneck with JVM is the number of old-gen objects that make the GC run too much time. Unfortunately we don't have a off-heap cache yet (it's planned). So the best strategy could be to keep only the RID in memory and lazy loads the ODocument when you create edges.

If you use your HashMap disable the cache (or just use the massive insert intent) or try to remove it in favor of keep ORIDs only and use the OrientDB cache.

To improve the edge creation, if you've about 40 edges per vertex, is to avoid the automatic upgrading for Set<Edge> by reducing the threshold.

Try to set this before any operation against OrientDB:

OGobalCOnfiguration.MVRBTREE_RID_BINARY_THRESHOLD.setValue(-1);

and then try with:

OGobalCOnfiguration.MVRBTREE_RID_BINARY_THRESHOLD.setValue(1);

The first disable the creation of a Tree to handle the edges, while in the second one always use a tree.

[anthony]

Hi, 

Unfortunately, no, the degrees are not equally distributed. The graph is power-law, so we have a few vertices with very high degree (up to 3 millions) and a lot of vertices with very small degree. 

I have tried the following: keeping the massive insert for the vertices (this is definitely needed), and removing it for the edges. This improved the speed of insertion a bit, but still remains quite slow (something like 1 million in 10 minutes). 

I have also tried both the configurations you suggested, and it seems that the insertion is faster when the tree is disabled (maybe this comes from the high degree vertices?). 

Just to be clear on what I'm doing right now, I preserve the ORIDs in a Hashmap, and then use it to create the edges (this is something you adviced previously). If I follow you correctly, there is a way to keep ORIDs in the OrientDB cache and then avoid the use of the hashmap?

Again, thanks for your help and quick answers :)

Anthony 

[Luca Garulli]

Hi Antony,

release 1.2 will have the defragmentation queue, so on massive insert and update (when you create edges consider as a massive insert+update!) will speed up a lot, but this is not yet available.

If you remove your HashMap you should create an index against the idTwitter attribute but this would slow down the insertion but saving memory. Since this is not your case (you've plenty of memory) using the HashMap could help.

Another small hint: disable the multi-threading if you've a single thread:

OGlobalConfiguration.ENVIRONMENT_CONCURRENT.setValue( false );

[Milen Dyankov]

Hi guys,

sorry for jumping in the middle of your discussion but I'm experiencing similar problem and it seams I managed to optimize it a bit. I'm inserting about 1M vertexes and about 1.5M edges like this (pseudo code):

foreach (vertexDef) {

 insert vertex_N in DB

 put RID_N in cache

}

...

foreach (edgeDef) {

 insert edge (RID_1 from cache, RID_2 from cache)

}

On my machine this approach resulted the application to "hang" a while after it started to create vertexes. I increased the cache size to 1M entries (I'm using Apache's LRUMap) as I had too much misses causing selecting RIDs from the DB . Strangely enough this din't have any positive impact on performance. 

Profiling the application revealed that with huge LRUMap (1M entries) it takes very long (~200ms) to get the OID from the map (not sure if this is the same with HashMap) . So I reorganized the import process to insert vertexes as soon as possible. Like this (pseudo code):

 insert vertex1 in DB

 put RID_1 in cache

 insert vertex2 in DB

 put RID_2 in cache

 insert edge (RID_1 from cache, RID2 from cache)

 insert vertex3 in DB  

 put RID3 in cache

 insert edge (RID1 from cache, RID3 from cache)

 ....

Now my cache size is only 10000 items and the whole process completes in about 40 minutes on my machine. Monitoring the cache shows I have no misses. 

To sum up, make sure the HashMap performs well with your amount of data! If not, try to reorganize the import to reduce the amount of data in the map or use different structure. 

Not sure it is even possible in your case, but I just thought I'll share my findings. 

Regards,

Milen

[Konrad]

I've been reading around the Groups (both Gremlin and Orient) and still haven't found out how to do this "disable transactions".

There is written on the OrientDB wiki that disabling transactions (along with specifying intent) will speed up bulk inserts but I haven't figured out how that is done with OrientGraph or OrientBatchGraph.

Couldn't just the use of  OrientBatchGraph both specify intent "massive insert" and disabling transactions in underlying Orient database? Or this is what's already happening?

In that case, then there should be no point in using BatchGraph wrapping a OrientBatchGraph right?

Kind regards,

Konrad

Hi,

using OrientBatchGraph class you avoid transactions and the massive insert intent is declared by default ;-)

Hi All,

Has anyone come up with a preferred solution for this?  Using tinkerpop 2.2.0 and orient 1.3 i have tried using 4 different approaches (GraphMLReader, BatchGraph<OrientGraph>, OrientBatchGraph and OGraphDatabase directly) to load a graph with about 100K vertex and 200K edges and is structured as 100 trees that go 4 levels deep.  This load is taking over a minute for all methods ranging from 62 seconds to 78 seconds.  There is not that much difference in time so I'm assuming the slow down is due to some configuration issue and not the specific api used but I'm just not seeing it.  This solution will need to scale to about 10 to 20 million vertex and 30 to 40 million edges in production and run regularly.  I have attached the 4 classes implementing the load. 

Any feed back would be greatly appreciated.

Looks like Darren didn't get a resolution for insert speeds with OrientDB.  I found this:  http://blog.euranova.eu/wp-content/uploads/2013/10/an-empirical-comparison-of-graph-databases1.pdf

I'm seeing very similar problems with 1.5 and inserting into a graph with about five vertex classes and 7 edge classes but with fairly high cardinality of edge instances to vertex instances.

What should we expect from OrientDB in terms of insertion speed?

Hi,
Any updates on this?  Been struggling with this problem also.    I test loaded an RDF/XML file with 48631 triples and the total time to complete is:

TOTALTIME (ms): 971055

And this is a load onto an empty database.  When i load a file that has nodes with less edges, timing is very fast .

        OrientGraphNoTx graph = new OrientGraphNoTx(remoteDbsUrl, remoteDbsUser, remoteDbsPwd);
        graph.getRawGraph().declareIntent(new OIntentMassiveInsert());
       
        Sail s = new GraphSail<OrientGraphNoTx>(graph);
        SailGraph sailGraph = new SailGraph(s);
