Re: [orientdb] no backwards compatibility
Hi Jamie, As any database they change their disk based data structures to provide additional performance improvements. But providing support for old binary formats is good thing. I think we implement it. About first two points you can read answer here https://groups.google.com/forum/#!topic/orient-database/Ln9RfUu6pY8 Could you follow mentioned before thread, it will be easier to track all conversion in single place. On Wed, Dec 18, 2013 at 9:40 AM, Jamie ja...@mailarchiva.com wrote: Andrey I just run apt-get update. to update Mysql. The point is the database upgrades seamlessly. We do not have to do anything. Granted I have not tried running Mysql in embedded mode so I cannot comment on whether replacing the binary works or not... my guess is it will. However, when running Orient in embedded mode, there should be a way to: 1) Detect the specific version of database that is being used (so that you can identify whether it is necessary to upgrade the database) 2) Provide an API to convert the database to the new format (whether this involves exporting the database to a file or by whatever mechanism, there need to be an upgrade path) 3) Ideally ability to read the old database format (so that you can benefit from bug fixes in the new code base) Also, surely point releases e.g. v1.5-1.6, should imply no change to the underlying binary format of the database. Surely, your users cannot be expected to make massive changes to their database every time you come out with a point release.

Re: [orientdb] Titan-Cassandra Combination vs OrientDB
translate into vertices per se). 2. A federated model/system is acceptable 3. Over and above the 500-750 billion live sample, the application will have a couple of million records (just in case an additional drop created chaos in the ocean :) ) Given that we can store JSON data in Cassandra (with the knowledge that marshalling and umarshalling will induce latency) and Titan can provide graph relationship, what, in the estimation of this community tips the scales in favor of OrientDB. At the time of this writing, I have only managed to scratch the surface and I am relatively new to NoSQL and Big Data systems in general. So, if the question lacks clarity/depth, please let me know and I will share any additional information required Thanks LSP PS - Wishing you all a happy new year and a great 2014. -- --- You received this message because you are subscribed to the Google Groups OrientDB group.

Re: [orientdb] Newbie OrientDB REST graph edition question.
Hi,
You can use following approach
https://github.com/orientechnologies/orientdb/wiki/Gremlin#passing-input-parametersso
just wrap your select query in gremlin operator:select
gremlin('query is here
')

I am very new to orientdb but the technology looks very interesting. I
downloaded version 1.6.3 of the community edition, and using a REST client
I am able to perform SQL queries.
http://localhost:2480/query/GratefulDeadConcerts/sql/select%20*%20from%20V
I would like to also be able to use gremlin queries, but the syntax does
not seem to be recognized and the error message I get includes a mention of
sql which makes me think perhaps I am running the wrong edition,
http://localhost:2480/query/GratefulDeadConcerts/gremlin/g = new foo()

responseText:
com.orientechnologies.orient.core.command.OCommandExecutorNotFoundException:
Cannot find a command executor for the command request: sql.g = new foo(),
status: 500,
statusText: Internal Server Error
}
Can anyone give me an example REST query against the grateful dead
database which should work.
Also is there a difference between orientdb standard and the graph
edition, if so how can I make server.sh launch the graph edition instead of
the document edition.
It seems like the graph edition is an extension of the document edition
which can do more, are there reasons why I should not always use it, does
it have performance implications.
Sorry if these questions are already answered in the documentation, if so
please point me to it.
Thanks in advance

Re: [orientdb] how many graphs
Hi Alan, You can create as many graphs as you need in single Graph instance. It is better than create 3000 graph databases because in case of single storage you will have much efficient RAM usage than in case of 3000 storages. You can tune RAM consumed by memory storage using storage.diskCache.bufferSize it is in megabytes. About your question, there is no limitation on amount of db instances on server. but much better to create several graph instances on single db and use name pattern for partitioning of graph data. For example class_one_partition_one, class_one_partition_two and so on.

you want pre-fill import data you can use noTx version of graphdb.
Halo,
Is this of interest?
Is commiting every 10 to coarse?
Thanks

After inserting the 4 900 000 record I am getting a OutOfMemoryError

I first ran it with no settings but even with -Xms1024m -Xmx6144m it still
gets OutOfMemoryError.
Does this point to a memory leak somewhere?

Hi, You can use detach/attach functionality. Call com.orientechnologies.orient.object.db.OObjectDatabaseTx#detach method and you will not have to copy data so you can use it as web layer DTO. Also you do not need to load entity to save it, just save it without load, you asked how to load entity that is why I mentioned load method.

Re: [orientdb] Maximum lock count exceeded and OutOfMemoryError
Hi Jun, Both of issues which you described are fixed in https://github.com/orientechnologies/orientdb/tree/rid-set-sbtree branch (we do not support remote storage yet) but as I can see you use embedded storage any way. Could you use plocal storage for your tests. About memory consumption OrientDB uses heap and direct memory (it consumes 4GB by default) if you would like to decrease amount of consumed memory you can set storage.diskCache.bufferSize property (in megabytes). Also about blueprints-orient-graph-2.5.0-SNAPSHOT dependency, it is not needed any more, blueprints implementation is embedded in graphdb so please drop this dependency. P.S. And finally about comparison to Neo4J insertion speed we have proposal for append only cluster which should improve insertion speed. P.S.2 looking forward for your feedback ! On Fri, Jan 17, 2014 at 10:56 PM, Jun Xu mail.ju...@gmail.com wrote: Hi, I'm evaluating different graph database products and am new to OrientDB. One use case I'm testing now is loading data to graph database. The use case basically is building a graph with half million vertices and a few millions of edges. I'm using OrientDB 1.6.4 on a CentOS Linux box with 8GB of memory and the CentOS version is 5.10 and the JDK is 1.7.0_40. The blueprints version is blueprints-core-2.5.0-SNAPSHOT and blueprints-orient-graph-2.5.0-SNAPSHOT. I use OrientGraph to build the graph. During initialization, it creates an OrientGraph instance (plocal or local storage engine) and creates a few key indices using createKeyIndex on vertex nodes. The building process does index based lookups (OrientGraph.getVertices()) on vertices and based whether the vertices exist or not, it will create them and set properties, or create edges and set properties on edges. There are no global index based lookups on edges. Edges are always reached via vertices. I load the data in batches (each batch probably has a few hundreds operations like looking up a vertex, creating a vertex, getting all edges of a vertex, creating an edge and setting a property etc.) and commit transaction at the end of each batch. After processing around 300 batches, an exception of Maximum lock count exceeded was thrown. I tried both local and plocal storage engine and got the same exception. I searched this group and got to know that OrientDB used to have this bug in very old versions and I'm using the latest version (1.6.4). Since the exception was thrown in transaction commit, I changed to use the OrientGraphNoTx interface. Without transaction enabled, I did not get the Maximum lock count exceeded exception but I noticed that the process was really eager for memory. Giving JVM 4GB of max memory, the speed was OK although still slower than Neo4j for the same process. I did not let the process finish once I saw the memory usage growing to 3GB. I restarted the process by giving JVM only 1GB of maximum memory and after running the process for 2 and half hours, an OutOfMemoryError was thrown. While with Neo4j, the whole loading process was finished using 1GB of maximum memory with quite good performance. Another thing I noticed was that the database size on disk is much bigger than the database size using Neo4j. At half way of the loading process, the OrientDB DB directory is already at 4GB, while for Neo4j the DB directory size is only 1.6GB after the whole loading process is finished. I actually really like the way OrientDB is designed, the mix of document and graph features and the binary protocol on remote interfaces. I really appreciate if you can help me get around the hurdles mentioned above. I might have done something wrong or maybe there are some tuning can be done. Thanks.

Re: [orientdb] Maximum lock count exceeded and OutOfMemoryError
Hi Stefan, The append only cluster roughly speaking means that all changes are append only deletes/updates and additions of course are append only. But cluster consist of logical segments and those segments they are defragmented in background and their space is reused. So lets suppose we have cluster file with lets say 3 segments each 150MB (actually a lot of data). then we have situation like: 1-st segment is empty. 2-nd segment is empty. We do creations, updates deletes and so on. so we have: 1-st segment is full 2-nd segment is half empty In background we do 1-st segment defragmentation. we load 1-st segment in memory then extract only useful data (drop all out of dated after updates and deletes) and put in 2-nd segment. So as result we have: 1-st segment is empty 2-nd segment is full and we start to work(add data to) with 1-st segment once again. So virtually you always append data. It gives following advantages: 1. you work without random i/o (only small fraction of operations will be suffer from random io). 2. More scalable from mulitthreading point of view , you append only data so reads do not compete with writes. From user perspective all operations are supported.

Re: [orientdb] Oversize and edges
Stefan, We are going to release first version of implementation of new relations in graphdb which is sometimes 20x (that is true) times faster than current one. Aslo data structure is used in this relations was tested by Kai Londenberg and he confirmed https://groups.google.com/forum/#!searchin/orient-database/sbtreebansai/orient-database/ltNElAF0H_o/uQOwqAliUH8Jthat even on millions of relations there is no performance degradation. I attached also early benchmarks, that is benchmark of import or Wikipedia data in OrientDB. Firs line amount of records, second line time spent for insertion of 100 000 records. Full benchmark which we will run during 12 hours will be published at Monday (ridbag is new impl ridset is old impl). About your question in case of more than 50 links (roughly speaking) these links are stored in separate data structure so you should not worry about oversize.

Re: [orientdb] OObjectDatabaseTx get
Hi Francis,
When open database (acquire from pool) property
ODatabaseRecordThreadLocal.INSTANCE
is automatically set.
Acquiring connection from poo is cheap operation, so you can do something
like:
OObjectDatabaseTx db = OObjectDatabasePool.global().acquire(dbURL,dbUser,
dbPwd);
try {
} finally {
db.close();
}
In your methods without performance loss.

Hello I am trying to use OObjectDatabaseTx with a webapp, i thought i
might follow the example in the documentation but just use the

so something like:
OObjectDatabaseTx db = OObjectDatabasePool.global().acquire(dbURL,dbUser,
dbPwd);
ODatabaseRecordThreadLocal.INSTANCE.set(db.getUnderlying());
it seems I can't put the OObjectDatabaseTx db object in the ThreadLocal so
i have to use the getUnderlying() method,
where I am stuck is creating myself an OObjectDatabaseTx outside of my
servlet filter:
ODatabaseDocument localdbthread = (ODatabaseDocument)
ODatabaseRecordThreadLocal.INSTANCE.get();
i assume i need to do something more to turn localdbthread back into a
OObjectDatabaseTx or create an instance of OObjectDatabaseTx using
ODatabaseDocument?
Thanks in advance

Re: [orientdb] Re: OrientDB 1.7 - OGraphDatabase will be removed. What ?!?!
Hi,
To create graph db in such way just use
db = Orient.instance().getDatabaseFactory().createDatabase(graph, plocal:
+ dbPath)
if (!db.exists()) {
info(DB does not exist, BaasBox will create a new one);
db.create();
}
About the second question, you have several variants.
Two of them:
1. db.addVertex(class: + CLASS_VERTEX_NAME);
2. db.addVertex(CLASS_VERTEX_NAME, null);

Your mistake is that you store vertex in separate cluster not associated with given class (it has the same name as class) but you did not add cluster id in list of clusters for given class. So queries do not take this cluster in account. So if you need to have 2 clusters for given class call following method com.orientechnologies.orient.core.metadata.schema.OClass#addClusterId. But probably, as I understand from your design, you need each class in separate cluster which is already done and you should not need to do any additional steps.

Couple of words about benchmark.
We imported wikipedia data using OrientGraph database, to be sure that we
have no duplications unique index by page key was created.
First benchmark that is benchmark which uses 1.6.4 version of OrientDB and

Re: [orientdb] OrientDB and nameUUID (Version 3 UUIDs)
You can use manual indexes. Also you can create feature request the more users will vote for it the more chances that it will be implemented earlier.

Let me encourage you though to add UUID field type support to some nice road-map somewhere :) The best thing for me though would be to have the transient field that does not get stored at all (only indexed) :).

That means that their ID can even be calculated on the client before they are persisted. - A unique signature is processed with: java.util.UUID nameUUIDFromBytes(signature) A typical ID looks like this 172ecd63-9c62-380d-a0a1-c45ca8883bc7 (more information here http://en.wikipedia.org/wiki/UUID#Definition) and currently I'm forced to store it as a String. Either of two things would make my life considerably easier: - Support for efficient storage of UUIDs in OrientDB making UUIDs first class citizens - Support for transient properties that are only indexed but not stored I know I can implement the latter with an index that I maintain myself but I will only do that as a last resort.

Re: [orientdb] Creating memory cluster in a physical database (OrientDB 1.6.4)
Hi Peter, This functionality is disabled till we will implement dmemroy storage - https://github.com/orientechnologies/orientdb/issues/1666 .

Re: [orientdb] Re: Error of loading big graphml to database
Hi Nikita, 1. Do not use local storage it is out of dated, use plocal. 2. We will release this week (just wait 2 days) first rc of new graph relations implementation it is about 7 times faster on big data. In attachment there is benchmark of import of 130 mln of nodes and about 1.5 billion of edges. Also if you do benchmark to test speed of import data it is applicable to use notx mode but if you do benchmark of insertion speed in production I recommend you to use OrientGraph version of database so you will avoid data inconsistencies in case of concurrent modification exception .

Re: [orientdb] Database 'plocal:/graphdb_tests_orient' is close
Andrey,
I looked through you code, you did not do graph.shutdown() before db drop
so internal graph context is not cleared and graph db tries to check that
schema is needed for graph database is present without db open.
So just do graph.shutdown() but I do suggest you to wait till tomorrow, we
release new version of graph db relation management tool with much better
performance.

Hi there,
I'm back with a bunch of questions again.
Today I faced a strange issue.
I'm running tests, trying to figure out pros and cons of OrientDB. Each
test I run in a new DB, so I'm creating and dropping DBs with the same name.
Here is how I'm doing this
Create DB
public static void createDB()
throws IOException {
if (dbUrl.startsWith(remote)) {
OServerAdmin server = new OServerAdmin(dbUrl).connect(dbUser, dbPassword);
if (!server.existsDatabase(plocal)) {
server.createDatabase(graph, plocal);
}
server.close();
}
else {
//OGraphDatabase database = new OGraphDatabase(dbUrl);
OrientGraph database = new OrientGraph(dbUrl);
if (!database.getRawGraph().exists()) {
database.getRawGraph().create();
}
database.getRawGraph().close();
}
}
Drop DB
public static void dropDB()
throws IOException {
if (dbUrl.startsWith(remote)) {
OServerAdmin server = new OServerAdmin(dbUrl).connect(dbUser, dbPassword);
if (server.existsDatabase(plocal)) {
server.dropDatabase(plocal);
}
server.close();
}
else {
OrientGraph database =
new OrientGraph(dbUrl);
if (database.getRawGraph().exists()) {
if (database.isClosed()) {
database.getRawGraph().open(dbUser, dbPassword);
}
OIndexManager indexManager =
database.getRawGraph().getMetadata().getIndexManager();
for (@SuppressWarnings(rawtypes) OIndex index :
indexManager.getIndexes()) {
index.delete();
}
database.drop();
}
database.getRawGraph().close();
}
}
Get DB
public static synchronized OrientGraph getDatabase() {
return new
OrientGraph(OGraphDatabasePool.global().acquire(dbUrl,
dbUser, dbPassword));
}
I'm actually using project from this thread
https://groups.google.com/forum/#!searchin/orient-database/bemchmark/orient-database/VF_j5rGeffA/hzyC9PVj9lAJ
.
Have to say thanks to Milen Dyankov for a great job he did there.
I changed it a little bit though...
So, here is the problem I faced.
I'm using OrientDB 1.6.4, remote connection.
1. Create DB
2. Do my tests. 4 threads simultaneously writing to DB
3. Drop DB
4. Create DB
5. Get an exception trying to create a vertex
OrientVertex vertex = db.addVertex(OGraphVertex, null);

Thx for the respoce.
3) yes, we support such range queries
just to have no doubt:
- OrientDB uses indexes to report them, yes ?
- it does not have to iterate over the all documents, the index already
idicates which ones have obj.number 8 ?
- it doesn't have to do any not index wise sorting algorithm, it can give
back an ordered set just by navigating the index ?
4) there is but it's poor supported: Native Query. Example:
ONativeSynchQueryOQueryContextNative q =
(ONativeSynchQueryOQueryContextNative)
new
ONativeSynchQueryOQueryContextNative(
database, Profile, new OQueryContextNative()) {
@Override
public boolean filter(OQueryContextNative iRecord) {
return iRecord.field(location).field(city).field(name).
eq(Rome).and().field(name).like(G%).go();
}
@Override
public void end() {
};
}.setLimit(20);
ListODocument result = (ListODocument) q.execute();
But is this really a query. When using the above code does OrientDB use
the index to find the location with the given city name ?
Or does it iterate over ALL locations and perform comparisons on each one
?

Re: [orientdb] Difference between embedded configuration and orientdb-server-config.xml?
Hi, Embedded server and server which you run by server.sh are exactly the same the difference only that you can access database like it was embedded without remote connection overhead. So content of server-config.xml or configuration provided inline is defined by your needs, if you do not need remote protocol or http just remove it the same about mail plugin and so on., On Tue, Feb 4, 2014 at 8:12 PM, Tommy itsdu...@gmail.com wrote: Hello, I was wondering if there was difference between the embedded configuration from the Embedded Serverhttps://github.com/orientechnologies/orientdb/wiki/Embedded-Server#wiki-use-an-embedded-configuration wiki and orientdb-server-config.xml.

I looked through you code, you did not do graph.shutdown() before db drop

Hi there,
I'm back with a bunch of questions again.
Today I faced a strange issue.
I'm running tests, trying to figure out pros and cons of OrientDB. Each
test I run in a new DB, so I'm creating and dropping DBs with the same
name.
Here is how I'm doing this
Create DB
public static void createDB()
throws IOException {
if (dbUrl.startsWith(remote)) {
OServerAdmin server = new OServerAdmin(dbUrl).connect(dbUser,
dbPassword);
if (!server.existsDatabase(plocal)) {
server.createDatabase(graph, plocal);
}
server.close();
}
else {
//OGraphDatabase database = new OGraphDatabase(dbUrl);
OrientGraph database = new OrientGraph(dbUrl);
if (!database.getRawGraph().exists()) {
database.getRawGraph().create();
}
database.getRawGraph().close();
}
}
Drop DB
public static void dropDB()
throws IOException {
if (dbUrl.startsWith(remote)) {
OServerAdmin server = new OServerAdmin(dbUrl).connect(dbUser,
dbPassword);
if (server.existsDatabase(plocal)) {
server.dropDatabase(plocal);
}
server.close();
}
else {
OrientGraph database =
new OrientGraph(dbUrl);
if (database.getRawGraph().exists()) {
if (database.isClosed()) {
database.getRawGraph().open(dbUser, dbPassword);
}
OIndexManager indexManager = database.getRawGraph().
getMetadata().getIndexManager();
for (@SuppressWarnings(rawtypes) OIndex index :
indexManager.getIndexes()) {
index.delete();
}
database.drop();
}
database.getRawGraph().close();
}
}
Get DB
public static synchronized OrientGraph getDatabase() {
return new
OrientGraph(OGraphDatabasePool.global().acquire(dbUrl,
dbUser, dbPassword));
}
I'm actually using project from this thread https://groups.google.
com/forum/#!searchin/orient-database/bemchmark/orient-
database/VF_j5rGeffA/hzyC9PVj9lAJ . Have to say thanks to Milen Dyankov for
a great job he did there.
I changed it a little bit though...
So, here is the problem I faced.
I'm using OrientDB 1.6.4, remote connection.
1. Create DB
2. Do my tests. 4 threads simultaneously writing to DB
3. Drop DB
4. Create DB
5. Get an exception trying to create a vertex

You mix group and row level functions I mean that list() is group function

should use let.

Re: [orientdb] Minimum recommended hardware specs
Hi Greg, Some components will utilize mutlicore architecture but some will not, we are working on it but if several replicated small nodes fits into you model better use such feature.

About the rest of your questions, SQL query is typically faster than Gremlin so if you wish to increase your performance you should use document database and/or SQL queries.

Re: [orientdb] Important issue: WAL page is broken

Re: [orientdb] Re: New graph database implementation and several release candidates.
Hi Pawel, I have merged it in develop branch couple of hours ago. About your questions. 1.

The main parameter of plocal is amount of RAM for disk cache, so as you could see db is used 24 GB of RAM so you should set storage.diskCache.bufferSize parameter in megabytes.

Re: [orientdb] Re: Unintended clearing of links from vertex when modifying properties via tinkerpop framed object

Dexter On Sunday, January 19, 2014 11:19:39 AM UTC-8, Dexter Pratt wrote: Hi all, we've been working with OrientDB for several months on the NDEx project (www.ndexbio.org) , but this is my first post. We are currently running in 1.6.1. Most of our interface to OrientDB is via a Frames data model. I've encountered a problem that is proving difficult to debug because it seems to be (1) dependent on the mode of creation and population of the stored objects and (2) the problem disappears if I breakpoint my code and inspect the objects prior to commit. So, rather than starting by asking the for help and providing lots of detail on the code, I'm going to outline the problem and ask for advice on how to pin this problem down, how to generate a better bug to diagnose. The essence of the problem: - INetwork is class of object that is managed by a tinkerpop VertexFrame with both properties and adjacencies. - For one group of INetwork objects, when we perform an update on an INetwork to set one or more properties, the adjacencies are reset - all links are lost. - BUT, this does NOT happen for another group of INetwork objects. The properties are changed correctly and the links are not affected. - The most obvious difference between the two groups is that they were created using different code. The group affected by the bug was created under an OrientGraphNoTx connection as part of a massive upload strategy. The group not affected was created in standard transaction mode. - There is no obvious difference in the links when inspected in the console and both groups of graphs operate correctly in our application, all queries apparently operating without any difference (at least not that we have detected) - FURTHER, if the update operation is breakpointed in Eclipse and the INetwork object is inspected in the debugger, and then the code is resumed, then the update operation behaves correctly and the links are not affected. My current theory is therefore that there is something different between the two groups of stored INetworks that affects how the record is loaded by the VertexFrame. I might guess that the difference stems from the use of OrientGraphNoTx to load the vulnerable group, but I have no proof of that. And finally, it seems that the act of debug inspection causes alteration in the state of the VertexFrame such that the bug is averted. Thanks for any insights!

To achieve good performance, durability and thread safety we use pretty
sophisticated algorithm which allows do not fetch lets say all 700 000
links to edges during link manipulation to the client and still supports
mvcc without flaws.
So to make it simple you can use only embedded version of linkbag, for

using base 64 then you will have following binary format:
amount of items(int),first cluster id(short), first cluster position

Re: [orientdb] Binary protocol - help needed
Hi Pawel,
I do not think that providing such level of compatibility is good idea, too
much sources should be spent on this.
Probably in such case users can work in embedded mode.
You see embedded collections they of course will not allow to work with
thousands of links but support of sbtree is really resourceful change.
Lets say we never fetch them on the client if you add link to linkbag you
only register event about addition/removal of item in document and do real
operations on sever side.
Also when you iterate items in collection you do it page by page and do not
fetch all of them at once.
We will provide this format bur probably better to use embedded version
from begging.

Thanks Andrey for info.
Well, I wanted to fix my binary driver to recent version. I am during deep
dive into ORidBag,OSBTreeRidBag,OEmbeddedRidBag anyway ;)
I am wondering if it means for driver developers the need of
implementation Bonsai structures in their languages just to be able to
serialize/deserialize edges collections. If so, the entry point to write
really compatible driver will be much higher ;)
Probably also many other drivers will be not compatible. Therefore I
thought if it's possible to have two options in binary protocol (still old
simple comma separated collection which internally on server side is
serialized/deserialized to new RidBag structures or new Base64 RidBag
structures passed to binary clients.
Potentially it could be based on the protocol version. Just the idea.
Best regards,
Pawel

Hi Pawel,
What do you mean you want to retrieve document partially ?
It is internal presentation of document so it can not be turned off, we
can provide description of this format.

Re: [orientdb] Can transient field be indexed?
Hi Stefan, LINKBAG is internal type and is not supposed to be used as public API, it is used to manage graphdb relations and we can change it at any time to improve functionality of graph database. You can not index Transient type because you can not serialize it in index as a key using binary presentation, but you can use manual indexes to achieve the same functionality.

Re: [orientdb] SQL
Hi Frederik, So you mean something like create edge select from a to b match by likes ? About your second note Also, you state calling it SQL, but the first thing anyone (or am I alone?) would do in a query is returning data from different objects next to each other, so you can quickly see what you are interested in from your database, like Peoples names and the companies they work for, for example. I am not RDBMS SQL expert,could you provide example, what do you mean ? And about your question. We are thinking about reconsidering sql engine and will add new functionality to it but will not change current SQL language for something else in short future.
