Hi Diaa,
if you are implementing your functions in Javascript you can refer to this
http://orientdb.com/docs/last/Functions.html
To implement functions in Java, instead, you have to implement OSQLFunction
interface and register functions in the database using
the less, it should be possible to do such transactions also on
remote. So that it is possible for multiple worker to upload data to the
database.
Any ideas how to make this faster?

let $comments = sort(out('PostHasComment'))

Hi Simon,
my mistake, I was not clear at all, the sort() function is not a built-in
function, my proposal was to implement your own function called sort() in
javascript and use it in the query

Hi Stefan,
try to remove parentheses from your query, like this:
insert into GermanyClient from select from Client where country = 'Germany'
current SQL parser implementation sometimes is not so friendly, we are
completely rewriting it and the new one will be released in 2.1

Hi Riccardo,
what TinkerPop calls labels is represented by OrientDB classes.
You can create a lightweight edge of a particular class with this syntax:
CREATE EDGE MyLabel FROM #14:1 TO #14:0
Of course the class MyLabel has to exist and has to extend E
If you use the SET labelName = value, the

Hi Jan,
in this use case you will not have big advantage from typical NoSQL
features like index free adjacency (that means fast traversal) or dynamic
schema management. You are actually using OrientDB as a relational db.
Anyway performance you are having is definitely too slow!
I suggest you to
ah, for cases where you know that you don't need range queries I suggest
you to use OClass.INDEX_TYPE.NOTUNIQUE_HASH_INDEX, it's much much faster!

Hi Charles,
at this moment there is no built-in procedure to encrypt root password,
anyway IMHO this problem can be bypassed with some simple modifications.
The real problem is another one: the DB files are not encrypted in any way,
so if your customer copies the orient/databases/ directory on
Hi,
the best thing to do this should be something like this:
update myClass set columnB = columnA.split(,)
but unfortunately it's NOT supported at this time.
As a work around, you can define your own split() function like this
- two parameters: inputString and separator
- this function body:
Hi Mark,
one or two years ago I tested OrientDB on Raspberry PI and it worked fine
(of course the performance was not the same as on my laptop, but it was
more than acceptable). At that time I used Java8 alpha for ARM and that
gave me very good results.

Of course you can use this approach, this is not bad practice in general,
but sometimes you can find easier solutions to do that.
Here are a couple of examples, they all work fine for me.

Am I missing something in the release 2 M2 version ?
Also, are you planning to have a backup to file system ( not snapshot) and

Hi Frederik,
this kind of issues is related to some legacy code in current query parser
implementation. We are completely rewriting it, so it will be fixed in 2.1.
If you want you can open an issue about this, I'll take care of it.
About third query, I tried it in Studio with a fresh
