do you mean that you are adding properties to the schema or that you are
adding property values to existing vertexes?
What I suggest you is:
- create schema with properties before the insert operations (this will
save space on the disk because property names are not stored in the record
have any suggestion?
Thanks.

Hi Florin,
null is a valid value for a property, so setting it to null just leaves it
there, in the document.
If you want to completely remove a property you have to use this statement:
update MyClass remote myPropertyName where...

Hi Oleg,
it seems to be ok, the throughput depends a lot on the size of single
documents, on the number and type of indexes you use (I can say that Lucene
indexes demonstrated to have the best performance in insert) and on the
type of connection you are using (plocal or remote).

Hi Stas,
you could implement a hook for this. You can do this in Java or Javascript
(see http://www.orientechnologies.com/docs/last/Hook.html ), just ensure to
* bind your application logic on the following events: onBeforeCreate,
onBeforeUpdate
* let your hook functions return RECORD_CHANGED
Hi Valeri,
composed indexes in some cases can be used also in basic queries, eg. if
you have an index defined on properties A, B and C, the following will use
the index too:
select from Foo where A = 1
It is only true if the fields in the query are a prefix of the index
itself (eg. properties
