i want to drop class named "zzz"

can work:

        ODatabaseSession session = pool.acquire();
        OResultSet rs = session.command("drop class zzz");
        rs.close();

not work:

        ODatabaseSession session = pool.acquire();
        OResultSet rs = session.command("drop class ?" ,"zzz");
        rs.close();

is it unsupported ?

got it ,thank you.

Oh yes, sorry, I got it... The problem is the parameter. No, it's not supported for DROP CLASS in the new SQL executor, but I can implement it right away, it's pretty easy. It will be in v 3.2.1

Thanks

@luigidellaquila

wait please... db.command(String query, Object... args) throw the exception too.

Hi @tonglsh

db.query() is only for queries that do not modify the state (ie. SELECT, TRAVERSE, MATCH...). For DROP you have to use db.command()

Thanks

Expected behavior

Am pushing batch of vertex through REST API from java via Thread.It results in Socket java.net.SocketTimeoutException: Read timed out .Am i missing any configuration here ?I've tried configuring NETWORK_SOCKET_TIMEOUT,still same exists.Kindly help me on this.

It all depends on how big is each vertex. How many properties? Do you have binary or long strings? If you can compute that amount in terms of total Kb sent it would be helpful.

Generally speaking, if you're sending big packets concurrently, OrientDB's web socket could having hard time to process the requests.

Try reducing the parallel threads from 10 to 3 and see how it goes. Also from 1000 vertices, try with 300.

Try to play around those numbers to see a good configuration based on your data and hw/sw available.

I am inserting 1000 vertices as JSON through rest API from java.

The size of the packet is 1000 and parallely running 10 threads.

3.1.7 also works. I cant go beyond this.
