Hi,
Any changes to the database, as adding Vertex/Edge types, needs to be done
outside the transaction.
I'm inserting new records in a batch and to solve this, in that situation,
I pre-iterate through the batch to check for new types, create them and
then start a transaction to insert.
Does that clarify anything?
Regards,
-Stefán
