Hello,

I'm having this error thrown at me during loading of a large graph (dbpedia)

and I cannot understand what is it complaining about.

Can you help me?

Thanks,

Matteo

Hi Matteo,

The error log is indeed a bit counter-intuitive. Looks like your program was trying to create a new property (or label), but the property (or label) already existed in the database.

You may want to check your program. I would suggest checking the existence of property (label) before trying to create one.

Regards,

Boxuan

Are you running the code against a clean database? Does the property already exist before you run this piece of code?

Hi Boxuan,

thanks for the reply.

This is the full error:

org.janusgraph.core.SchemaViolationException: Adding this property for key [~T$SchemaName] and value [rtns8_designation] violates a uniqueness constraint [SystemIndex#~T$SchemaName]

I actually run a distinct before creating the schema

here is the relevant piece of code

https://pastebin.com/BaYc5ej5

So I am quite sure I am not creating it twice. Any ideas?

Thanks,

Matteo

Yeah, that's possible. You need to make sure properties and labels don't have the same name.

I am loading a graph from scratch in an empty database.

Could it be that there may be an edge label and a property name with the same name?

Correct. See https://docs.janusgraph.org/basics/schema/#relation-types
