Adding this property for key [~T$SchemaName] and value [...] violates a uniqueness constraint


Matteo Lissandrini <matteo.l...@...>
 

Is this just an arbitrary design decision or is it technically impossible in this architecture?

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

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

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

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

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.

Boxuan

Can you help me?
