[#5761] - Datasource schema is limited to 1000 characters

When adding a schema to a MongoDB Datasource (so i can use it with a Virtual Datasource) it gives me the following message :

Failed to save data source.
The reason is: Could not execute JDBC batch update: ERROR: value too long for type character varying(1000)

The full response from the server is: {"message":"Could not execute JDBC batch update: ERROR: value too long for type character varying(1000)","errorCode":"illegal.parameter.value.error"}

My schema will contain more then 1000 chars, can this limit be removed?
When i limit my schema it can be saved, but the schema is incomplete (and therefore not useable)
