how make schema less titan graph?how set schema-default propery ? please suggest way?here code :

how set scheme-default configuration? how set default automatic schemas generated?please suggest way or alternative ?

titan set in configuration default. elaborate, settings schema.default set blueprints automatically. force schema definition, need set value none. docs read:

configures defaultschemamaker used graph. if set none, automatic schema creation disabled. defaults blueprints compatible schema maker multi edge labels , single property keys

to enforce schema need this:

conf.setproperty("schema.default","none"); 

and use "default" schema creation system should do:

conf.setproperty("schema.default","blueprints"); 

all said, bad idea allow titan create schema except simple cases. if don't provide titan schema, lose many optimizations , features titan provides , therefore performance may not possible be.
