Can not save new record with the sample code...

[frank-dkvan]

Below is the sample code to create a new document. after the code execution, But I can not find the record in database thru SQL like "select from Customer"

try( Database db = databaseFactory.open(); ){
  db.transaction( () -> {
    // CREATE A CUSTOMER INSTANCE
    MutableDocument customer = db.newDocument("Customer");
    customer.set("name", "Jay");
    customer.set("surname", "Miner");
  });
}

I found I have to add one more code "customer.save()" if I want to find the record in database.

try( Database db = databaseFactory.open(); ){
  db.transaction( () -> {
    // CREATE A CUSTOMER INSTANCE
    MutableDocument customer = db.newDocument("Customer");
    customer.set("name", "Jay");
    customer.set("surname", "Miner");
    customer.save();
  });
}

Correct, until you hit the .save() method the record is not persistent.
