Comments - Unknown option 'data_table' OQGraph in MariaDB 10.0.7

You have a typo. it is data_table not table_data.

CREATE TABLE oq_graph (
  latch VARCHAR(32) NULL,
  origid BIGINT UNSIGNED NULL,
  destid BIGINT UNSIGNED NULL,
  weight DOUBLE NULL,
  seq BIGINT UNSIGNED NULL,
  linkid BIGINT UNSIGNED NULL,
  KEY (latch, origid, destid) USING HASH,
  KEY (latch, destid, origid) USING HASH
) 
ENGINE=OQGRAPH 
data_table='oq_backing' origid='origid' destid='destid';

You're right, my typo was in my question not my actual query. I have fixed it in my question. The text that I used to create the table was a copy/paste. Sorry for the typo.
