      Description

      According to MySQL manual (http://dev.mysql.com/doc/refman/5.5/en/replication-options-master.html#sysvar_auto_increment_increment), if the combination of values is valid, the auto-increment sequence should start from auto_increment_offset. With TokuDB, it starts from auto_increment_offset+auto_increment_increment – in other words, the first value is omitted.

      SET auto_increment_offset = 200;
      SET auto_increment_increment = 300;
      CREATE TABLE t1 (a int AUTO_INCREMENT, b char(8), primary key(a)) ENGINE=TokuDB;
      INSERT INTO t1 VALUES (NULL,'a'),(NULL,'b'),(NULL,'c');
      SELECT LAST_INSERT_ID();
      LAST_INSERT_ID()
      500
      SELECT a,b FROM t1;
      a	b
      500	a
      800	b
      1100	c

      Test case:

      install soname 'ha_tokudb.so';
       
      SET auto_increment_offset = 200;
      SET auto_increment_increment = 300;
      CREATE TABLE t1 (a int AUTO_INCREMENT, b char(8), primary key(a)) ENGINE=TokuDB;
      INSERT INTO t1 VALUES (NULL,'a'),(NULL,'b'),(NULL,'c');
      SELECT LAST_INSERT_ID();
      SELECT a,b FROM t1;
