Add Optional Invisible Primary Key to History for Replication in MySQL and MariaDB

[sm-shaw]

Pull Request adds an optional primary key for the history table which is needed for replication.

option mysql/maria_history_pk is added to the config/CLI.

<schema>
            <mysql_count_ware>1</mysql_count_ware>
            <mysql_num_vu>1</mysql_num_vu>
            <mysql_user>root</mysql_user>
            <mysql_pass>mysql</mysql_pass>
            <mysql_dbase>tpcc</mysql_dbase>
<mysql_storage_engine>innodb</mysql_storage_engine>
            <mysql_partition>false</mysql_partition>
            <mysql_prepared>false</mysql_prepared>
            <mysql_history_pk>false</mysql_history_pk>
        </schema>

Change will check that the InnoDB storage engine is being used and that the MySQL/MariaDB version is at a level that supports inivisible primary keys before adding one. If not it falls back to the default option.

Example change in table with and without.

mysql> show create table history\G
*************************** 1. row ***************************
       Table: history
Create Table: CREATE TABLE `history` (
  `h_c_id` int DEFAULT NULL,
  `h_c_d_id` int DEFAULT NULL,
  `h_c_w_id` int DEFAULT NULL,
  `h_d_id` int DEFAULT NULL,
  `h_w_id` int DEFAULT NULL,
  `h_date` datetime DEFAULT NULL,
  `h_amount` decimal(6,2) DEFAULT NULL,
  `h_data` varchar(24) CHARACTER SET latin1 COLLATE latin1_bin DEFAULT NULL,
  `id` int NOT NULL AUTO_INCREMENT /*!80023 INVISIBLE */,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=30001 DEFAULT CHARSET=latin1
1 row in set (0.00 sec)
*************************** 1. row ***************************
       Table: history
Create Table: CREATE TABLE `history` (
  `h_c_id` int DEFAULT NULL,
  `h_c_d_id` int DEFAULT NULL,
  `h_c_w_id` int DEFAULT NULL,
  `h_d_id` int DEFAULT NULL,
  `h_w_id` int DEFAULT NULL,
  `h_date` datetime DEFAULT NULL,
  `h_amount` decimal(6,2) DEFAULT NULL,
  `h_data` varchar(24) CHARACTER SET latin1 COLLATE latin1_bin DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1
1 row in set (0.00 sec)

When testing on an incompatible version

mysql> select @@version;
+-----------+
| @@version |
+-----------+
| 8.0.20    |
+-----------+
1 row in set (0.00 sec)

Message is reported the minimum supported version but continues anyway without the invisible PK.

This way it should allow adding the primary key for replication where it is needed, but also provide minimal disruption where it is not.

Same change in MySQL and MariaDB
