MariaDB HA: Pieces of the Puzzle

● GTID: Global Transaction ID

● Domain ID - Server ID - Transaction seq #

● Multi-source replication

● Optional:

● Virtual IP

● Semi-sync replication

● Parallel replication / group commit

● MaxScale

● MariaDB Java connector

MariaDB HA: System Variables

● GTID are always on in MariaDB 10.0

● Default domain id = 0

● Default server id = 0

● Set domain ID according to application semantics

● Global variable: SET GLOBAL gtid_domain_id = 1;

● Config file: gtid-domain-id=1

● It can be specified by session

● Domain ID = Write Domain

● Server ID is the same as regular MySQL / MariaDB

● Dynamic global and session variable 10

MariaDB HA: Multi Source

● Ignore transactions with same GTID

● Global variable: SET GLOBAL gtid_ignore_duplicates = ON;

● Config file: gtid-ignore-duplicates = 1

● Create new replication streamCHANGE MASTER 's-102' TO MASTER_HOST='192.168.56.102', MASTER_USER='repl', MASTER_PASSWORD='repl', master_use_gtid=slave_pos;

START SLAVE 's-102';
