High Availability

• Principles of High Availability Elimination of single points of failure Reliable crossover. In multi threaded systems, the crossover point itself tends to become a single point

of failure Detection of failures as they occur. If the two principles above are observed, then a user may never

see a failure. But the maintenance activity must

MySQL Group Replication

• What is MySQL Group Replication ?Update everywhere replication plugin for MySQL with built-in automatic distributed recovery, conflict handling, group membership and distributed agreement.

• What does the MySQL Group Replication plugin do for the user Removes the need for handling server fail-over. Provides fault tolerance. Enables update everywhere setups. Automates group reconfiguration (handling of crashes, failures, re-connects). Provides a highly available replicated database. Automatic distributed coordination (protects against split-brain and message loss). The number of servers (n) needed to tolerate f failures is based on formula n = 2 x f + 1.

MySQL Group Replication Requirements

• Infrastructure Data must be stored in the transactional storage engine InnoDB Every table must have a primary key IPv4 network Low latency, high bandwidth network Up to 9 servers in the group

• Configuration Binary Log must be active Binary Log Format must be set to ROW Global Transaction Identifiers must be turned on Replication applier needs to have replication metadata repositories stored in system tables Transaction write set extraction must be enabled Servers need to log binary logs that are applied through the replication applier

Plugin Architecture

• Built on top of proven technology! Shares much of MySQL Replication infrastructure thence does not feel alien!Multi-Master approach to replication.

• Built on reusable components! Layered implementation approach. Interface driven development. Decoupled from the server core. The plugin registers as listener to server events. Reuses the capture procedure from regular replication. Provides further decoupling from the communication infrastructure.
