Percona XtraDB Cluster

• What is: • Is MySQL binary + a Galera lib • Is High Available solution for MySQL • One way to scale your DB Layer

• What is NOT: • NOT Oracle MySQL Cluster • NOT Drop-in MySQL replacement

Cluster as a meeting• All current cluster members are in the room

• They all hear what is happening

• New members must be brought up to speed (SST)

• State Snapshot Transfer

• Members that leave temporarily must be caught up (IST)

• Incremental State Transfer

• Only members in the room count in the cluster

Node Types

• Data Nodes • mysqld

• Galera (shared library in mysqld)

• Arbitrator Nodes • just Galera

• replication, no mysqld

• No controllers, admin, config nodes

www.percona.com

Node failure

• Node failure == timeout • writes pause

• Split brain protection

• Only the majority of the cluster

will continue

• Minority will refuse queries

• All-down needs “bootstrap"
