25. Replication in Trove

26. 8/19/14 tesora.com 26
• Community decided on a versioned approach
• First version is in Juno
• Goal is to provide read replicas for MySQL
• Subsequent releases will add more capabilities:
• Master-master
• Failover
• Multi-zone disaster recovery
• Choice of replication strategies
Replication - Overview

27. 8/19/14 tesora.com 27
• Launch slave from existing master
• Slave bootstrapped with snapshot of master
• Uses MySQL native asynch replication
• Started from snapshot provided binlog position
• Master can support many slaves
• Replication is monitored; instance status changes for delay
or disconnect
• Slaves can be promoted (i.e. detached from Master)
Replication – Juno Capabilities
