Managing
         PostgreSQL
         Replication



© 2ndQuadrant Limited 2010
Who Am I?
       • Simon Riggs
       • Major Developer on PostgreSQL project
       • CTO, 2ndQuadrant




© 2ndQuadrant Limited 2010
Replication Use Cases
       • High Availability   • Protection
                             • Total Cost of
       • Scalability             Ownership
                             • Exploiting success




© 2ndQuadrant Limited 2010
Replication Mechanisms
       • Trigger-based replication
                 – User space solution
       • Log-based replication
                 – Integrated development




© 2ndQuadrant Limited 2010
Log Shipping Developments
       • 8.0 – Point in Time Recovery, Full WAL info
       • 8.2 – Restartable Recovery, Log Switching,
               Streaming API
       • 8.3 – Full Page Optimization, pg_standby
       • 8.4 – BgWriter during Recovery
       • 9.0 – Streaming Replication
               Hot Standby



© 2ndQuadrant Limited 2010
Streaming Replication (9.0)
       •      Efficient real-time “log shipping”
       •      Master → Slave replication using full security
       •      Multiple concurrent slaves
       •      Robust bi-modal design

Hot Standby
       •      Read-only access while “in recovery”
       •      Equivalent of Oracle 11g Active Data Guard
       •      Load balanced read scalability
       •      Query off-load from main write node
       •      Multiple highly available standby nodes




© 2ndQuadrant Limited 2010
Capabilities
       •   High Performance
       •   Integrated
       •   Ease of Use
       •   Query Access
       •   Relay
       •   Selectivity
       •   Query Farm

Capabilities with Tools
       •   High Performance
       •   Integrated
       •   Ease of Use
       •   Query Access
       •   Relay
       •   Selectivity
       •   Query Farm


© 2ndQuadrant Limited 2010
Repmgr




© 2ndQuadrant Limited 2010
Repmgr
       • Simplify standby management
       • Monitor replication delays
       • Provide feedback mechanisms




© 2ndQuadrant Limited 2010
Future: Sync Replication (9.1)
       •   User-controlled robustness
       •   High performance design
       •   Simplicity
       •   Additional flexibility through registration




© 2ndQuadrant Limited 2010
Future: Loose Coupling
       •   Allows distributed database
       •   High Availability and Disaster Recovery
       •   No shared resources – better scalability
       •   “Cellular” approach
