Dynamic Active/Active (DAA)
• New topology
• Cluster is Active/Active
• Connectors configured with view of Active/Passive
• Removes the need for “switchover” to activate remote cluster
• “Quick failover”
• Avoids risks of Active/Active such as data conflicts
• Connector intelligence to re-direct write traffic
• Optionally auto failback after cluster recovery
• Enable simply by configuring connector affinity
• connector-write-affinity=alpha,beta
• https://docs.continuent.com/tungsten-clustering-7.0/deployment-dynamicactiveactive.html

9. The MySQL Availability

Distributed Datasource Groups
• Automatic failover between regions/datacenters
• Create Datasource Group, assign nodes to groups
• Failovers happen within a group
• Failover will promote a replica in another group if no
candidates in local group
Distributed Datasource Groups

10. The MySQL Availability
Company
Connector in Docker
• Available from v7.0.3 onwards
• Available NOW to all licensed clustering users
• Download from website portal
• Easy to deploy and configure
• Full SSL support

Backup & Recovery
• tprovision
• Was tungsten_provision_slave prior to v7
• New backup method: rsync
• 2 passes to copy Database files at the filesystem level
• First pass “seeds” the target by simply copying while source is online
• Second pass locks the source for writes, then does file copy
• This 2-pass method reduces source database lock time
• Target can be seeded prior, allowing a quick maintenance window for the 2nd pass
• Supports primary and replicas as sources (but could affect application if primary is used as
a source due to database lock!)
• New backup method: mysqlclone
• Now supports MySQL data/log/undo files in separate directories
• Improved logging and error handling

12. The MySQL Availability
Company

• Prometheus is used to collect metrics
• Grafana is used to visualize metrics
• Visualize metrics in the Grafana panel of Tungsten Dashboard
• Add notes for any node
• Ability to create audit trail of all updates
• Ability to highlight rows of nodes where replicator is lagging by a user specified number of seconds
• Display API calls if desired –useful for transparency and learning
• Performance tweaks for low bandwidth links and administration of many clusters

13. The MySQL Availability
Company
Additional Features and Enhancements
• tungsten_purge_thl – intelligently purge THL cluster-wide
• tapi – easy command line access to APIv2
• THL compression and encryption on disk
• Audit logging now available for the connector
• Connector drain feature – gracefully stop the connector by preventing new connections and waiting
for in process connections to finish
