Native MySQL replication is simple and free, but can it handle recovery easily? What about complex topologies or advanced features like heterogeneous MySQL replication, read/write splitting, and seamless failovers? Watch this webinar where we compare MySQL native replication against Tungsten Replicator and Tungsten Clustering. AGENDA - What native MySQL replication is (and isn’t) - Fan-in/fan-out topologies - Heterogeneous MySQL replication - Powerful filtering functionality - Clustering for High Availability (HA) / Disaster Recovery (DR) and zero-downtime maintenance

• It’s easy to setup and it’s free
• Embedded within MySQL Engine
• One-to-Many Topology only
• Parallel Threads by Schema
• Stale reads possible on slave
• No easy mechanism to failover
• Manual operation required to switch roles
• Only Basic Include/Exclude filtering available
• Many additional components required to function as a fully fault tolerant cluster
• MySQL to MySQL Only

• Open Source (free!!) and Commercial Builds available
• One-to-Many / Many-to-One Topologies
• Parallel Threads by Schema
• Complex filtering
• Heterogeneous replication
– Extract from MySQL (Incl RDS and Google SQL) or Oracle
– Apply to MySQL (Incl RDS and Google SQL), Oracle, Redshift, Vertica, Hadoop, Mongo, Elasticsearch,
Kafka (and more coming soon)

Logging
Option 1: Local Install
Extractor reads directly
from the logs, even when
the DBMS service is
down. This is the default.
Option 2: Remote
Extractor gets log data
via MySQL Replication
Slave protocols (which
requires the DBMS
service to be online). This
is how we handle RDS
extraction tasks.

11. Filtering with Tungsten Replicator

12. Types of Filters
1212
• Auditing – Can be used for tracking database updates
• Content – Modify contents of transactions, such as enumerating integers or remove columns,
tables, or schemas
• Logging – Log information about transactions in replicator log file
• Optimization – Optimize statements and improve speed of updates on destination
• Transformation – Rename, reformat schemas and tables, even merge schemas into a single
schema
• Validation – Validation and Consistency checking of data
• Miscellaneous – Others
• Over 40 filters included with Tungsten Replicator which can be ordered as desired!

13. Popular Filters
1313
• DatabaseTransform filter – rename databases or tables, supports regex
• InsertOnly filter – filter to include only “INSERT” events, ignoring others
• ReplicateColumn filter – replicate columns, either by inclusion or by exclusion
• Replicate filter - explicit inclusion or exclusion of schemas and tables to replicate. Can use
wildcards
• SkipEventsByType filter – skip events for entire schemas or tables. For instance, skip all
deletes to SALES.INVOICE
• TimeDelay filter – delays writing events to THL. Allows having a slave that is behind the
master for a specified time period.
• SkipRowByData – replicate rows matching a condition

• Sits outside the MySQL Engine
• Uses Commercial release of Tungsten Replicator at its core
• Connector layer provides transparent read/write splitting
• Automatic Failover
• Simple, single command to switch masters
• Tungsten Replicator can be used to provide cluster-slaves
• Add/Remove nodes to scale reads
• Zero Downtime Maintenance
• Works with all “flavours” of MySQL (Community, Oracle, Percona and Maria)
• Multi-Master and Composite Topologies for expanding HA/DR capabilities
