4. Pain Points – The Scalability Problem
• Thousands of new online and mobile
apps launching every day
• Demand climbs for these apps and
databases can’t keep up
• App must provide uninterrupted
access and availability
• Database performance and
scalability is critical

7. Methods and Challenges to Scale Out MySQL
• August 16 and September 20, 2012
– Scaling MySQL: ScaleUp versus Scale Out: This webinar will
examine best practices around scaling MySQL databases
• Today
– Methods and challenges to Scale out MySQL
• November 15, 2012
– Catch 22 of read-write splitting
• December 13, 2012
– Automated data distribution

8. Scale Up Pros & Cons
Pros Cons
May result in major performance Tedious, never ending…
improvements
Mostly transparent to the application SQL modifications are not always an option
HW upscale is easy Expensive
Requires unique skill set
Requires downtime
Limited. At one (near) point – the database engine
itself becomes the bottleneck
8

9. The Database Engine is the Bottleneck...
• Every write operation is At Least 4 write operations inside the DB:
– Data segment
– Index segment
– Undo segment
– Transaction log
• And Multiple Activities in the DB engine memory:
– Buffer management
– Locking
– Thread locks/semaphores
– Recovery tasks

10. The Database Engine is the Bottleneck
• Every write operation is At Least 4 write operations inside the DB:
– Data segment
– Index segment
– Undo segment Now multiply
– Transaction log by 10TB
accessed by
• And Multiple Activities in the DB engine memory:
10000
– Buffer management

– Locking
sessions
– Thread locks/semaphores
– Recovery tasks

11. Scale Out (two methods)
Read
Write
Read/Write
1
Splitting
Replication
Automatic Data
2
Distribution
11

12. Read/Write Splitting
• Good for scaling high session-volume reads
• Limited in scaling high data-volume reads
– Replication of data-volume is costly
– Queries balanced to the slave, still meet big data
• Limited in for scaling writes
• Home-grown implementations have drawbacks
12

13. Scale Out Features and Benefits
Feature Benefit
Replication lag-based routing Improves data consistency and isolation
Read stickiness after writes Ensure consistent and isolated database operation
100% compatible MySQL proxy Applications unmodified
Standard MySQL tools and interfaces
MySQL databases untouched Data is safe within MySQL InnoDB/MyISAM/any
Real-time monitoring and alerts Simplify management, reduce TCO
13

14. Automatic Data Distribution
• The ultimate way to scale
• Provides significant performance improvements
• The only way to really improve read and also writes
• Good for scaling high session-volume reads and writes
• Good for scaling high data-volume reads and writes
• Home-grown implementations have drawbacks

15. Scale Out Features and Benefits
Feature Benefit
Parallel query execution Great performance of cross-db queries &
maintenance commands
Query result aggregation Support of sophisticated cross-db queries, even with
ORDER BY, GROUP BY, LIMIT, Aggregate functions…
Online data redistribution Flexibility: no need to over-provision
No downtime
100% compatible MySQL proxy Applications unmodified
Standard MySQL tools and interfaces
MySQL databases untouched Data is safe within MySQL InnoDB/MyISAM/any
Data distribution review and analysis Optimization of data distribution policy
Data consistency verifier Validate system-wide data consistency
Real-time monitoring and alerts Simplify management, reduce TCO

21. Summary
• Database scalability is a significant problem
– App explosion, Big Data and mobile compound it
• Scale Up helps somewhat, but Scale Out provides
a longer term and more cost effective solution
• ScaleBase has an effective scale out
solution with a proven ROI
– ScaleBase improves performance
and requires NO changes to
your existing infrastructure
• Choose your scale-out path....
– ScaleBase is a platform that enables
you to start with R/W splitting and
grow into data distribution
