o_custkey IN
(SELECT c_custkey FROM customer
WHERE c_address LIKE 'Le%'));

MySQL Enterprise Detail – What’s Next?

Help with scaling your on-line applications!


Scaling with MySQL

Web/App
Servers MySQL Replication

writes

Users/ MySQL
Customers Replication
reads

reads


Common Pain Points
• Application level load balancing is limited to read/write
splitting
– Hardware utilization not optimized
– Reads directed to latent slaves
• Little insight into user/application related activity
– “Evil” queries
– Slow query log good, but not great
• Idle connections on production servers
– Consume resources
– PHP, Ruby, Perl have no built in connection management
– App servers > Db servers = Connection Storm!


MySQL Load Balancer

MySQL Query Analyzer

MySQL Enterprise Monitor feature that allows
users to trace, monitor, and analyze MySQL query
activity for specific servers, users, and
applications.
– Adaptive “Evil” query collection/tracing
– Historical browsing/analysis
– “Needle in a haystack” identification of worst queries
– Worst execution times, # of execs, etc.

SQL code is the #2 cause of performance issues
97% of those surveyed will use this

MySQL Connection Manager
MySQL Enterprise software that maximizes the
efficiency, performance, and scalability of database
connections made by online applications.

Connection Manager
• Comprised of two core features
– Connection Pooler MySQL MySQL
– Connection Concentrator Connection
Pooler
Connection
Concentrator

• Prevents connection “overload” and
“waiting” on database

Optimizes throughput of online applications
Reduces overhead on production servers

Increased Reusable Pool
Utilization of Pooled of Database
Connections via Connections
1000’s of Requests Multiplexing Transactions
onto a Single Connection

Practical Use Cases

• MySQL Load Balancer
– High traffic, read intensive apps and websites
– Application load balancing extension

• Enterprise Monitor w/Query Analyzer
– Shops with rapid development cycles (test = prod)‫‏‬
– Apps with heavy use of dynamic SQL

• MySQL Connection Manager
– Websites that experience frequent or idle connections
• app servers > db servers
• developed in language with no built-in connection management


MySQL Enterprise Roadmap
Allready there
 Monitor 1.3 w/Japanese Localization
 New Advisors and Rules (Upgrade Advisor)‫‏‬
 Monitoring of 5.1
 Monitor 2.0 w/Query Analyzer

Into 2009
 MySQL Load Balancer
 MySQL Connection Manager
 Monitoring of 6.0 and Falcon


Conclusions

• MySQL Server getting more enterprise-class features
• More/better options for high availability implementations
• Improved Data warehousing capabilities
• Continued improvements in MySQL Enterprise services
• More tools to enable MySQL development
