Join Tom Hanlon for a tour of the current landscape.
Demos of each tool wil be shown. Tools of the Trade Part II. Join us for a presentation of the wonderful world of benchmarks and monitoring tools. Here you will learn what is available, how each tool works, and a demonstration using each tool against a running database from a veteran MySQL expert.
A popular and lighthearted session in quiz format. Fun and educational, a broad range of "what not to do" is explored, taking examples from the scary real world. Noted Solaris and DTrace expert Ben Rockwood will show how to evaluate and introspect MySQL's behavior, and gain information that isn't normally attainable by developers and system administrators. Mike Callaghan will describe enhancements to InnoDB that improve its scalability on servers with many disks and many CPU cores, results from benchmarks, and results from production systems.
Investigating Innodb Scalability Limits.
In this presentations we will look into which problems are fixed. Learn about a horizontal scalable architecture for accessing exponentially growing datasets, and performance results obtained on several filesystems, MySQL storage engines, and partitioning. Memcached and MySQL: Everything You Need To Know. This tutorial details how to get started, the ins and outs of deploying Memcached as a key caching layer in your applications, and how to keep scaling. Phorum is the message board software used by MySQL.
One reason they chose Phorum was because of its speed. We have to use some tricks and fancy SQL to make this happen. Learn how. This presentation discusses how MySQL was leveraged to provide a large scale personalization technology platform solution for a site like ebay. The Tobias and Jay Show. In this session we'll put features that do the same thing up against each other and see which performs better. We find the optimal way to do smaller things.
Everything is backed up by benchmarks and discussion. In this presentation learn how MySQL, InnoDB, and Solaris helped Fotolog gain the top performance it desired as the world's largest photo blogging community through tuning and schema optimizations.
Tests were conducted with MySQL 5. Tests were conducted with Oracle 11g and 12c.
Tests were conducted with PostgreSQL 9. Have more questions about SQL indexing or tuning? No problem—have a look at my training and tuning services at winand.
Anatomy of an Index — What does an index look like? The Leaf Nodes — A doubly linked list. Slow Indexes, Part I — Two ingredients make the index slow. The Where Clause — Indexing to improve search performance.
The Equals Operator — Exact key lookup. Primary Keys — Verifying index usage. Concatenated Keys — Multi-column indexes. Functions — Using functions in the where clause.
User-Defined Functions — Limitations of function-based indexes. Over-Indexing — Avoid redundancy. Bind Variables — For security and performance. Searching for Ranges — Beyond equality. Index Combine — Why not using one index for every column? Partial Indexes — Indexing selected rows.
Emulating Partial Indexes — using function-based indexing. Obfuscated Conditions — Common anti-patterns. Numeric Strings — Don't mix types. Combining Columns — use redundant where clauses.
Testing and Scalability — About hardware. Data Volume — Sloppy indexing bites back. System Load — Production load affects response time.
Response Time and Throughput — Horizontal scalability.
