Description

Drupal is an open-source CMS that has a huge user base and community. I recently managed the MySQL side of the equation for a Drupal-based website of a large television brand. There are some documents out there for high performance MySQL with Drupal, I found them lacking. So I did extensive benchmarking, and profiling of queries, to find the best overall setup.

Session type: 45 minute conference session

Topics: Business and Case Studies

Abstract

Drupal is the open-source CMS du-jour. It has become very popular very quickly, but performance isn’t necessarily tip-top out of the box.

In our implementation of MySQL for a drupal-based website of a large television brand, we went down the path of doing our own benchmarking for our expected pageviews, and ares of the site we thought would get the most traffic. We benchmark the base set of modules, and our own extensions as well using apachebench, http_load, supersmack, and sql-bench. We then optimized the queries inside those modules using various MySQL profiling tools such as EXPLAIN, innotop, slow query log, and show status.

In this presentation we discuss the site, the business requirements, the benchmarking tools, profiling tools, and the final results. It provides a window into the workings of a large high-traffic internet website.

Description

MySQL has a number of great features for managing archival data, and very large tables. We look at the MERGE storage engine first. Then we look at views which can hide many tables behind the scenes. And lastly we look at partitioned tables.

Session type: 45 minute conference session

Topics: Data Warehousing and Business Intelligence

Abstract

MySQL has some very powerful features for large databases now available in 5.1.

We’ll look at the MERGE storage engine first. Then we’ll take a look at views, and the strengths and weaknesses there. And lastly we’ll consider partitioning as an option.

Each of these solutions has pros and cons. When you consider performance, ease of administration, and manageability, they all have tradeoffs.

Description

MySQL Replication is powerful technology, but many things can trip you up. Sometimes the slaves get out of sync with the master, or dump errors into their logfiles. Sometimes replication just can’t keep up. In this presentation will explain how to verify with checksums, avoid traps in your code, monitor, and even help you improve the performance of your replication setup.

Abstract

There are a few big gotchas with MySQL’s statement based replication. Non-deterministic functions can cause the slave to get out of sync, mixing innodb and MyISAM tables, to name just a few. What you need to do is watch for errant and incompatible SQL, and then verify that your setup is correct. Verification can be done with checksums on the tables, and comparing those against the slave copies.

We’ll discuss all this, and the tools and techniques you can use to bulletproof your own replication setup. We’ll also discuss performance tuning. If your slave is getting slowly further and further behind, there are techniques, parameters, and re-architecting that can improve its speed and performance.
