MySQL Performance Analysis with Percona Toolkit and TCP/IP Network Traffic

The TCP network traffic conversation between a client and a MySQL server is a rich source of data for many types of analysis. In this paper, we show how the simplest type of traffic packet headers with no payload can provide a surprising variety of information about the system’s performance. The techniques that we demonstrate are quick, require o - Read More

Causes of Downtime in Production MySQL Servers

Everyone wants to prevent database downtime by being proactive, but are measures such as inspecting logs and analyzing SQL really proactive? Although these are worthwhile, they almost always identify problems that already exist. To be truly proactive, one must prevent problems, which requires studying and understanding the reasons for downtime. T - Read More

Preventing MySQL Emergencies

Preventing downtime-causing emergencies in MySQL can be difficult because they are caused by complex combinations of several things going wrong. Efforts to be proactive may be sincere, but without knowledge of the causes of emergencies, they often fail to prevent further problems. This white paper explains dozens of ways that real emergencies coul - Read More

Scaling MySQL Deployments With Percona Server and Virident tachIOn Drives

Until recently, MySQL and InnoDB were unable to take advantage of high-performance hardware, particularly storage systems. Large-scale deployments made heavy use of so-called horizontal scaling with a technique called sharding — partitioning data across many small-to-midsize servers. Today, MySQL — especially Percon - Read More

Configuring Percona Server with XtraDB for Fast Restarts

InnoDB requires a long time to restart on servers with large amounts of memory. It can take many hours to warm InnoDB up enough to serve queries quickly. The database's "working set" of data is not in memory after a restart, so queries must perform random disk I/O to read pages, and are thus too slow for production use. Percona Server with XtraDB g - Read More

Forecasting MySQL Scalability with the Universal Scalability Law

Forecasting a system's scalability limitations can help answer questions such as “will my server handle ten times the existing load?” and “at what point will I need to upgrade my hardware?” Timely answers to these questions have more business value than exact predictions. Mathematical models can help reduce guesswork while - Read More

Percona Server with XtraDB for Software-as-a-Service Application Databases

The Software as a Service (SaaS) deployment model is popular with customers, but SaaS databases are often difficult for providers to manage, due to the unique stresses placed upon them. The open-source MySQL database server can suffer from performance and operational limitations in SaaS deployments. Percona Server with XtraDB is an enhanced versio - Read More
