Hints & Tips

White Paper: MySQL Cluster for Presence & Location-Based Services

This whitepaper explores the different types of services that can take advantage of location and presence awareness, and considers their unique requirements for data management. A solution is then presented, based on MySQL Cluster, that allows operators to fully leverage the market opportunity and differentiation presented by these new services.

PlanetMySQL Blog: Simple lessons in improving scalability
Ronald Bradford

It can be very easy to improve scalability with a MySQL server by a few simple rules. Here is one of them -- "the most efficient way to improve an SQL statement is to eliminate it".

PlanetMySQL Blog: Upgrading passwords from old_passwords to "new passwords"
Shlomi Noach

You have old_passwords=1 in your my.cnf. I'm guessing this is because you used one of the my-small.cnf, my-large.cnf etc. templates provided with your MySQL distribution.

PlanetMySQL Blog: Checkpoint handling enhancements in Cluster 7.1 -or- *Ding Dong* GCP Stop is dead!
Matthew Montgomery

One of the tasks that a data node must perform reliably is the Global Check Point. That is, to flush the transaction redo log to disk. The GCP completion must be synchronized on all data nodes in order to maintain a consistent end point for recovery.

PlanetMySQL Blog: PHP: Application calling plugin - on communication
Ulf Wendel

Imagine PECL/mysqlnd_ms could keep certain reads on certain slaves in a MySQL master-slave setup. You would have a good chance to profit from hot database caches. You would not only distribute read load, scale out horizontally by using MySQL replication, you would also optimize your reads for hot caches.

PlanetMySQL Blog: MySQL Semi-Synchronous Replication. See the Magic. Try the Magic.
Ronen Baram

MySQL Replication is one of the most used and valued features of the MySQL Server. Unlike some other products on the market, it's out-of-the-box, easy to configure, non-paid and smart features. Most of our medium/large/super-large installation base are using replication to achieve "scale-out" scaling.

PlanetMySQL Blog: PHP: want transparent master slave load balancing in mysqlnd?
Ulf Wendel

Are you interested in a master slave load balancing plugin for mysqlnd? It could have two operational modes. The automatic mode would operate transparent from an applications point of view. The manual mode would give you full control over all decisions. Automatic mode is for install and forget when you start with MySQL replication. Manual mode is for growing as your application evolves.

PlanetMySQL Blog: VIEWS on INFORMATION_SCHEMA tables - Useful stuff
Anders Karlsson

Views in MySQL really has quite a bad reputation, for bad performance mainly, but also there were some stability issues at some point. Now they are pretty stable, but I don't see them used that much. One place where I like to use them myself is in combination with INFORMATION_SCHEMA tables. The I_S tables are really useful and contain a lot of information, and by using VIEWs we can massage the data a bit.

PlanetMySQL Blog: How to detect if a MySQL server is an active replication slave
Giuseppe Maxia

Sometimes you know for sure. And sometimes you wonder: is this server part of a replication system? And, most specifically, is it an active slave? The completeness of the answer depends on how much visibility you have on the server.

PlanetMySQL Blog: Using SQL to create SQL (and other usefulness)
Sarah Novotny

Today, I had a task of modifying a slave to exclude (or if you want to say specifically include) tables. The situation is that this slave needs to only contain tables used for reporting. The added benefit is that with fewer tables to replicate, there will be less replication traffic, less disk I/O and less disk space used hence better performance for queries that digest statistical data.

PlanetMySQL Blog: MySQL Enterprise Backup 3.5, the crash course
Ronen Baram
