(Shlomi Noach) SQL is not meant to generate graphics, for sure; but I see some cases where generating non-tabular output can be desirable, as I will show in future posts.

Finding queries with duplicate columns
(Baron Schwartz) A while ago I wrote about a tool to help make upgrades safer. Since then, we have gotten several people to help sponsor development on this tool, and a few of our customers are using it to help find problems before they upgrade their systems.
MySQL Proxy: profiling 0.8
(jan.kneschke) In MySQL Proxy 0.8 we are added a multi-threaded network-subsystem allowing several networks events be processed in parallel. Early benchmarks show that what we have in trunk basicly works.
Why you don’t want to shard.
(Morgan) The Percona training workshop will not cover sharding. If you follow our blog, you’ll notice we don’t talk much about the subject; in some cases it makes sense, but in many we’ve seen that it causes architectures to be prematurely complicated.
Better Primary Keys, a Benefit to TokuDB’s Auto Increment Semantics
(Zardosht) In our last post, Bradley described how auto increment works in TokuDB. In this post, I explain one of our implementation’s big benefits, the ability to combine better primary keys with clustered primary keys.
Setting up MySQL Asynchronous Replication for High Availability
(Andrew Morgan) MySQL replication is often positioned as a solution to provide extra throughput for your database (especially when dealing with high numbers of read operations). What tends to be overlooked is how it can be used to provide high availability (HA) – no matter how much redundancy you ha
Reasons to use InnoDB Plugin
(Shlomi Noach) I wish to present some compelling reasons to use the InnoDB plugin. The plugin is a drop-in replacement for “normal” InnoDB tables; enabling many new features. It is the outcome of a long termed silence from InnoBase (Oracle), which were thought to be neglecting the InnoDB engine.
Copying InnoDB tables between servers
(Vadim) The feature I announced some time ago http://www.mysqlperformanceblog.com/2009/06/08/impossible-possible-moving-innodb-tables-between-servers/ is now available in our latest releases of XtraBackup 0.8.1 and XtraDB-6.
Use of OUT and INOUT Parameters
(Leo Hsu and Regina Obe) PostgreSQL has supported what are called Out (output) parameters since version 8.1. We were surprised it has been that long since we always thought of it as a feature from 8.2+ until it recently came up for discussion on PostGIS newsgroup and we decided to investigate how lo
MySQL Cluster Data Node restart times
(Andrew Morgan) Restarts are required for certain, infrequent maintenance activities. Note that there is no loss of service while a single node restarts.
