Three rules on making indexes around queries to provide good performance

Application performance often depends on how fast a query can respond and query performance almost always depends on good indexing. So one of the quickest and least expensive ways to increase application performance is to optimize the indexes. This talk presents three simple and effective rules on how to construct indexes around queries that result in good performance.


Time: 2PM EDT / 11AM PDT

This webinar is a general discussion applicable to all databases using indexes and is not specific to any particular MySQL® storage engine

Consolidating MariaDB project tools

It is not a secret that we’ve been kicking the tires and playing with JIRA for project management. After using it since the beginning of the year most of us like the feel of it and we’ve decided that it makes sense to start using it more.

As you know, the MariaDB project has many fragmented resources. We report bugs in Launchpad. We store our plans in worklog. We’ve never used the Launchpad Blueprint feature for this very reason. We don’t use Launchpad Answers because we have the Knowledgebase.

With this move to hosted JIRA (yes, this is an important link: http://mariadb.org/jira) we can

Monty Program & SkySQL: a statement on the serious security vulnerability that was found in MariaDB and MySQL
+5 Vote Up -0Vote Down

Over the past few days extensive conversations around a new security vulnerability in MariaDB and MySQL have taken place.

It all started as a chain reaction when Monty Program publicly disclosed information about the flaw they had found and about how to make sure your MariaDB and MySQL installations can be fixed. The initial information got assigned the security vulnerabitlity identifier CVE-2012-2122 and the contents can be seen e.g. here http://seclists.org/oss-sec/2012/q2/493.

The bug was found two months ago on April 4th.

Before disclosing the information publicly, given the seriousness of this bug and considering the millions of MySQL and MariaDB installations deployed worldwide, Monty Program informed the biggest distributors of MySQL and

Webinar: TokuDB v6 Replication Performance
+1 Vote Up -0Vote Down

TokuDB® is a proven solution that scales MySQL® and MariaDB® from GBs to TBs with unmatched insert and query speed, compression, and online schema flexibility.

Tokutek’s recently launched TokuDB v6 delivers all of these features and more, with the introduction of high performance replication for MySQL and MariaDB. TokuDB v6 eliminates the common and persistent problem of “slave lag” in which a replication server is unable to keep up with the query load borne by the master server. TokuDB v6 solves this by offering high ingestion rates at the slave.

What comes in between MariaDB now and MySQL 5.6?
+7 Vote Up -3Vote Down

We’re quite happy that we’ve released four major releases that are production ready (better known as generally available or GA in the MySQL world) in the last 26 months. That is just a little over two years, and a whole lot of features. In that same time, MySQL has seen one GA release (MySQL 5.5) and we’re all eagerly awaiting the upcoming MySQL 5.6.

You’ll note that we built MariaDB 5.1, 5.2, and 5.3 based on the MySQL 5.1 codebase. A significant number of features went into MariaDB 5.3 (our biggest GA release to date), with the biggest changes in the optimizer in over a decade. There were also many

Challenges of Big Databases with MySQL – IOUG Presentation
+3 Vote Up -0Vote Down

 

 

Many database management tasks become difficult as you move from millions of rows and gigabytes of data to billions of rows and terabytes of data. Such tasks include ingesting data while maintaining indexes; changing schemas without downtime; and supporting connections, replication, and backup. For some scaling problems (connections and replication), MySQL® is better than most of the competition. For others, such as indexing, schema changes, and backup, MySQL has typically been harder to use. Fortunately, the tasks MySQL does well are in its core, whereas the tasks that are more difficult can be solved with storage engine plug-ins.

TokuDB v6.0: Frequent Checkpoints with No Performance Hit
+0 Vote Up -0Vote Down

Checkpointing — which involves periodically writing out dirty pages from memory — is central to the design of crash recovery for both TokuDB and InnoDB. A key issue in designing a checkpointing system is how often to checkpoint, and TokuDB takes a very different approach from InnoDB. How often and how much InnoDB checkpoints is complicated, but under certain workloads it can be relatively infrequent. In contrast, TokuDB runs a complete checkpoint starting one minute after the last one ended.

Frequent checkpoints make for fast recovery. Once MySQL crashes, the storage engine needs to replay the log to get back to a correct state. The length of the log is a function of the time since the last checkpoint for TokuDB and a more complicated function of the workload for InnoDB. And replaying the log is single threaded. So

TokuDB v6.0: Even Better Compression
+1 Vote Up -0Vote Down

A key feature of our new TokuDB v6.0 release, which I have been blogging about this week, is compression. Compression is always on in TokuDB, and the compression we’ve achieved in the past has been quite good. See a previous post on the 18x compression achieved by TokuDB v5.0 on one benchmark. In our latest release, we’ve updated the way compression works and got 50% improvement on compression.

I decided to present numbers on the same set of data as the old post, so see that post for experimental details.

But first, what are the changes? TokuDB compresses large blocks

TokuDB v6.0: Getting Rid of Slave Lag
+1 Vote Up -0Vote Down

Master/slave replication is an important tool that gets used in many ways: distributing read loads among many slaves for performance, using a slave for backups so the master can handle live load, geographically distributed disaster recovery, etc. The Achilles’ Heal of slave performance is that slave workloads are single-threaded. The master can have many clients inserting, updating, querying, whereas the slave has only one insertion client: the master. InnoDB single-client performance is much slower than its multi-client performance, which means that the bottleneck in a master/slave system is often the rate at which a slave can keep up.

If the master has an average transactions per second (tps) that is higher than what the slave can handle, the slave will fall further and further behind. If the slaves are being used to distribute read workload, for example, the

Announcing TokuDB v6.0: Less Slave Lag and More Compression

We are excited to announce TokuDB® v6.0, the latest version of Tokutek’s flagship storage engine for MySQL and MariaDB.
