“Legacy MySQL does not scale well on a single node, which forces granular sharding and explicit application code changes to make them sharding-aware and results in low utilization of severs”– Dr. John Busch, Schooner Information Technology A super-set of MySQL suitable for Big Data? On this subject, I have interviewed Dr. John Busch, Founder, Chairman, [...]
Typical MySQL environment involves one Master receiving writes and multiple slaves to scale the reads. The “slave” term has been used in MySQL because the Slave servers have to perform every task in copying from the Master binlog, then updating their relay logs and finally committing to the Slave databases. The Master plays no role in replication here other than storing the replication events in the binlog.
With this kind of Master- Slave set up, there are several limitations-
- Slave lag - Stale or old data - Data loss - Manual failover which is error-prone and time consuming
In SchoonerSQL, there is no concept of “Slaves” inside synchronous cluster. We refer to it as "Read Masters" because of our synchronous approach and different replication architecture. It is …

By now you are probably aware that the European Commission has decided to launch an extended investigation into Oracle’s acquisition of Sun based on concerns over MySQL.
The new has prompted a lot of criticism of the EC, much of it suggesting that the delay will do considerable harm to Sun (and therefore Oracle). This argument is valid - Sun’s already declining revenue has been in freefall since the deal was announced and one wonders how far it will fall in another 90 days of stasis.
Other criticism, (such as this from Matt Asay) focuses on the suggestion that the delay will do little to help MySQL or its users, and that the EC fails to understand open source.
This also has some …[Read more]

Ryan posted an article on the MySQL Performance Blog about how to use mk-query-digest to analyze and understand your memcached usage with the same techniques you use for MySQL query analysis. This is an idea that came to me during the 2009 MySQL Conference, while talking to our friends from Schooner, who sell a memcached appliance.
It suddenly struck me that the science of memcached performance is basically nonexistent, from the standpoint of developers and architects. Everyone treats it as a magical tool that just performs well and doesn’t need to be analyzed, which is demonstrably and self-evidently false. memcached itself is very fast, true, so it doesn’t usually become a performance bottleneck the way a database server does. But that’s not the point. There is a …[Read more]
There has been a significant increase in interest in the Memcached, the open source distributed memory object-caching system, in recent months, as a number of vendors look to exploit its popularity in Web 2.0 and social networking environments.
Like Hadoop, which has become the focus of a number of commercial plays, it would appear that the time is right for commercialization of Memcached. But what is it, here did it come from, and what are the chances for vendors to rake in serious cash? Here are the details.
What is it?
Pronounced mem-cash-dee, Memcached was originally created by Danga Interactive (the developer of LiveJournal, which was acquired by Six Apart in 2005) to speed up the performance of dynamic Web applications by alleviating database load. Memcached has become an industry standard for improving the performance of dynamic websites.
The code is available from the …[Read more]
