I promised to write little articles about all storage engines which sessions I attended during MySQL Users Conference but I did not get too far yet, too busy. So today it is time for PBXT. I was very interested about session about PBXT because this is storage engine does not target the same general purpose […]

I was reviewing the Percona Live sponsors list the other day and pondering the potential success stories associated with this product or that one…. and as I was preparing to put more thought on the topic, a PlanetMySQL post caught my eye. It was penned by Mike Hogan and titled, “Thoughts on Xeround and Free!” […]
In preparing for this month’s Percona Live MySQL Conference and Expo, I’ve been reminiscing about the annual MySQL User Conference’s history – the 9 times it previously took place in its various reincarnations – and there are a lot of good things, fun things to remember. 2003 was the year that marked the first MySQL user conference […]
This is the second in a series on what’s seriously limiting MySQL in certain circumstances (links: part 1). In the first part, I wrote about single-threaded replication. Upstream from the replicas is the primary, which enables replication by writing a so-called “binary log” of events that modify data in the server. The binary log is […]
Finally I was able to run PBXT 1.0.11 pre-GA in tpcc-like workload, apparently there was bug with did not allow me to get the result earlier, and I am happy to see that PBXT team managed it. For initial runs I took tpcc 100 warehouses ( about 10GB of data) which fully fits into memory […]
Following on from our earlier announcement, Paul McCullagh has responded with the answers to your questions – as well as a few I gathered from other Percona folks, and attendees of OpenSQL Camp. Thank you Paul! Whatâ€™s the “ideal” use case for the PBXT engine, and how does it compare in performance? Â When would I […]
OK, I am not getting too much people feedback on what would they like to hear about on MySQL Users Conference, so I went ahead and submitted few presentation ideas. I do not expect all of them would be accepted, furthermore it would be hard to prepare so many good presentations if they are so […]
Quite frequently I run into question like this “I’m using SQL_NO_CACHE but my query is still much faster second time I run it, why is that ? The answer to this question is simple – because SQL_NO_CACHE only bypasses query cache but it has no change on other caches, which are MySQL Caches – Innodb […]
I finally found a time to publish Landscape of Transactional Storage Engines slides on MySQL Presentations page , this is the talk which we gave on OSCON 2007 and which talks about current state behavior and performance properties of Innodb, Falcon, PBXT and SolidDB Storage Engines.
The PBXT Storage Engine (http://www.primebase.com/xt/) is getting stable and we decided to benchmark it in different workloads. This time I tested only READ queries, similar to ones in benchmark InnoDB vs MyISAM vs Falcon (http://www.percona.com/blog/2007/01/08/innodb-vs-myisam-vs-falcon-benchmarks-part-1) The difference is I used new sysbench with Lua scripting language, so all queries were scripted for sysbench.
