New replication features in MySQL 5.6

This post was thought of as an attempt to make some performance test with new multi-threaded replication in 5.6, at least that was my initial intention. Based on Luis Soarez – Replication Team Leader in Oracle – post. I wanted to play with new set of variables and features in order to understand how new multi-threaded replication works and make some performance tests.

Taming Pod::Weaver

Pod::Weaver, which does to POD what Dist::Zilla does to distribution files, is all that, only moreso. But it feels so powerful, holds so much promises to make my life easier once I manage to master it, that I won’t let the steep learning curve deter me. I’ll climb down my brain bicycle, and push it up that hill. And I’ll provide a running (well, walking slowly) commentary as I go along, in the hope that it’ll help other peeps who might want to venture is those exciting yet dark waters. Okay. Enough preamble. Let’s get cracking.

Alex Gorbachev Presenting at TOUG’s DD Day

‘m going to be presenting two of my OOW11 sessions at the Toronto Oracle User Group’s DD Day. I’m going to be presenting two sessions, Is Oracle Exadata for You? Starring Roles for the Best Technology, and Under the Hood of Oracle ASM: Failability Analysis.

Cloudy End to a Roller Coaster Week at OOW

Pythian’s presence at OOW each year permits this fine company, of which I have been a part for a total of close to 8 years, to get higher on Oracle’s and the industry in general’s radar. There are so many differentiators that separate Pythian from other companies. Take homes from OOW?

Oracle Database Cloud Services: A Few Initial Thoughts

The website for Oracle Database Cloud Services is now online. It’s a hosted database service running Oracle 11gR2. The database can be accessed using a hosted Oracle application server, via JDBC across the Internet, or their own RESTful API a la Amazon. Notably lacking is Oracle’s own TNS network protocol. A lot of the feature set seems to be oriented toward data warehousing applications, including the aforementioned partitioning, bitmap indexes, query rewrite, and star transformations. A few other interesting features

Oracle Open World Has Been Just That

After the first day and a half, the show has yet again lived up to all expectations. Oracle has been around for over two decades and this well-oiled machine excels at everything it does … OOW 2011 being a living/breathing example. It all started with the database and everything they have touched since has turned to gold.

Hadoop and NoSQL Mythbusting

With all the buzz in OOW about the big data machine, there was also a lot of non-sense flying around. I love it that the Oracle community is finally interested in Hadoop and NoSQL, but I hate it when people sound authoritative without having an actual clue. I’ve left a few presentations with smoke coming out of my ears. Here are few things that people got all wrong

Oracle’s Big Data Machine – Details and Musings

Oracle announced the Big Data Appliance on Monday morning keynote. Many people, me included, were long waiting for this to happen. Others didn’t think it will ever happen. So naturally, there is a lot of buzz and excitement around the new device in Open World. The keynote announcement was very short on details and certainly did not satisfy my technical curiosity. So I went to a few presentations to hear what exactly is included in the offering. Here’s what I found out.
