seen that we have a way of deploying a topology where all nodes
are masters, and achieve better efficiency and stability than
ring topologies. That …

Here at VividCortex, it’s clear to us that proper database monitoring is “an art.” Beyond simple, raw power, navigating and understanding a database takes finesse, insight, and, often, a kind of eloquence.
On special occasions, though, the artistry of database monitoring becomes a little bit more literal, and we get to see how the functions of big data can be applied to the actual world of Fine Art. Such is the case now: this summer, New York’s world-class Museum of Modern Art (MoMA) decided to publicly post an enormous CSV file on GitHub, which contains various data sets for more than 125,000 pieces in the museum’s collection.
Essentially, with this document, a scholar, museum guest, or artist now has access to huge swaths of information about the art at MoMA – short of an image of the piece itself. While the ultimate experience for most …

While selling free software sounds like a hard job, the growing mainstream adoption of open source makes it one of the most exciting segments in IT. In my daily meetings with customers, there is no ambiguity that open source is the foundation for the hottest trends in technology, including Cloud, Analytics, Mobile and Social. Gartner reports that 70% of all new applications are built using an open source database. (1)
Yet until now, many customers had to make compromises related to leveraging the innovation, high-quality code, lower costs, and choice inherent in open source, versus leveraging highly secure, scalable and power efficient enterprise-class z Systems offered by IBM.
Today at LinuxCon North America that changes. We at …
[Read more]Giuseppe and Shlomi both blogged on one of the recent changes introduced to MySQL 5.7.8-rc, where the setting show_compatibility_56 is now set OFF by default.
Both raise very good points. Here is how we plan to address them:
Today’s topic is related primarily to compiling MySQL from source using CMAKE and what kind of issues we encounter during this task. We want to install MySQL 5.6.19 with Debug+Valgrind etc. On CentOS 7 here are my dependency packages start point:
[root@centos-base ~]# yum install zlib zlib-devel openssl openssl-devel valgrind valgrind-devel cmake gcc cpp ncurses ncurses-devel
Here is my CMAKE command:
[root@centos-base mysql-5.6.19]# cmake -DCMAKE_INSTALL_PREFIX=/opt/mysql-5.6.19 -DMYSQL_DATADIR=/var/lib/mysql -DSYSCONFDIR=/opt/mysql-5.6.19 -DWITH_SSL=system -DMYSQL_TCP_PORT=3306 -DMYSQL_UNIX_ADDR=/opt/mysql-5.6.19/mysqld.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_DEBUG=1 -DCOMPILATION_COMMENT="Shahriyar Rzayev's CentOS MySQL-5.6.19" -DOPTIMIZER_TRACE=1 -DWITH_ZLIB=system -DWITH_VALGRIND=1 -DCMAKE_C_FLAGS=-DHAVE_purify -DCMAKE_CXX_FLAGS=-DHAVE_purify
