The ability to replicate from one MySQL server to another is a well established and proven technology. Until recently, replication from a MySQL server to an external application was not supported. This technology would not only enable a universe of applications, it would also permit developers to integrate near real time data changes from MySQL quickly and reliably into their own solutions.
Erlang can be used to build fault tolerant systems with a fraction of the effort needed when using conventional languages. The trick is avoiding defensive programming while focusing on the correct case. This hands-on tutorial will go through the Erlang constructs and libraries that provide the building blocks used to develop reliable systems that never fail.
We at DeNA (largest social game provider in Japan) handle over 2
billion page views per day with MySQL. We heavily use SSD and tune
Linux. We run non-trivial solutions such as non-stop, automated MySQL
master failover. We also use MySQL not only as traditional RDBMS but
also an extremely high performance NoSQL. I'd like to introduce our
MySQL solutions to make our social games scale better.
