This week we have feedback about Gazzang - Gazzang is using encryptfs for their encryption. According to their launchpad project page at https://launchpad.net/ecryptfs, "eCryptfs is a POSIX-compliant enterprise-class stacked cryptographic filesystem for Linux".

The main topic is the 2nd part of events:

What events log and where the event logs are
How errors show up in the error log
How events and their actions get logged to the binary logs (aka events and replication), including how the "ignore" and "do" replication limitations work with events. Manual page: http://dev.mysql.com/doc/refman/5.5/en/stored-programs-logging.html

This week we interview Doron Levari, CEO and co-founder of ScaleBase. ScaleBase transparently scales your database, so you can have many shards without having to code sharding in your application. The sharding is completely transparent to the application. This can be combined with regular replication to have automatic use of a standby if a shard's primary database fails.

This week we speak with Calvin Sun, the Development Manager of the InnoDB Team, and has been working on InnoDB at MySQL and Oracle for 5 years. He mentions that not only is the InnoDB team hiring, but nobody has left the InnoDB team in several years, so the team is very stable.

We grabbed Calvin at OSCon Data, where Oracle announced the new features of MySQL 5.6 released on labs.mysql.com. Remember that the labs releases are for testing only and not supported in production use.

ACID - atomicity, consistency, isolation, durability
BASE- basically available, soft state, eventual consistency (there's also a good article by Lewis Cunningham that explains ACID vs. BASE in the context of cloud computing.
