There was a lot of news this week! There were three really big announcements at Oracle OpenWorld that relate to the MySQL community:

Oracle released a NoSQL database. http://www.oracle.com/technetwork/database/nosqldb/overview/index.html
It’s an ACID-compliant key-value data store, with a Java API for put, delete and get operations and includes replication. The data partitioning and distribution is automatic and based on a hash function.

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.

Nick Pisarro, aka @highenergybeams, suggested we do a podcast about the MySQL defaults we recommend always having, as MySQL's pre-configured option files are not particularly helpful. So we have put together a 2-part podcast on the options that we change.

Location and precedence of configuration files for Windows, Unix and Mac OS X:
