Description:
markdown
The Drizzle database had its first stable GA release at the start of 2011. Since then we have been working on a few features taht directly relate to be able to easily produce applications that can scale. 1) True mulitenancy. running a database server in a Virtual Machine is an instant way to kill performance. A VM running a database server for each user doesn't scale. Drizzle now has a concept of CATALOGs, this can give each tenant their own namespace for databases, tables and users. 2) Multi-master Drizzle has the ability to replicate from multiple masters, enabling you to pull all your shards into one database for analytics and cross-shard queries. 3) Sharding The Drizzle client library (libdrizzle - which can speak the MySQL protocol to Drizzle and MySQL servers) has new features to help with sharding, being able to connect to a shard, a read-only replica of a shard as well as supporting moving shards between machines and adding more capacity.
