Abstract
Techniques and mechanisms described herein facilitate the management of data centers. According to various embodiments, a first query dispatcher at a first data center may be disabled. The first data center may include a first data cluster and a first database. The first query dispatcher may be configured to dispatch queries to access data in the first data cluster and in a second data cluster at a second data center. The second data cluster may replicate data stored in the first data cluster. Metadata stored in the first database may be replicated to a second database in the second data center. The metadata may describe a state of the first data cluster. A second query dispatcher may be enabled at the second data center. The second query dispatcher may be configured to dispatch queries to access data in the second data cluster.
