Abstract
Techniques for managing a database cluster are disclosed. A database cluster stores a database in a distributed manner among multiple nodes. Applications query a node in the database cluster with a database language query to access data in the database. If the node determines it is in a pre-shutdown state, the node returns both query results and a status indicator. Based on receiving the indication of the pre-shutdown status, the application may continue to query the node to obtain data from the database for an ongoing task or operation. The application may then switch over to another node in the database cluster prior to the node changing to an inaccessible or shutdown state.
