Abstract:
1. A method for recovering from a failure of a processing node, the method comprising: storing, prior to failure of a first processing node of a plurality of interconnected processing nodes, a database portion of the first processing node on a second processing node of the plurality of processing nodes; replacing the first processing node with a third processing node of the plurality of processing nodes when the first processing node fails; copying the database portion of the first processing node from the second processing node to the third processing node between database operations performed by the second processing node and the third processing node; performing, by the third processing node, database operations using the database portion of the first processing node stored on the second processing node during the copying of the database portion of the first processing node from the second processing node to the third processing node; and performing, by the third processing node, database operations using the database portion of the first processing node stored at the third processing node when the copying of the database portion from the second processing node to the third processing node is completed.
