Abstract

In one respect, there is provided a distributed database system that includes a first local scheduler node and a second local scheduler node. The first local scheduler node can be configured to coordinate a performance of a first task and a second task by a first worker node associated with the first local scheduler node. The second local scheduler node can be configured to respond to a defect at the first local scheduler node by at least: collecting, from the first worker node, a log indicating one or more tasks completed by the first worker node prior to the defect at the first local scheduler node; determining, based at least on the log, that the first worker node has completed the first task but not the second task; and coordinating a performance of the second task by the first worker node. Related methods and articles of manufacture are also provided.
