Abstract
Various embodiments of systems and methods for faster restart of task nodes using periodic checkpointing for data sources are described. A task node obtains data from data sources in order to perform one or more tasks. The task node checkpoints data source progress points for each of its data sources, whether active or inactive, into a common checkpoint data structure at least once every time interval. Multiple task nodes checkpoint their data source progress points into the same common checkpoint data structure. After restart, the task node determines where to resume obtaining data from its data sources by determining a limited portion of the common checkpoint data structure based on the time interval, analyzing only the limited portion of the common checkpoint data structure, retrieving the data source progress points for each of its data sources, and resuming obtaining data from the data sources to perform tasks.
