Example 1 with ADTaskType

use of org.opensearch.ad.model.ADTaskType in project anomaly-detection by opensearch-project.

the class ADTaskManager method getAndExecuteOnLatestADTasks.

/**

 * If resetTaskState is true, will collect latest task's profile data from all data nodes. If no data
 * node running the latest task, will reset the task state as STOPPED; otherwise, check if there is
 * any stale running entities(entity exists in coordinating node cache but no task running on worker
 * node) and clean up.
 * [Important!] Make sure listener returns in function
