Tuning performance of START AFTER COMMIT statements
Background tasks can be controlled with SSC-API and admin commands (see solidDB® Shared Memory Access and Linked Library Access User Guide for details). The task type SSC_TASK_BACKGROUND is used for the tasks that execute statements started with START AFTER COMMIT. You can give this task type higher priority or lower priority, or you may suspend this task type.
Note that there may be more than one of these tasks, but you cannot control them individually. In other words, if you call SSCSuspendTaskClass for SSC_TASK_BACKGROUND, it will suspend all the background tasks.
