Enum Constant Details

REGULAR

public static final TaskQueue.TaskPriority REGULAR

The default priority for a task. No special treatment.

ELEVATED

public static final TaskQueue.TaskPriority ELEVATED

Elevated priority for a task. When present in the queue, elevated requests are favored for execution over regular priority tasks, using the configured priority ratio to prevent "starving" the regular priority tasks.

CRITICAL

public static final TaskQueue.TaskPriority CRITICAL

Critical priority for a task. When present in the queue, always executed ahead of elevated or regular priority tasks. No limit or ratio to prevent "starving" lower priority tasks.
