Checkpoints in real-time tasks save the task's status to persistent storage, enabling restoration to the pre-crash state in the event of an unexpected failure. This topic outlines the steps to configure checkpoints for real-time tasks.
Procedure
For more information, see the real-time mode configuration entry to access the Real-time Mode configuration page.
On the configuration panel, in the Checkpoint Configuration section, set the Checkpoint Configuration details for the task's real-time mode.
ImportantWhen configuring the checkpoint here and filling in the checkpoint configuration in the Runtime Parameter, the following logic will take effect:,
If the checkpoint is not set here, the runtime parameter configuration will be applied.
If the checkpoint is set here, this configuration will override the runtime parameter.
Parameter
Description
System Checkpoint Interval
Specifies the periodic time interval for executing checkpoints, with a default of 180 seconds. This can be set in days, hours, minutes, or seconds. If left blank, the checkpoint feature will be disabled.
Minimum Time Interval Between Two System Checkpoints
The shortest allowable time interval between two system checkpoints, defaulting to 180 seconds. This can also be set in days, hours, minutes, or seconds.
ImportantEnsure a minimum time interval is maintained between two checkpoints if the maximum degree of parallelism for the checkpoint is set to 1.
