Collects the number of Checkpoint Files Waiting For Log Truncation in Memory-Optimized Data Filegroup.
The rule collects the number of checkpoint file pairs waiting for log truncation in Memory-Optimized Data Filegroup.
Once the merge has been installed and the MERGE TARGET CFP is part of durable checkpoint, the merge source checkpoint files transition into this state. Files in this state are needed for operational correctness of the database with memory-optimized table. For example, to recover from a durable checkpoint to go back in time.
Name | Description | Default Value |
Enabled | Enables or disables the workflow. | Yes |
Interval (seconds) | The recurring interval of time in seconds in which to run the workflow. | 900 |
Script Delay (milliseconds) | This parameter sets the delay between consecutive T-SQL queries executed by the workflow. This may help to reduce the footprint generated by the workflow in case of large number of target objects. Please advise with Microsoft Support before changing this parameter. | 0 |
Synchronization Time | The synchronization time specified by using a 24-hour format. May be omitted. |
|
Timeout (seconds) | Specifies the time the workflow is allowed to run before being closed and marked as failed. | 300 |
