Collects the number of active checkpoint file pairs in Memory-Optimized Data Filegroup.
The rule collects the number of active checkpoint file pairs in Memory-Optimized Data Filegroup.
Active CFPs contain the inserted/deleted rows from previous closed checkpoints. They contain the contents of the tables that area read into memory before applying the active part of the transaction log at the database restart. We expect that size of these checkpoint files to be approximately 2x of the Memory-Optimized data size of memory-optimized tables, assuming the merge operation is keeping up with the transactional workload.
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 |
