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 |
