Enforce transaction log checkpoints.
CHECKPOINTA checkpoint is a point in the transaction log sequence at which all data files have been updated to reflect the information in the log. All data files will be refreshed to disk.
When this command is issued, the CHECKPOINT command forces the checkpoint to be executed immediately without waiting for a regular checkpoint scheduled by the system. CHECKPOINT is not suitable for use in regular operations.
If executed during recovery, the CHECKPOINT command forces the point to restart instead of writing to a new checkpoint.
Only superusers can call CHECKPOINT.
The CHECKPOINT command is a YMatrix database extension.
