CHECKPOINT — force a write-ahead log checkpoint
CHECKPOINT
A checkpoint is a point in the write-ahead log sequence at which all data files have been updated to reflect the information in the log. All data files will be flushed to disk. Refer to Section 27.4 for more details about what happens during a checkpoint.
The CHECKPOINT command forces an immediate
checkpoint when the command is issued, without waiting for a
regular checkpoint scheduled by the system (controlled by the settings in
Section 17.5.2).
CHECKPOINT is not intended for use during normal
operation.
If executed during recovery, the CHECKPOINT command
will force a restartpoint (see Section 27.4)
rather than writing a new checkpoint.
Only superusers can call CHECKPOINT.
The CHECKPOINT command is a
LightDB language extension.
