| ================================ |
| |
| The ``commitlog-archiving.properties`` configuration file can optionally set commands that are executed when archiving or restoring a commitlog segment. |
| |
| =========================== |
| Options |
| =========================== |
| |
| ``archive_command=<command>`` |
| ------ |
| One command can be inserted with %path and %name arguments. %path is the fully qualified path of the commitlog segment to archive. %name is the filename of the commitlog. STDOUT, STDIN, or multiple commands cannot be executed. If multiple commands are required, add a pointer to a script in this option. |
| |
| **Example:** archive_command=/bin/ln %path /backup/%name |
| |
| **Default value:** blank |
| |
| ``restore_command=<command>`` |
| ------ |
| One command can be inserted with %from and %to arguments. %from is the fully qualified path to an archived commitlog segment using the specified restore directories. %to defines the directory to the live commitlog location. |
| |
| **Example:** restore_command=/bin/cp -f %from %to |
| |
| **Default value:** blank |
| |
| ``restore_directories=<directory>`` |
| ------ |

| **Default value:** blank |
| |
| ``restore_point_in_time=<timestamp>`` |
| ------ |
| Restore mutations created up to and including this timestamp in GMT in the format ``yyyy:MM:dd HH:mm:ss``. Recovery will continue through the segment when the first client-supplied timestamp greater than this time is encountered, but only mutations less than or equal to this timestamp will be applied. |
| |
| **Example:** 2020:04:31 20:43:12 |
| |
| **Default value:** blank |
| |
| ``precision=<timestamp_precision>`` |
| ------ |
| Precision of the timestamp used in the inserts. Choice is generally MILLISECONDS or MICROSECONDS |
