RelStorage also comes with a script named ``zodbpack`` that packs any
|
|
ZODB storage that allows concurrent connections (including RelStorage
|
|
and ZEO, but not including FileStorage). Use ``zodbpack`` in ``cron``
|
|
scripts. Pass the script the name of a configuration file that lists
|
|
the storages to pack, in ZConfig format. An example configuration file::
|
|
|
|
<relstorage>
|
|
pack-gc true
|
|
<mysql>
|
|
db zodb
|
|
</mysql>
|
|
</relstorage>
|
|

|
Options for ``zodbpack``
|
|
========================
|
|
|
|
``--days`` or ``-d``
|
|
Specifies how many days of historical data to keep. Defaults to 0,
|
|
meaning no history is kept. This is meaningful even for
|
|
history-free storages, since unreferenced objects are not removed
|
|
from the database until the specified number of days have passed.
|
|
|
|
``--prepack``
|
|
Instructs the storage to only run the pre-pack phase of the pack but not
|
|
actually delete anything. This is equivalent to specifying
|
|
``pack-prepack-only true`` in the storage options.
|
|
|
|
``--use-prepack-state``
|
|
Instructs the storage to only run the deletion (packing) phase, skipping
|
|
the pre-pack analysis phase. This is equivalent to specifying
|
|
``pack-skip-prepack true`` in the storage options.
