Vacuum
======

Vacuuming is available for Spine Databases in the SQLite format. Basically it tries to free up some unnecessary
memory from the ``.sqlite`` file. If you have very large databases, it might be beneficial to vacuum it once in
a while. More detailed explanation on what vacuuming does to the SQLite database can be found
`here <https://www.sqlite.org/lang_vacuum.html>`_.

To vacuum a database, either press the |broom| Vacuum -button from the Data Store **Properties** panel, or
straight from the Spine Database Editors from **Edit->Vacuum** in the **Menu bar**.

After the vacuum is finished, a message informing the amount of bytes freed from the database is shown.
