HSQLDB for CrowdID

The default version of CrowdID uses an embedded HSQLDB database.

Also see http://hsqldb.sourceforge.net/doc/guide/ch01.html#N101C2 .

HSQLDB periodically must update its files to represent changes made in the database. In doing so, it must delete the current crowddb.data file on the filesystem (beneath the /database folder) and replace it with a new one.

If an administrator issues a shutdown on CrowdID in this period, data can be lost, and typically all configuration data for your CrowdID server will be lost.
