DBQL tables occupy permanent space in database DBC. This means that once a row has been sent to an AMP, its insertion into a DBQL log is safeguarded through the transaction and recovery journaling process.

In addition, the data in every DBQL table is protected with FALLBACK. This means that the data is always available unless two or more AMPs in the same clique fail simultaneously.
