Locking that Occurs when BACKUP DATABASE is Run
If BACKUP DATABASE
is run, the following applies before the backup starts:
-
The aggregator briefly blocks new queries from running across the cluster.
-
If there is a long-running write query executing,
BACKUP DATABASE
waits for the query to complete.
Once BACKUP DATABASE
is running, queries against the cluster can proceed normally.
