+This option may be used for database connections which have "writers" assigned
+(see above). If specified, it causes a writer to put several updates into a
+single transaction. This transaction will last for the specified amount of
+time. By default, each update will be executed in a separate transaction. Each
+transaction generates a fair amount of overhead which can, thus, be reduced by
+activating this option. The draw-back is, that data covering the specified
+amount of time will be lost, for example, if a single statement within the
+transaction fails or if the database server crashes.
