> Set derby.system.durability property when running tests to speed-up Derby
> operations by avoiding expensive I/O system calls. This change can have
> noticeable impact in CI environments and anywhere where file-system
> operations are slow.
> Local testing shows a performance gain of an order of magnitude when creating
> a new Derby database (times dropped from ~200ms to 20ms). In CI, these times
> are much bigger and reach the order of seconds.
> The property should not be used in production but it is OK for testing where
> we don't care about recovering from JVM crashes and errors.
> See: https://db.apache.org/derby/docs/10.8/ref/rrefproperdurability.html
