After ClickHouse became systemd aware (#43400), it waits not more then TimeoutStartSec (1m30sec by default), while before it simply ensures that the process is there. And likely 1m30sec can be not enough for some cluster, and this will lead to endless restarts. At first I've increased it to 10min, but there was a comment about that this is not enough, and I agree with this. But I'm not sure that using "inifinity" is a good option, but I cannot think of any downsides of this. Signed-off-by: Azat Khuzhin <a.khuzhin@semrush.com>
