Stefan Miklosovic commented on CASSANDRA-14351:
-----------------------------------------------
If we want to try that library, somebody would need to test how good of a match
it is for Cassandra. I briefly looked into the code of jsystemd and it is
questionable how well it would integrate.
Also, one problem I see is that library is developed by one person only, even
the project seems to be active.
The way I look at this is that it would be probably better if we introduce some
well-rounded library with a proper releases etc rather than doing this by hand.
On the other hand, if we do not plan to integrate with systemd more in the
future, the proposed solution might be just fine as well.

> When cassandra is started via systemd, it would be nice to support the
> [SD_NOTIFY|https://www.freedesktop.org/software/systemd/man/sd_notify.html]
> protocol so systemd know, when cassandra is ready (that can be use for
> dependencies or when you need to wait until cassandra startup is done).
> A very simple implementation could be done using the
> {code:java}
> systemd-notify --ready
> {code}
> command line tool (and ignore it if the tool is not there)
