[Koha-devel] RabbitMQ / bug 26742: in production message broker on a specific server ?

[Zeno Tajoli]

Hi Devid and all,

I confirm that I will use Koha Debian packages (probably I will use 
Debian 10 with ES 6.x and PSGI/Plack).

As you say, it is not a drama to use  RabbitMQ. as local service.

That you for the info.

Bye
Zeno Tajoli
