@akimrx thanks for the new module!
Could you please revert renaming of the ignore.txt

[akimrx]

Hi! Yep, a little later

[Andersson007]

@akimrx thanks for the module!

Most the comments from the other PR is relevant here.
When it's ready for review, please put it explicitly and I'll ping the other folks to review.

Thanks.

Suggested change

you could also put the seealso section, with a link to related proxysql documentation. E.g. from postgresq_pg_hba module

114 seealso:
115 - name: PostgreSQL pg_hba.conf file reference
116   description: Complete reference of the PostgreSQL pg_hba.conf file documentation.
117   link: https://www.postgresql.org/docs/current/auth-pg-hba-conf.html

Just an idea, not necessary

Suggested change

	def update_server_config(self, cursor):
	def update_server_config(self, cursor):

can we pass it only once when initializing the object and use self.cursor everywhere?

If a specialist reviews, tests, and provides feedback that the c.proxysql users will get what they expect, we could merge the module

@markuman if you could take a look, it would be really great

Suggested change

	ProxySQL cluster hosts using the B(ProxySQL) admin interface.
	ProxySQL cluster hosts using the B(ProxySQL) admin interface.
	version_added: '1.2.0'

FYI: Whoever finishes this, i believe it would be fair if they put themselves in the authors: list

@markuman if you could take a look, it would be really great

I can take over. But I'd like to address #60, #61 and #62 first and release 1.2.0
So this will land in 1.3.0 if no one else will do it before :)

I will target #19 for the next release.
the benefits of using proxysql in cluster mode are - imo - marginal. Most of the benefits are already targeted by using an orchestration tool like ansible.
If someone has some time to complete this, feel free to adopt this pr.
