servers
Change the replica first, then the master. Each will index
independently.

I tried to search for the answer, but couldn't find it, I would
appreciate if any of you could direct me to the correct chunk of
documentation to find this out:
We have two node ML7 setup where one of the nodes is master and other
slave using database replication matched by the database name. (This
is NOT flexible replication)
We execute queries to both hosts 24/7 but obviously write only to the
primary one.
We often need to add new indexes to the system and the (multi part)
question is:
1. Does ML replicate the index definitions between hosts?
2. Does ML replicate the indexes themselves between the hosts?
3. What's the correct procedure to add a new index in this setup?
We currently add the indexes by hand, starting from the slave. We
noticed that the slave does not initiate automatic reindexing, even
though we have "reindexer enable" set to true and figured it's better
to add the new index to slave first so that it will be there when the
primary starts reindexing.
So, is it required at all to add the indexes first to slave, or will
ML take care of the configuration changes via the replication also or
does that include only data?
