Subject Re: Replication downtime?? - master slave

Replication is basically a background file transfer, your slave shouldn't

But what your slave will notice is two things:
1> after replication if your first few queries are slow, you need to
     autowarm your caches.
2> you will see some memory footprint increase while autowarming
     is going on

But by and large, your slave won't notice the replication itself and the
other stuff is configurable via autowarming parameters in your various
caches and newSearcher/firstSearcher
