read that "Another optimization option is to start the index without any
replicas, and only later adding them". My index is relatively write-heavy,
so when I reindex, I shut down the replica (it's in master=false, data=true
mode) and bring it back later to receive updates in bulk.
Is there any way to make replica "invisible" for the updates, but online
for querying, without shutting it down? And afterwards enable it back so it
will receive updates? In this period it would serve stale data, which is ok.
