Does it really matter what values we set in refresh_interval for a read-only index? I'm re-indexing a huge index that contains legacy data and is never updated i.e read-only (RO).
Before re-indexing, in order to boost performance I'm setting
"refresh_interval": -1. Once re-indexing is over, it is necessary for me to reset the refresh_interval back to say
I'm wondering if not re-setting back to
60s will make any difference since this index isn't going to get any data post re-indexing.
