Is there a command to explicitly force a reindex of ALL indices?

  1. Not in high load 24/7, load seems to be internally manifesting right now and the reason it is choking and not because of external load. Though the individual requests are large, there is not a ton of them. Could be the large size of the requested data choking the alphas?
  2. I only mention live loading on v21.12 because we were running out of memory and why we upgraded, but seems I found parameter tweaks that are helping this
  3. I am not totally clear on the difference between replicas and groups, but we only have one group and looks like 3 replicas?
