Say, I'm using day-wise indices with 5 shards and 1 replica. In kibana dashboards, when I fire a dashboard for last 7-days which in turn fires a number of underlying visualisations in that dashboard, the queries - do they hit
ALL the day-wise indices (and thereby shards) or they only hit the
day-wise indices (and shards) that fall in the 7-day time range?
Here are the screenshots of the elasticsearch visualisation request and response and I believe it only hits
the indices (and shards) that fall in the 7-day time range and not ALL indices. My retention is currently 150 days and thus there would be 150 indices.
total field tells me that 40 shards are hit which looks to be correct since for last 7 days, it would hit 8 days * 5 shards = 40.
Can someone please confirm that the kibana dashboard/visulizations queries ONLY hits the indices (and shards) that fall within the time range specified in Kibana or it hits ALL indices?
