Yes, it is nice to see everyone just pitch in and do it on this list.

Master/slave is not going away in our company. That cluster has zero downtime
in five years. I can’t say that about our Solr Cloud clusters.

, but I can’t remember what terms I preferred because
that was ten years ago. A master gives commands. That isn’t how Solr
masters work. It is closer to how an NRT or TLOG leader works, actually.
A Solr master just sits there and waits for other nodes to copy the index.

From that short description, you should not be running optimize at all.
Just stop doing it. It doesn’t make that big a difference.
It may take your indexes a few weeks to get back to a normal state after the
forced merges.

I’ve long thought that master/slave was not the right metaphor for a pull model
anyway.
We probably should not use “replica” since that already has a use in Solr Cloud.
Where is the discussion?

Elasticsearch does not have a good record on fault-tolerance. I haven’t checked
recently, but it was losing updates during leader elections for several years
worth of software releases.

Why have a cold backup and then switch? Every time I see that config, I wonder
why people don’t have both servers live behind a load balancer. How do you know
the cold server will work?

I wrote a Python demon that gets clusterstatus from the API, parses it, and
sends the counts of replicas in each state to InfluxDB. From there, we chart
and alert in Grafana. New Relic is good, but we need other kinds of metrics,
like the load balancer status from CloudWatch.

Are you sure they will wonder? I’d try it without that and see if the simpler
UI is easier to use. Simple almost always wins the A/B test.
You can use the highlighter to see if a field matched a term. Only use explain
if you need all the scores.
