Hello, a newbie here. I am trying to understand if the yellow cluster status can affect performance or not.
I am storing logs in ElasticSearch with Logstash and I really don't care about high availability. I mean, if the cluster dies and I lost all logs it's not a big deal. As long as this does not happen too frequently hehe. It's on AWS by the way.
So the question is, if I only have one data node (
m4.large.elasticsearch) so the cluster status is always yellow, should I expect ElasticSearch to perform slower?
I have stored around 30GB of data, 10 million documents (and growing), and kibana is taking a lot of time to show just the discover page for the last 24h. The dashboard timeouts, cause every panel (even the most simple ones) takes seconds to query.
Copying the queries to postman shows similar results: requests take seconds. Sometimes, if I send the same request again and again, it takes a few milliseconds. But most of the time it is over 1 or 2 seconds.
TLDR; Is cluster status=yellow a problem in terms of search/index performance?
