I understand the optimum RAM:disk ratio is 1:24. Based on my own testing, I've used 1GB of RAM to support up to 77GB of data in Elastic's (based on Kibana's "store.size"). But that's a bad test since it crashed at that point.
Based on my previous talks with Elastic staff IRL, my previous understanding was that if there's less RAM, Elastic would simply be slower, and that was a tradeoff I was willing to make. But it seems if there is not enough RAM then Elastic just crashes instead.
So my questions:
- Is there a maximum ratio that Elastic would say is absolutely wrong? e.g. 1:50 is "max".
- Is there some setting that would help me improve this ratio, or prevent Elastic from crashing?
