Sorry, I am not sure why you brought up a single instance. If you run on a single instance, you lose half of the benefits of ES which is trying to be highly available.
If we have an index which does not need any backups, single instance is fine, but for most people single instance is not an option. Furthermore, if one is already struggling with 3-4 nodes, how helpful is single instance?
- threeseed 9y agoI brought up single instance since you suggested using a SQL database most of which don't support a distributed deployment in the same way ElasticSearch does. My point was merely that ElasticSearch scales from very small use cases to very large ones. You don't have to setup a cluster. And that using your SQL database isn't going to be significantly easier to manage.
