This is what I'm talking about wrt bitching and moaning, in summary you tried to use ES but you didn't rtfm or didn't know about jvm tuning or didn't scale test and found out the weekend is a bad time to come up to speed on those, you had a bad time several times, plus you slashdotted yourself with monitoring; then you did a custom implementation for your vertical use case which didn't have the rtfm problem because you wrote it, but also only satisfied your case as opposed to the wide applicability of ES. Ultimately cool story bro because ES is freely available for anyone to use (many people do this) and modify (some people do this too) and your alternative is unknown.

What are the fundamental flaws of ES and what alternatives avoid those flaws, or how do you propose ES could address those flaws?

For example:

- "Algolia is so much better because it is a managed service." (hey whatsup ycombi)

- "Solr is also lucene but necessarily requires significant customization to the workload which avoids the common ES problem of it appearing to work so well out of the box that people neglect the details until it becomes an incident."

- "ES fundamental flaw is that zen disco mcast nonsense, people please stop being clever using mcast it never works in practice because igmp snoop". (hey whatsup we out here using ES since a while now)
