Isn't that exactly what they're trying to demonstrate though? That all this arcana you have to invoke to get a stable ES cluster barely breaks a sweat on Redisearch?

The specific test deployment was multitenant anyway-- you can't account or optimize for what tenants are going to index.

I'm not familiar with RediSearch, but I'm just trying to point out that you can't misconfigure ES and then benchmark against a misconfigured cluster. This is comparing apples to oranges. Not to mention I'm not sure of the feature difference between the 2 search engines, but I'd bet ES is much more feature rich, thus its use cases are vastly different. If you are just comparing text search, sure, maybe redis is faster. But at that point, so is a simple sql database, when compared to a misconfigured ES cluster.

I'm not familiar with Redisearch either but I agree, there's definitely a bent to this in that they made something that isn't ES, then compare it to ES via a a benchmark that shows how poorly ES performs at...being something other than ES.

The impression I got was that they were trying to demonstrate for two specific workloads, how much more a single node of RS can do than a single node of ES, and that we should extrapolate the savings and performance if scaled out from there.

A properly deployed ES cluster versus a single RS node isn't a fair comparison either. It's a strained comparison in any case.

"The specific test deployment was multitenant anyway-- you can't account or optimize for what tenants are going to index."

So in other words:

"If your specific use case is supporting 50,000 customers each having around 500 documents and only needing basic text search queries and relevance is not a major concern, RedisLabs Search might give you better performance than ElasticSearch!"

(This is assuming there isn't a different way to configure ElasticSearch to work for this scenario, that gives similar performance.)

I wouldn't call that "arcana", that's just ES and lucene basics
