Looking to upgrade a cluster running 7.5 - should I go open search or elastic? Who will be the better maintainer? Reminds me of Mariadb and MySQL… either path was a fine choice IMO but hard to say in this case…

Elastic.co one thousand percent. I just finished a migration from AWS managed ES to Elastic.co. You literally only need to use both for a couple of hours to notice that AWS treats ES as an afterthought. I could name many things such as better security, interface and cold/warm storage configuration.

Not looking at either for manger service… just the open source projects- features etc…

Then you have no reason not to go with elastic unless you host on aws. From the drama described in the article it sounds like elastic will try to keep clients working only on its own fork while amazon will play catch up.

But ElasticSearch isn't open source, it's only source available.

https://github.com/elastic/elasticsearch

They changed the license but its still open source

That is not open source. That is source available. The SSPL is not an open source license.

It's a matter of interpretation really and more of the perspective of the reasons you require something to have its source code available. For example if you just need to be able to scrutinize the code for security purposes then it's good enough.

This looks pretty closed source to me: https://github.com/elastic/elasticsearch/blob/master/x-pack/...

That's what "source available" means. Open Source is a much stricter definition, which includes not discriminating what your user is going to do with the software.

From https://opensource.org/osd

> 6. No Discrimination Against Fields of Endeavor > The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.

For a lot of developers, there is no practical difference because they are not building a managed service around Elasticsearch (like Amazon is). They are using it for their own private, commercial purposes, whatever it may be.

That doesn't magically make it open source

OK, sure it's not open source then. Most people don't care.

Elasticsearch is a tool aimed at software developers. A number pretty close to 100% of its userbase should care about licenses.

Should and do are 2 completely different things.

I'll call bullshit to that: https://docs.aws.amazon.com/elasticsearch-service/latest/dev...

Does elastic have something like it?

Elastic has frozen tier, which is a step beyond what AWS is offering.

They have 4 steps if I recall clearly.

doesn't AWS Elasticsearch have the concept of UltraWarm? Isn't that like cold/warm?

Stick with elasticsearch of course, it's "the real thing", made by the people who have been working on the product for over 11 years. That's what I do. I wouldn't touch things related to Amazon with a 10 feet pole.

If you care about the open source philosophy, then definitely go OpenSearch.
