Posting Etiquette

  1. Ask the main part of your question in the title. This should be concise but informative.

  2. Provide everything up front. Don't make people fish for more details in the comments. Provide background information and examples.

  3. Be present for follow up questions. Don't ask for help and run away. Stick around to answer questions and provide more details.

  4. Ask about the problem you're trying to solve. Don't focus too much on debugging your exact solution, as you may be going down the wrong path. Include as much information as you can about what you ultimately are trying to achieve. See more on this here: https://xyproblem.info/

What is NoSQL good for? (programming.dev)

I’m versed enough in SQL and RDBMS that I can put things in the third normal form with relative ease. But the meta seems to be NoSQL. Backends often don’t even provide a SQL interface.

So, as far as I know, NoSQL is essentially a collection of files, usually JSON, paired with some querying capacity.

  1. What problem is it trying to solve?
  2. What advantages over traditional RDBMS?
  3. Where are its weaknesses?
  4. Can I make queries with complex WHERE clauses?

Yup. And this right here is where I dismiss people that generally say you only need one or the other. Each has a specific advantage and use case and you’ll have the best performance when you choose the “right tool for the job” and don’t just attempt to shoehorn everything into a single solution

Hold a sec. Rolling your own RDBMS out of a NoSQL database is insane. But is the opposite feasible? Wouldn't it be a simple table with two columns: a key and a JSON blob?

Could you do it? Yes, but it’s not something that it’s optimized to do. NoSQL engines are designed to deal with key value pairs much better than an RDBMS. Again, best tool for the job.

Got it, thanks.
