You can put a JSONB column in any of your tables to handle the part of your data that is schemaless, and you can still index the data in that JSONB column.&lt;p&gt;There are a very few applications that need distributed scalability beyond what Oracle or PostgreSQL can provide, and those ones need NoSQL. They also need highly skilled competent developers who are capable of reimplementing some needed functionality of RDBMSes at scale.</text><parent_chain><item><author>epmaybe</author><text>Why wouldn&amp;#x27;t you always use something that is tried-and-true?

The appeal of &amp;quot;no schema&amp;quot; is most likely what gets them as it seems easier than SQL. Simple things at first seem daunting like: constraints, joins, and indexes. What they fail to see is that doing these database level things in the application layer becomes the final level hell and you get to live it.&lt;p&gt;People also undervalue their data and it&amp;#x27;s integrity.&lt;p&gt;I personally do not like mongo and see zero reason for it except perhaps in some very niche use cases and even then, I&amp;#x27;d still choose another document store over it.</text><parent_chain><item><author>epmaybe</author><text>Why wouldn&amp;#x27;t you always use something that is tried-and-true?
