Largely my take as well... I will say, I'm not a fan of using the DB Engine to self-injest or export data... I do prefer newline delimited json for import/export as it tends to be easier than CSV usually is. The variations in SQL dialects/engines are pretty broad... and in some cases (mysql, ugh) straight ANSI SQL syntax may or may not work as expected. Not to mention more esoteric data like JSON or XML data columns. One other niggle, don't do data analytics against your live database servicing your applications... use a read mirror or replica node... The types of queries data analysts tend to run are often less than ideal in terms of performance characteristics. Developers can create bad enough queries as it is, let alone a DA query locking a key table for many seconds.
