For what it&#x27;s worth, Korma isn&#x27;t an ORM such as what you would use in Python. It&#x27;s a relatively thin wrapper around SQL queries. I don&#x27;t know whether they found that to be plus or not, but it would put it in a slightly different category than the Python ORM options.<p>I&#x27;m also betting that the startup time of the JVM wasn&#x27;t terribly important in their scenario.
