      void populate(com.datastax.oss.driver.api.core.CqlSession session) throws ScriptException
      Populate, initialize, or clean up the database using the provided CqlSession connection.

      Concrete implementations may throw a RuntimeException if an error is encountered but are strongly encouraged to throw a specific ScriptException instead. For example, Spring's ResourceKeyspacePopulator wrap all exceptions in ScriptExceptions.

      Parameters:
      session - the CQL CqlSession to use to populate the keyspace; already configured and ready to use; never null
      Throws:
      ScriptException - in all other error cases
