Fortunately, we have options to store these transients in the memory using one of the backends mentioned above. Among these, Redis has become stable and is production-ready. There are two WP plugins available that use Redis as WP Object Cache. First one is Eric Mann’s plugin. The second plugin is by Till Krüss who forked the former and made it better.
