twemproxy is not the best piece of software when it comes to maintenance of code quality. But it works reliable. We are still using twemproxy and we are maintaining our own fork of it. This fork often has changes from us, like bugfixes or introducing new redis commands that are not supported yet.

Every bug we fix we apply this as a PR. A few PRs from the repository we have cherry-picked internally and deployed. But we have also a few issues with it like this one here: https://github.com/twitter/twemproxy/issues/442 or live reconfiguration would be a nice feature. Think about it if you really need this, because it is not only fun. A few pain points:

* Deployments of new configs and restarting twemproxy on your server farm

* New redis version with new commands? Extend twemproxy for those command support

I don't now any _real_ alternative to it, right now. I know from https://github.com/Netflix/dynomite which is a twemproxy fork. When we had only memcached and no redis (we are using both with twemproxy), then we would try https://github.com/facebook/mcrouter from facebook. But it is specialized on memcached.

If you come up with an alternative, please let me know.
