No, it's up to the user to define his hash algorithm, as described here:
https://groups.google.com/d/msg/openresty-en/fTTXtVrMhhc/yXXF6CqmS2gJ
To make such logic reusable, I'd rather see a generic Lua library that
implements various common hash algorithms that are not only usable for
lua-resty-memcached, but lua-resty-redis, lua-resty-mysql, and any
other things. You're welcome to contribute a lua-resty-sharding
library, for example :)
