How to use memcached, it is enabled by default?

I want to use remote memcached server,
Where can I find a detailed description of the production deployment?


With v5, we use Redis for caching
You can setup a redis server and add the following to the sites/common_site_config.json

    "cache_redis_server": "redis://{your_cache_redis_server}:{redis_port}"

v5 no longer supported memcached?

No we are using redis hash tables for caching. Makes for much easier management.

Oh, thank you
