Salvatore Sanfilippo is stepping down as maintainer after eleven years, but will still sit on the Redis Labs advisory board–which is a good thing on many regards, since Redis now has a community (and a business) to support it and new governance, and Salvatore has too creative a mind to be tied down to a single thing.
Redis is one of my staple architecture components (and many people have no clue as to what it can really do besides “caching”), and is of the best pieces of tech I’ve ever used, so I’m really thankful for his work.
