All of A, C, and I only make sense defined relative to a particular transaction vocabulary. Redis is perfectly ACID, as long as your transactions are those supported by Redis's commands. Conversely, plenty of DBs with programmable transactions (e.g. SQL) are considered work-a-day "ACID" enough, despite some massive gaps in their transactional model (no DDL in transactions, no nested transactions, atomic only when below a certain size, etc.)
