ZDIFF
112+
Redis 6.2 introduced the ZDIFF
113+
For previous versions use:
114+
ZADD all 1 one 2 two 3 three
115+
SADD disabled two # this is the created intersection set

TRANSACTION
119+
MULTI # to start a transaction: this will queue and batch commands later
120+
EXEC # execute all queued commands atomically/TRANSACTION
121+
DISCARD # Abort a transaction

OPTIMISTIC LOCKING
123+
MULTI
124+
watch event:signups # exec will abort a transaction (nil is returned by EXEC) if a watched key before MULTI was modified by another client
125+
unwatch # if exec succeeds all keys are unwatched automitically
