We now provide reactive SCAN support for keys, hashes, sets, and sorted sets. Scanning uses a cursor-based Flux and takes subscriber demand into account to issue the according scan commands once a batch of keys/values/entries was emitted. Specifying a SCAN limit controls the batch (page) size and can be used to optimize the number of roundtrips between the application and Redis.
