# Redis supports 5 data types. You need to know what type of value that a key maps to, as for each data type, the command to retrieve it is different. Here are the commands to retrieve key value:
if value is of type string -> GET <key>
if value is of type hash -> HGETALL <key>
if value is of type lists -> lrange <key> <start> <end>
if value is of type sets -> smembers <key>
if value is of type sorted sets -> ZRANGEBYSCORE <key> <min> <max>
# Use the TYPE command to check the type of value a key is mapping to:
type <key>

# Delete all keys matching users*
redis-cli --scan --pattern users:* | xargs redis-cli del
