Redis supports 6 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(s):

• if value is of type string -> GET <key>
• if value is of type hash -> HGET or HMGET or 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>
• if value is of type stream -> xread count <count> streams <key> <ID>. https://redis.io/commands/xread

Use the TYPE command to check the type of value a key is mapping to:

• type <key>
