📝 Questions & Answers:

Q1: What is `XREADGROUP`?
A1: `XREADGROUP` reads messages for a consumer group and claims pending entries for processing. Example: Like a group member fetching new assignments from a shared to-do list and marking them as in-progress.

Q2: What are Redis Streams?
A2: Streams are an append-only log data type supporting consumer groups and message persistence for message queues and event sourcing. Example: Like an ordered activity log that multiple consumers can read from and coordinate which entries they processed.

Q3: What are common Redis security practices?
A3: Use ACLs, strong authentication, TLS, network segmentation, and avoid exposing Redis directly to the internet. Example: Like putting the whiteboard in a locked room, limiting who can enter, and using sealed envelopes for sensitive notes.
