So You Think You Know Redis!
summary
Game‑show pacing masks concrete demos and gotchas: redis-cli -x stores binary blobs (Elvis.jpeg) and returns escaped bytes, strings are blobs, bitfield commands extract arbitrary bit-width integers (u7 at pos 1 returns 72), LPOP/LPUSH ordering surprises, sorted‑set ZINTER/ZUNION aggregates scores by SUM by default, modules add commands and types and cannot be unloaded if their types persist, maxmemory + eviction policies (volatile‑LRU) and save 1 1 semantics matter for durability. modules add types, bitfield extraction.
