Using GUID (or similar) has performance penalty in Redis?

redis

Solution

Redis use a hash strategy to store all keys, every key is stored using a hash function. All Redis db peformance about keys fall into this function - or something related.

Original key is also stored to figure out future colisions between diferent keys, and yes big keys could be impact at memory handle and all of related fields : memory fragmentation, cache hits/misses, etc ...

Problem

Does using a GUID or ulong key impact Redis DB performance? Similar: Does name length impact performance in Redis?
