REDIS GET

[Santos Das]

Hi,

I am storing like this,

Key1 --> Val1

Key2 --> Val2

Actually, Key2 is nothing but Val1. My interest is given Key1, get Val2. I am doing this in two separate GETs. Is there a way where I can do this using a single GET.

Thanks, Santos

you could write a Lua script that does the indirection at the server, and use EVAL / EVALSHA ?

@Marc - I love you, you know that, but that's not the answer. You should explicitly pass any keys that you touch in the script as arguments (the KEYS table). Do not hardcode/generate/read them.

@Santos - no, there isn't. The real question is, however, why are you doing this key "dereferencing" and whether it is actually needed.

Cheers,

Itamar

hmm, yes, good point on the key touch. caveat: it should be OK if the same cluster shard key magic notation applies to both, but indeed: in the general case, it would be bad practice. Thanks for keeping me honest :)

Cluster hash tags are beyond magical - they're the silver bullet and much more, agreed.

Thanks for keeping us in shape :)
