How to copy data from hash to sorted set

[Ankit Gupta]

Hi Experts,

We are moving our metadata from hash to sorted set to support expiry of fields in hash.

We wanted to understand if there's any easy way/command to copy data between these 2 different data-structures. 

Thanks,

Ankit

We are using redis version 5.0.5

Redis doesn't have a built-in conversion command from a hash to a sorted set, so you'll have to write a script to do that.  I imagine you'll have to change your client code to handle the different commands for reading/writing a sorted set rather than a hash, so you'll already be coordinating an explicit change and not trying to change the hashes while clients are actively using them.  So a script to convert each hash -> sorted-set ought to be fairly simple.
