How to set the TTL of "operations:${responseId}"?

[NMZ0429]

I am using useResponseCache to store responses in Redis. My question is that how to set the TTL of the cache with the key "operations:${responseId}" which are made along with response caches. I have set TTL of responses to 5 min but that of "operations:" is still infinite. What setting should I add?

As I checked the source code, I see that the key's name could be change from "operations:" but can not find any TTL related code.

Edit

I just noticed that the cache keys "operation" are not generated for some queries. I haven't figured out which query makes the cache.
