Redis

The command TOUCH is written in the dock Changes the time of the last access to the key.

What is it for? Can you give examples plz

Answer 1

radish considers "easy" to write: how much time has passed since the last access (read or write).
the touch command resets this counter to zero.
how to use it depends only on your imagination.
for example, I'm deleting some post types that haven't been accessed for more than a certain amount of time. using touch allows me to "update" such entries without accessing them directly.
