CLIENT CACHING YES|NO
This command controls the tracking of the keys in the next command executed by the connection, when tracking is enabled in
OPTOUT mode. Please check the client side caching documentation for background information.
When tracking is enabled Redis, using the CLIENT TRACKING command, it is possible to specify the
OPTOUT options, so that keys in read only commands are not automatically remembered by the server to be invalidated later. When we are in
OPTIN mode, we can enable the tracking of the keys in the next command by calling
CLIENT CACHING yes immediately before it. Similarly when we are in
OPTOUT mode, and keys are normally tracked, we can avoid the keys in the next command to be tracked using
CLIENT CACHING no.
Basically the command sets a state in the connection, that is valid only for the next command execution, that will modify the behavior of client tracking.
Simple string reply:
OK or an error if the argument is not yes or no.
