Please check the
client side caching documentation for
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
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.
