You mention using
$redis_server = array(
'host' => '127.0.0.1',
'port' => 6379,
'auth' => '12345',
'database' => 0, // Optionally use a specific numeric Redis database. Default is 0.
);
when not on Pantheon but it's just as easy to use/setup the Pantheon environment variables when using a VPS. In the code you aren't allowing for the selection of a database, with a fallback default, to make this usable without that custom code. I can't use that custom code when using a Composer-based managed WordPress instance.
So as I was going back to check any other cases where the $redis_server
array was being used I discovered that there is a filter that could be used in this case wp_redis_prepare_client_connection_callback
This would be in order to support multiple servers connecting to the same Redis instance. Using just the
WP_CACHE_KEY_SALT
is not enough when you end up calling thewp_flush_cache()
method as it will remove everything in the DB instance not just those items with the specifiedWP_CACHE_KEY_SALT
.
