I have been having an issue with Redis & Woocommerce since the summer but can’t figure out the solution. Could you help me understand it?
This is what they send me via mail:
Thanks for getting back to us on this. From what I can see, the product attribute lookup table is still constantly regenerating. At times, the database entries and the number of products listed in the regeneration button (that is the (120) shown in your screenshot) do not match unless the Redis Object Cache is cleared.
It appears that you may need to add options to your Redis ignored groups. I would do this only as a test.
Please enable WP_DEBUG and WP_DEBUG_LOG at the start of the test. (https://wordpress.org/documentation/article/debugging-in-wordpress/#example-wp-config-php-for-debugging)
Redis object cache allows WordPress users to exclude certain groups from being cached, which would cause the keys of the ignored groups never to be stored in Redis. It can be done by using the WP_REDIS_IGNORED_GROUPS WordPress constant in the wp-config.php file.
define( 'WP_REDIS_IGNORED_GROUPS', [ 'options']);
This does not address the issue of the regeneration being generated on every page load, but it may give us an indication of why the process is not completing. Once we have run the test and have some results, please re-enable options, as this is a key component to Redis caching.
Redis Object Cache answer:
WooCommerce works well with WordPress’ persistent object cache API, however WPML in one of the only few plugins that does not. We currently recommend not using WPML because of that.
However you can ignore certain cache groups like options, which might make WPML work, but all WordPress options won’t be cached anymore.
