Data dependencies groups

It is a list of groups that each consists of a set of cookies, arguments, and database table dependencies.

Settings for each group:

  • Enable

    Enables/disables a specific group for easy customization, so as not to delete an element.

  • Group name

    Optional name to identify.

  • Cookies

    Pages’ requests having cookie names that begin with any of the specified strings will be treated as user-dependent and will be managed by the cache engine separately.

  • URI arguments

    Pages’ URLs having arguments that begin with any of the specified strings will be excluded from caching.

  • Tables

    List of user data-dependent tables that are used when user caching is active. When caching engine detects that user data has been changed according to specified tables, then it revalidates user session cached data to provide fresh content to the user. See the example below.

    Settings for each item:

    • Table name

      Database name of the table. Template %PREFIX% can be used that will be replaced by WordPress common database table name prefix.

    • Column name

      Table column name with user ID or field in the related table name.

    • Link ID column name in related table

      Table column name that pointed from an initial table column.

    • Column conditions in related table

      Filters rows in the related table by specified conditions.

Let’s look at the example by WooCommerce.

This plugin has its own post type to provide customer (user) orders storing. When the order is changed, we need to find out the related user ID and revalidate its cached data. So, orders are stored in the ‘wp_posts’ table and column ‘ID’ contains the order ID. Next, each order has information about the customer (user) that is stored in the post’s meta table named ‘wp_postmeta’ with ‘meta_key’ = ‘_customer_user’, ‘post_id’ contains order ID, and ‘meta_value’ contains needed user ID.

Finally, the depended table settings will be:

Table name %PREFIX%posts
Column name ID
Related table name %PREFIX%postmeta
Column name in related table meta_value
Link ID column name in related table post_id
Column conditions in related table meta_key = _customer_user
