Meta Optimizer

This plugin optimizes WordPress meta data storage by saving all meta data for each post, comment, user, or term in a single row with separate columns for each meta key. This reduces the number of rows and improves the query performance and data export. The plugin works seamlessly with WordPress core functions and hooks, and supports any plugins that use them. Some of the features of this plugin are:

• Custom database tables for each type of meta data (post, comment, user, term)
• Compatibility with WordPress queries
• Faster queries and easy data export
• Data migration from default WordPress meta tables
• Option to exclude specific fields from core meta tables
• Support for popular plugins and themes such as Advanced Custom Fields, Meta Box, CMB2, and more.

How to plugin works

Instead of storing each post, comment, user, term meta in a separate row, this plugin lets you store them all in one row, with each meta key as a column.

Plugin Hooks

Change import items number

add_filter( 'wpmetaoptimizer/import_items_number', function ( $importItemsNumber ) {
    // return numeric value
    return $importItemsNumber + 20;
} );

 

Attention

If you use reserved column keys such as post_id for post meta, the plugin adds a suffix to the meta key. It creates a column based on the renamed key. As an example, if you save meta with key post_id, then plugin adds _wpmork suffix and creates column post_id_wpmork. In response to a query (WP_Query), the plugin automatically changes the meta key if necessary.

 

Update post meta example

update_post_meta(1, 'post_id', 222);

The meta key has been changed to:

update_post_meta(1, 'post_id_wpmork', 222);

 

Example Query:

$query = new WP_Query(array(
    'orderby' => array(
        'post_id' => 'DESC'
    ),
    'meta_query' => array(
        'post_id' => array(
            'key' => 'post_id',
            'compare' => 'EXISTS',
            'type' => 'NUMERIC'
        )
    )
));

Plugin changed a query to this:

$query = new WP_Query(array(
    'orderby' => array(
        'post_id_wpmork' => 'DESC'
    ),
    'meta_query' => array(
        'post_id_wpmork' => array(
            'key' => 'post_id_wpmork',
            'compare' => 'EXISTS',
            'type' => 'NUMERIC'
        )
    )
));
