Database Optimization Suggestions

Also, I've attached the top four tables that occupied the maximum space.

In attached, you will see that
wp_6hp6nqm250_postmeta – 9 GB
this is the table used in maximum queries in both the front end and backend

Please provide suggestions for optimizations for above db table and db
Correct above

### **1. Optimize the `wp_postmeta` Table**
Since `wp_postmeta` tends to grow large in WooCommerce and WordPress setups due to excessive metadata storage, you can apply the following optimizations:

#### **a. Clean Up Unused Metadata**
– Run the following SQL query to check for orphaned metadata (metadata without a corresponding post):

SELECT meta_id 
  FROM wp_6hp6nqm250_postmeta pm 
  LEFT JOIN wp_6hp6nqm250_posts p 
  ON pm.post_id = p.ID 
  WHERE p.ID IS NULL;

– Delete orphaned metadata:

DELETE pm 
  FROM wp_6hp6nqm250_postmeta pm 
  LEFT JOIN wp_6hp6nqm250_posts p 
  ON pm.post_id = p.ID 
  WHERE p.ID IS NULL;

#### **b. Identify and Remove Unused Meta Keys**
– Check the most commonly used meta keys:
“`sql
SELECT meta_key, COUNT(*) as count
