Hello Team,
We need to optimize the Postmeta tables. Since it has 2 GB. We tried to optimize the above tables. But it says like https://prnt.sc/8qE8ye8aNJqO. Please let me know the steps to resolve it. I have tried with WP optimizer Plugin and other plugins which are related to database optimizer. But still it says the same issue.
Thanks

Heya,
The error “The table does not support optimize” typically occurs when the database table engine is InnoDB, which does not directly support the
OPTIMIZE TABLE
command like MyISAM. Instead, you need to use alternative methods to optimize and clean up your wp_postmeta table.You can try using wp-cli to optimize all your DB tables. Run the following command to optimize all database tables, including
wp_postmeta
:If
wp_postmeta
uses the InnoDB engine, the optimization process may not reclaim space directly. Instead, use alternative methods (see Rebuild Table below).2. Clean Orphaned Post Meta
You can use WP-CLI commands to clean orphaned post meta. While WP-CLI doesn’t have a direct command for orphaned meta, you can use a plugin like WP-Sweep, which provides WP-CLI support.
Install WP-Sweep:
Then, run the sweep command to clean orphaned meta:
. Export and Analyze Large Tables
If the
wp_postmeta
table is too large, export it for offline analysis:You can analyze and clean the exported data locally using SQL tools or scripts
If you have WP-CLI installed, you can use the following command to remove orphaned metadata. These are entries that are not associated with any existing posts:
If manual methods seem too complex, or if you want additional optimization features, you can use some advanced database optimization plugins like:
postmeta
.This command deletes any postmeta entries that do not have a corresponding post.
You can also check the following articles:
Also you can run a script like the MySQL tunner to recommend optimised values for MySQL/MariaDB. There is a mini-tutorial which you can check here:
