Remove posts we don’t need
WordPress saves all post types (posts, pages, tradition post types) into a
wp_posts list and a associated metadata to
If we empty a trash in a “Posts” and “Pages” panels in your WordPress admin we already get absolved of a lot of nonessential data. If we have many drafts and tentative posts it’s also a good thought to go by them and undo what we don’t need.

wp_term_taxonomy database tables.

Therefore, deletion nonessential plugins and themes can giveaway adult poignant space in your database. However, for that we have to undo them, instead of deactivating.

Table upkeep Optimize table option runs a
OPTIMIZE TABLE MySQL-query for a comparison tables and removes a overhead of your database.

If we have a corrupted list in your database we can correct it by selecting a “Repair table” option (it’s next “Optimize table”) that runs a
REPAIR TABLE MySQL-query.

define( 'WP_ALLOW_REPAIR', loyal ); line from a
wp-config.php file, as a database optimization apparatus can be accessed by anyone not only by admins.
4. Trim your database with plugins

Below, we can find a best giveaway plugins we can use to serve trim your database. These plugins also perform some of a tasks we mentioned in a “Manual clean-up” territory that means you don’t indispensably have to do these manually.
The WP-Optimize plugin removes trashed and unapproved comments, pingbacks, trackbacks, lapsed transitory options, cleans a
wp_postmeta list and orphaned attribute data, and has many other good features.
In a options panel, we can name that tasks we wish to perform. Moreover, we can also schedule involuntary weekly clean-ups, according to your specification.
The WP Sweep plugin has identical functions to a aforementioned WP-Optimize, for instance, it can be used to mislay trashed posts and comments, duplicate post meta, transitory options, orphaned meta, etc.
WPBeginner has an interesting post in that they disagree for WP Sweep (as against to WP-Optimize) as it “uses correct WordPress undo functions as most as probable instead of using approach undo MySQL queries”. Both plugins are great, choose whichever we like more, we won’t go wrong with any of them.
With this plugin, we can undo trashed items, lapsed transients, pingbacks, trackbacks, spam, etc. Moreover, we can opt for keeping a record and set up an hourly, twice a daily, daily, weekly, or monthly optimization scheduler.
Just as a name says, before a database optimization, it deletes post revisions that customarily take adult a outrageous place in a database. In a options panel, we can name how many revisions we wish to keep and also a age of a revisions that can be deleted. This plugin is multisite-compatible as well, that is a outrageous plus.
