What It Does

Delete old, expired transients from the WordPress options table to prevent them from bloating your database and slowing down your website.

WordPress stores transient records in the options table. Many transients have an expiration time, but they often remain in the database after expiration. This plugin schedules a daily task to delete expired transients efficiently.

It performs this operation with a single SQL query and runs a second query to remove orphaned expiration records. This plugin is optimized for fast performance and maximum compatibility.

Now optimized for WordPress Multisite, it does not collect personally identifiable information and helps reduce potential data leakage.

FAQ

According to Codex, transients are:

a simple and standardized way of storing cached data in the database temporarily by giving it a custom name and a timeframe after which it will expire and be deleted.

NB: by default they are stored in the database, but if you have an object cache like memcached they won’t be.

Here’s a few useful SQL queries to run in MySQL when you are trying to debug what’s happening with transients.

-- transients that are not autoloaded (should be all with expiration times) select option_name, option_value from wp_options where option_name regexp '^(_site)?_transient_.*' and autoload='no' order by option_name;  -- transient expirations select option_name, option_value, from_unixtime(option_value) as expiry_time from wp_options where option_name regexp '^(_site)?_transient_timeout_.*' order by option_value desc;  -- transient expirations with paired transients (inc. orphans) select t1.option_name, t2.option_name, t1.option_value, from_unixtime(t1.option_value) as expiry_time from wp_options t1 left join wp_options t2 on t2.option_name = replace(t1.option_name, '_timeout', '') where t1.option_name regexp '^(_site)?_transient_timeout_.*' order by t1.option_value desc;  -- expired transient expirations with paired transients (inc. orphans) select t1.option_name, t2.option_name, t1.option_value, from_unixtime(t1.option_value) as expiry_time from wp_options t1 left join wp_options t2 on t2.option_name = replace(t1.option_name, '_timeout', '') where t1.option_name regexp '^(_site)?_transient_timeout_.*' and t1.option_value < unix_timestamp() order by t1.option_value desc;
