phpMyAdmin is a third-party tool that you can use to manipulate MySQL® or MariaDB® databases. For example, you can use phpMyAdmin to add or delete records in a MySQL database. For more information about how to use phpMyAdmin, visit the phpMyAdmin website.
MySQL 8.0 caching
MySQL 8.0 enables caching by default. This means that unless you configure MySQL, changes to your tables and their metadata may take up to 24 hours to appear in the phpMyAdmin tool. For example, if you remove data from a table, the table’s size will decrease, but the phpMyAdmin tool may continue to display the original table size for up to 24 hours.
To configure MySQL caching, use the information_schema_stats_expiry variable. For more information about how to use this variable, read MySQL’s 7.1.8 Server System Variables documentation.
