The Ultimate Guide to High Availability with MariaDB

Where is the table_cache in MariaDB?

All versions of MariaDB are based on MySQL 5.1 and greater, thus the table_cache option is deprecated in favor of table_open_cache. This is also documented at: mysqld Options (full list).

For further reading, please refer to the MySQL manual: How MySQL Opens and Closes Tables.

Examples of use cases:

MariaDB [(none)]> SHOW GLOBAL STATUS LIKE 'opened_tables';
+---------------+--------+
| Variable_name | Value  |
+---------------+--------+
| Opened_tables | 354858 |
+---------------+--------+
1 row in set (0.00 sec)

MariaDB [(none)]> SELECT @@table_open_cache;
+--------------------+
| @@table_open_cache |
+--------------------+
|                400 |
+--------------------+
1 row in set (0.00 sec)
