При попытке выполнить optimize table history_uint :
MariaDB [zabbix]> optimize table history_uint;
+---------------------+----------+----------+-------------------------------------------------------------------+
| Table | Op | Msg_type | Msg_text |
+---------------------+----------+----------+-------------------------------------------------------------------+
| zabbix.history_uint | optimize | note | Table does not support optimize, doing recreate + analyze instead |
| zabbix.history_uint | optimize | error | Temporary file write failure |
| zabbix.history_uint | optimize | status | Operation failed |
+---------------------+----------+----------+-------------------------------------------------------------------+
в то же время, если выполнить optimize table history, то :
MariaDB [zabbix]> optimize table history;
+----------------+----------+----------+-------------------------------------------------------------------+
| Table | Op | Msg_type | Msg_text |
+----------------+----------+----------+-------------------------------------------------------------------+
| zabbix.history | optimize | note | Table does not support optimize, doing recreate + analyze instead |
| zabbix.history | optimize | status | OK |
+----------------+----------+----------+-------------------------------------------------------------------+
