Now should i cache very rows?

Hi, heres my table:


CREATE TABLE `stats_css` (

 `id` int(10) unsigned NOT NULL,

 `reliability` tinyint(3) unsigned NOT NULL DEFAULT '100',

 `ragequit` tinyint(3) unsigned NOT NULL DEFAULT '0',

 `played` int(10) unsigned NOT NULL DEFAULT '0',

 `won` int(10) unsigned NOT NULL DEFAULT '0',

 `drawn` int(10) unsigned NOT NULL DEFAULT '0',

 `lost` int(10) unsigned NOT NULL DEFAULT '0',

 `assists` int(10) unsigned NOT NULL DEFAULT '0',

 `kills` int(10) unsigned NOT NULL DEFAULT '0',

 `deaths` int(10) unsigned NOT NULL DEFAULT '0',

 `roundswon` int(10) unsigned NOT NULL DEFAULT '0',

 `roundsdrawn` int(10) unsigned NOT NULL DEFAULT '0',

 `roundslost` int(10) unsigned NOT NULL DEFAULT '0',

 `headshots` int(10) unsigned NOT NULL DEFAULT '0',

 `damagegiven` int(10) unsigned NOT NULL DEFAULT '0',

 `damagerecived` int(10) unsigned NOT NULL DEFAULT '0',

 `bombsdefused` int(10) unsigned NOT NULL DEFAULT '0',

 `bombsplanted` int(10) unsigned NOT NULL DEFAULT '0',

 `1man_played` int(10) unsigned NOT NULL DEFAULT '0',

 `1man_won` int(10) unsigned NOT NULL DEFAULT '0',

 `2man_played` int(10) unsigned NOT NULL DEFAULT '0',

 `2man_won` int(10) unsigned NOT NULL DEFAULT '0',

 `3man_played` int(10) unsigned NOT NULL DEFAULT '0',

 `3man_won` int(10) unsigned NOT NULL DEFAULT '0',

 `4man_played` int(10) unsigned NOT NULL DEFAULT '0',

 `4man_won` int(10) unsigned NOT NULL DEFAULT '0',

 `5man_played` int(10) unsigned NOT NULL DEFAULT '0',

 `5man_won` int(10) unsigned NOT NULL DEFAULT '0',

 `maps` text COLLATE utf8_unicode_ci,

 PRIMARY KEY (`id`),

 CONSTRAINT `stats_css_ibfk_1` FOREIGN KEY (`id`) REFERENCES `users` (`id`) ON DELETE CASCADE

) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci

id refers to user, and every user have one row here

so stats should be selected very offten, since self user and other users can check stats in pre lobby

so i would to cache to prevent MySQL acesses, and renew cache when player finish a game

now should i cache this?

set a cache name per user like: "user1", "user2"?

another question: Yii save cache into files, and only put in memory when we access to it?

NOTE: Using APC

thanks

check data cache http://www.yiiframework.com/doc/guide/1.1/en/caching.data#query-caching

yeah i already check, but the question is other

the question is about performance and how to cache many rows that can be more than 10000 without blow php

thanks
