in Mariadb - Can you cache the indexes and data for Aria Storage engine tables?

I have a table that is a read-only table (real-time view), I used Aria based on the recommendation for read-heavy workload. Based on this https://dba.stackexchange.com/questions/1/what-are-the-main-differences-between-innodb-and-myisam?noredirect=1&lq=1 When it comes to cache is Aria like MyISAM or like InnoDB? meaning, Can I cache only indexes or can I also cache the data? (under the assumption I have large enough RAM)
