 Description   

TokuDB currently does not support virtual columns. When trying to create a table that does, for example

CREATE TABLE test (
 
    str1 varchar(10) NOT NULL,
 
    str2 varchar(10) NOT NULL,
 
    combined varchar(20) as (CONCAT(str1, str2)) PERSISTENT
 
) ENGINE=TokuDB;

one gets an error message

ERROR 1910 (HY000): TokuDB storage engine does not support computed columns

It would be really nice to see support for virtual columns in TokuDB as well.

Yes – it's been sitting around without any activity / movement for 6 months now. Not really progress in my book.
